- A quick explanation on how to power your APM 2.5 mega (Arduflyer) unit. See my setup guides 1-4 for this controller on my channel.
APM 2.5 controller- A basic setup guide
You can buy the flight controller with compass here: amzn.to/2SjnAJn
You can buy the power cable here: amzn.to/39mCc1B
In your case
-The power module will power the APM module itself(and RC receiver, GPS unit that connected to the 'INPUT SIDE ' of the APM unit)
-Do not use the JP1 jumper .
-Your Turnigy ESC will supply 5 V to the 'OUTPUT SIDE' . Leave the red wire intact on your ESC since you have only one ESC on that side.
-Your servo also connected to the 'OUTPUT SIDE' will take power from the 5V ESC supply .
-Your motor is not powered from the APM board but from the Main ESC wires connected to the LIPO.
Thank you ! Explained very well and THANK YOU for that !!! It was very confusing in the way it was explained on all the websites which I visited!
You must disconnect the APM board USB connection from the laptop before you port it via the power module.
I believe you can also dual supply to both inputs and outputs side with JP1 disconnected. I split 1 ESCs power + and - from the signal and plugged it into the inputs side, then the rest of the ESCs into the outputs side with JP1 disconnected.
Yes you can power both sides with the JP1 disconnected but do not power the input side with an ESC , use a dedicated BEC or the power module designed for this.
Thanks. Critical & important info.
Thank you very much! It helped a lot. I was really confused but now I got it :)
Thank You! Very good explanation.
Exactly what i needed. Thankyou
yes, only the red wire . leave the black (ground) and the signal (yellow or white) cable
The other end leads to the power distribution board for the motors. The power module only supplies battery power to your flight controller .
Hey 75echo
Nice video, you answered my question spot on. THX :D
godt arbejde makker ;)
Wow. Thank you for explaining this in plain english and how the circuitry of the board works.
Question, is this JP1 jumper info the same for a 2.6 APM?
yea the same
Very good job.
Very informative, thanks
What about power coming from the receiver into the input pins? Is it safe to have 5v power from the rx (without the jumper)
Hi again Ahmed, powering your APM via the ESCs is not something that I recommend due to the risks of "brown outs" . Get a dedicated power source for your flight controller please.
Thanks for the great explanation. The manual wasn't so clear.
An excellent explanation. I am building my first quadcopter around the APM solution. I have watched dozens of videos & tutorials. Even as an electronics engineer most tutorials are ambiguous and confusing. Your explanations are clear and unambiguous. Without wishing to be condescending in any way your use of English to covey the facts clearly is a breath of fresh air ! Good job, I look forward to more videos. Cheers Dave UK
I am glad that you found this helpful. Happy flying and do not forget to subscribe to the channel or like the video.
great video, where did you get your APM unit from, thanks
Just one of the +5V ESC leads, cut the rest carefully.
Hello from Greece...nice explain..i'm bit comfused and need advice,,,,at output...if connecting servo...and jumper is not connected...have power on servo? or need Bec?,,,
Why is there two battery ends on the power module. I understand that one end is where the battery is plugged into, but what is the other end used for?
I am a photographer without too much knowledge in multirotor. I just bought a new APM 2.5 board with power module. I assume the APM will be powered up when it is connected to a Lipo battery with JP1 disconnected. However, nothing happens until I plug in a micro USB power source. I just want to know if it is normal before I assemble the flight control system in my multirotor. If it is not normal, then I can return the product. Thx slot.
Thanks a lot
You are welcome
Thank you sir.... i dont know about that jumper lucky me found your youtube
buen video, gracias por ayudarme en las algunas interrogantes que tenia
Do you know what type of plug the PM plug is ?
Thanks for sharing! Definitely cleared up some confusion I had regarding power supply.
of course, go for it :-)
thank you for this
Trying to trouble shoot a problem... I have the APM power module plugged in, JP1 OFF, but I did not remove the red wire on my Q-brain ESC (its a 4in1 ESC w/BEC). In effect I was then supplying 5v simultaneously. While flight testing the quad suddenly lost power and fell dead from the sky only damaging a prop.. The Battery connection looks questionable which I'll re-solder, but could it be because of the dual 5v on both sides of the APM?
