Hi, you do because of the high current. The Pi can power the board but it's recommended that you use a separate power for the servos or any high current like DC motor. Using the same power might cause the pi to restart when the motor start
@@techs.passion cool, that make sense, because i got myself the big hexapod robot kit, their servos board was faulty (waiting for 3 weeks for the new board) for the moment i bought my one PCA9685 and joined another one. but I have the ultrasonic sensor, camera and giro from the hexapod that i dont know on which pin to put and im using the rasp. Pi 5
The Raspberry Pi 5 is an overkill for this, I would recommend using Arduino or anything cheaper. The R Pi 5 will do it for sure but it's expensive and it weight more than you need. Regardless, let me know if you need any help with it. Thank you for stopping by and for watching

Yeah so you want a separate power for the board and another power for the RPi. This way you keep the load for the motors from impacting the RPi and your software. Plug in the servos to the board but make sure the power is separate. I have a good video about this, let me find it for you
Is there an EXTERNALLY-MANAGED file in the directory if so, I think the fix is to remove it and then install with pip3 It's hard to know for sure but I really hope this helps and I hope I got it right but do not hesitate to keep asking if you need further help

I've been using the 9685 servo driver for a few years and it certainly makes life easier.
100% agree, this is how I made my spider bot. Thanks for watching
Thank you! Really appreciate your work, especially the links that solved problems - such as the 'EXTERNALLY MANAGED' error.
Great to hear! Thank you for watching
Amazing video, helped me with the externally-managed-environment issue
Thank you so much for watching! I'm glad the video was helpful 🙂
Thanks!
Thank you so much, that is very nice of you. Let me know if you need any more help
Thank you for posting this!
Glad you enjoyed it!
You explained everything so clear.. Good job and thanks!
Glad it was helpful! Thanks for watching
life saver for vnc server users
Thanks for watching
Bro all of the documentation is either confusing or hard to come by for latest versions, thanks for the vid. Liked and subbed.
Glad to hear this helped, thank you so much. Let me know if there is anything else you like to see
hi, can i know why you need to power the servo board, i thought the raspberry pi could do it

doesn't work, error codes everywhere
Sorry to hear that. I'm guessing it's the library missing or not installed correctly. Did you search the error or can you post it here?
I would you ever make a vid for controlling the pca9685 with a pi pico ?
Good idea, I have it for Arduino and Raspberry Pi but never for the Pico, I will keep this in mind. Thank you
no i2c device address at 0x40
Is that the error code you are getting?
@@techs.passion I am also getting the same.
I see, I would check the connection and make sure it's powered on but let me try to research it more and get back to you
Very useful video, thanks 😊 👍
Glad it was helpful!
Thanks a lot!
I'm glad this helped, thank you for watching
Not working....
Sorry to hear, want to share more I will try to help, what error are you getting?
HOW TO FIX externally-managed-environment: sudo rm /usr/lib/python3.11/EXTERNALLY-MANAGED
Hi Sorry for the wait, based reading the error my guess is that this is something related to installing the Python package.
@@techs.passion how can i fix?
Is there an EXTERNALLY-MANAGED file in the directory if so, I think the fix is to remove it and then install with pip3
It's hard to know for sure but I really hope this