Great video!!! I want to use this on Vtail quadcopter (flitetest batbone). Would this work on this quad setup?
thank you!
Always love your videos, is there any harm to connect a 24 volt lead acid battery to the power module
No you should not, maximum input voltage is 4S lipo (18v).
Thanks friend. You solve my big problam. I smash subscribe botton.
Glad to be of help.
Why cant we connect USB while powering via power module ?
shouldnt it handle the voltage and keep it at 5V ?
If you use Opto esc's you will need the jumper.
Can I power the receiver directly from a UBEC and draw that power to the FC through the input cables?
yes, if you do not have a separate power module for your HKpilot, and you plan to power it from the ESCs you will have to leave the JP1 jumper on. To be on the safe side cut the red wires from the ESC except one which will power the board. Even though this setup will work,i do however always advise a dedicated power module for your flight controller.
it wont cause any problems if you are not using the JP1 jumper and if you do not have any servos. If you are not sure just cut the others and leave only one.
Your APM control board should power up when you connect it to a USB power source. Note: do not connect he power module /lipo and USB at the same time!
Hi. Just wanted to ask...if you use the power module and the jp jumper is off, do you plug the esc cables in the output with all 3 wires or just the signal yellow wire?
I was really very confuse about it...but you are very clear about it...
People like you make You Tube awesome, Thanks for the info.
I have my board wired and set up to use the power module but when I connect the lipo nothing happens (no lights from board) except the escs beeping. somehow I think the power is not getting through the board to the rx and gps. do you have any suggestions? The board connects to the laptop fine and I have calibrated everything that I can so far.
Damn i have a problem.
I use the BEC from my QBRAIN 4x25A (BEC 3A) to power the Micro HKPilot. I soldered the small pad SJ1 to power the board by ESC BEC
It seems that my RX is not receiving enough power. I use a OrangeRX 9 Chan receiver. i measured the Voltage only 3.85V. If i power With a 5V UBEC on the ESC side of the power board and disbale the power from the ESC by removing the VCC pin. Should this help
Hi
i have this settup on my multicopter
1 apm 2.6
4 Afro ESC 30 AMP
1 FrSky receiver
1 Tarot Ironman 650 frame
4 390kv turnigy multistar motor
1 GPS module
1 telemetry Module
1 4s 5000 mah Battery
1 APM power module
i want to use a custom pair of servos to retract landing gear
i have a Turnigy 5A external Ubec ...my question is
Where do i have to connect the external UBEC?
i have to disconnect the power leads of the ESCs?
do i have to connect the External UBEC + APM power Moudle + ESC BECs?
I have to connect the External UBEC to the reciever and leave the the power module and the power leads of the 4 ESCs connected?
Where do i have to connect the landing gear servos to cntrol it ?
i am really confused :/
thanks for that :)
Help Ahmed, the throttle can be reversed from the mission planner configurations, if this does not work then reverse it in the settings of your 9x transmitter.
If I power the APM using the included Power Module and I'm using a servo, would it be safe to use a 6V ESC plugged into the output rail? If so, what might the wiring look like? I'm looking to switch my brushed ESC controller for a brushless, and all that I have found have use 6v BEC.
Hi
I have been following your detailed tutorial. However two issues: 1) on my computer setting my 9x tx throttle seems to be going the opposite way power down instead of going up. I have done thr reserve still thesame. 2) my 4 in 1 25A esc won't power the APM. Any ideas plz?
Thanks
Hello 75echo, i'm wondering where can I find this little piece for the jp1? if you know somewhere where I can buy it I would appreciate it. Thank you very much! Nice video, I understood it perfectly thanks :)
I bought my APM sensor on Ebay for a good price as I am on a strict budget, I know, this may be unwise, but as it turns out, it looks like the real deal and the cable is correct for APM multi pin input. I wonder if you would comment on the Attopilot PM and why anyone would use this over the type you and I are using? And with only 3 wires to the APM board this way. How, I wonder do they derive power for the board, a current and voltage reading and a ground connection with only 3 conductors? Anyway, you have produced a good video, I have subscribed some time ago and I am going to watch the rest of your uploads regarding the APM. I was just thinking that I may be poor in cash,... But I am rich with RUclips tutorials:-) :-)
Hi 75echo
I'm wondering if you can help, I have a current sensor fitted and having installed it as per the instructions my OSD keeps flashing "BATTERY LOW" even though the battery is well charged and the OSD show's this, how do you have yours set up, to date have tried may things without success, Regards Geoff
Thank you for clarifying this! If I am using the power module and I have OPTO ESCs that have no BEC, does JP1 still remain uninstalled? I ask since I plan to use a UBEC on the output side. Thanks!
Quick question, I'm planning on connecting my APM 2.5 with a Raspberry Pi over UART serial. I'm using a level converter from Bitwizard to handle the voltage conversion but I want to make sure that I won't have any trouble having the APM connected to a power module while also connected to UART0. It's not actually being powered via the serial connection right? I know it gets sensitive about being connected to a PM and a USB at the same time. Or should I be using UART2 instead of UART0?
Hi! Thanks for your explanation! But i am wondering how a power supply with a 5s 5000mAh LiPo would work? Thanks for spport!
it would work the same way.
How did it go?
Hi, when not using the power module, i will plug the jumper. But when using a quad does that means i have to use 3 opto (remove the red wire) ESCs and one normal esc? Thanks :))
hi friend. I have a problem with my X copter. its so late arming and some time don't arming ( in the mode stabilize ) and blue light is on.. gbs look..
my apm is 2.6
dude. this clip is f**king helpful to me
Awesome videos dude. I am getting one soon ;-)
thanks a lot
I wonder what the total milliamp draw on the power module when it is providing current to the APM and all it attatched: 3DRTelemetry radio, a telemetry type Rx like the FrSky d series, the GPS and the OSD. Anyone care to hazzard a guess? Now you add a servo driven dual axis servo driven camera gimbal what then? Is this where the ESC BEC comes into play? Congrats on producing such concrete and useful video content 75Echo. I find myself reaching for the subscribe button Happy Flying to all
Your Q-brain only has one power lead and the rest are just one gnd. and four signal wires correct? It is ok to have one power lead into the motor outputs. According to what I have read and what this gentleman has described. If everything is working again then you didn't fry anything. If not, :-( then you have done some damage perhaps. I hope you don't mind if I take up the slack here and try to voice an educated guess :-) Happy Flying Mate
that power board has a shunt resistor that can fail if you exceed the max current or if is no a good quality, in that case you will remain without energy on the motors, so is not a good thing. I prefer powering my APM from linear escs so iven if 1 esc go bad i still have power from the others. this is just my idea. for the current consumption to be measured a hall effect sensor will be more safer and more precise
Thanks. As you said the Wiki is confusing and most other explanations as well. Your video and responses to questions have cleared up a lot for me!
Hello prashanth, the APM module accepts a number of ardunio compatible GPS units , however i recommend that you do not skimp on the GPS unit and choose a cheap non sensitive chip. If you go to the we page buildyourowndrone(dot)co(dot)uk you will find a list of compatible GPS units for sale. The more sensitive and reliable your gps unit is, the better your enjoyment of your aircraft with less risks as regards autonomous mission execution.
if i use the power module to supply power to the whole board with the jumper, do i just need to remove the middle wire from my four esc and it will be good? btw i have linear tye of esc. if that is the case i would rather just using the power module and leave the jumper on and not use the power from the esc
Noob here.
I am using a F450 flamewheel frame with the apm 2.5. Do I connect the receiver to the board where the battery is connected?
If my ESCs are opto and I use external BEC, can I connect the BEC to PM port and still leaving the jumper off?
If I don't uses the jumper, will the OUTPUTS need power no?
Say you have an RC configuration and inserted Y cables between receiver and servos/ESC. And then you plugged one branch of Y cables to input ports of apm to just listen. Nothing is connected to output port of apm. Now the apm is powered via the ESC however from input relay. Should use the power circuitry and/or should plug jumper in?
if you are flying a quadrotor, would you need to disconnect 3 of the 4 red wires from the ESC's to prevent too much voltage being supplied to the APM 2.5? ive read this is the case with the DJI Naza. it says you need to cut 3 of the 4 red power wires. is 5 volts from 4 ESC's still just 5 volts? or is it multiplied into 20 volts?
interesting and helpul info !! thankyou
If I use the jumper and the ESC option for a quad, will all my ESCs provide voltage and power to the board?
dude i habe bought ArduCopter 3DR-C QuadCopter Kit plz help me in powering my apm i m confused with PDB,PM,ESC's,MOTORs and the jumper thing .Can u provide me the single detailed diagram showing all the connections between these things !!!
Thanks in advance
Good video , just what ive been looking for , just one thing tho , im installing my apm with power module on a plane and using one esc " turnigy trust 55amp , will i have to disconnect my red 5v wire ? or is that whats going to be powering my servos and motor ? thanks.
Dear Sr. 75 echo, I brought a hkpilot 2.5, it is the same as APM 2.5 ARDUPILOT, also brought 4 HOBBYKING BRUSHLESS ESC 30A BEC, do I have to cut red wire to 3 of them to power the electronic device for my quadcopter? I do not have to take off the jumper JP1.
Can I power apm2.8 without power module in my quadcopter
I wish they would put a link to this video on page 1 of the RC forums Ardu 2.5 thread! This is the best explanation I've seen. It appears an explanation of the "red wire" ESC problem is also needed. Thanks for a great video.
Hey mate I'm putting the apm in a plane to power the out put side for my servos will the esc for the motor be enough to power the whole out out side? Any help would be awesome
Thanks for the advise.I have seen 5 of your videos, they explain in a simple mode, I am working on my first UVA, its my first RC toy.The next step is an octocopter. I live in Bogotá Colombia SA. Good Luck.
If you use OPTO ESCs they will need power in the signal side. By putting in the JP1 bridge the APM supplies the ESCs from the PM. This is perfectly OK as the OPTO ESCs do not have a BEC.
Wouldn't it be smart to only cut the red cable and leave the black?
Normally you would like to maintain ground to isolate the signal cable better from interference.
Dear Sir, I have owned HKpilot MEGA 2.5 but i have Turnigy Plush 40A ESC Linear BEC with 3A 5V output. can i power my HK pilot from it?
Thanks and Regards
But what is i split my escs power from the signal and used the esc power on the input side keeping the esc signal on the output side. Is this ok?
ok thanks you have already answer GREAT JOB my friend we all thank you
you explained this the best out of all the videos I've watched!!! thank you
Thanks a lot!
Is it necessary to connect all of the +5v ESC's wires to the board of just 1 of them?
(I have hexacopter)
really nice explaination
Thank you, more content on the channel that may interest you.
Can I use any other GPS if possible kindly specify name of GPS
i use any 3 cell lipo from 3600mah to 5000mah
I wish i could but unfortunately it is not as straight forward as that because one any diagram will depend on your hardware components that you intend to use. The APM wiki page contains various diagrams for various hardware setups and the APM2.5 board is well labeled for you to see where to connect the various components.
Hi Geoff, i have just disabled the alarm on mine and i use a lipo buzzer to know when its low. Try going into mission planner under configuration , make sure your correct battery capacity is selected , likewise select the the current sensor you are using. Also you can set the battery alarm level that triggers the 'Battery low' warning.
Hello, i am not really sure if i understood your question but i can safely mention that you should not use a Y cable between the ESCs and servos if you are also powering your APM board from the same ESCs. Your servos should be powered via the APM board.
The power module is a Switching regulator.
One xT60 end takes 12 v from the lipo directly, sends it to the power module which converts it to a clean 5 v for the APM module, the other xT60 end takes the same 12V supplied from the lipo to the ESC and motors.
Thanks for putting it in simple terms
Apm 2.8 output 1 port not working. What's I do
Hi Great video i'm new to this but i need some information on this Power Supply explained
Question: if i plug in the ESC's without the jumper does the BEC's on the ESC do anything ? would it be ok or do i have to cut the middle wire from the ESC?
If your esc BEC is of the linear type then you should be fine but if you have switching type BECs from your ESCs then you are advised to Cut the red wire from all the ESCs apart from one which you leave intact.
75echo Thanks so much for the info keep up the great videos
Thank you verymuch for the explanation Mr.75echo.. :-)
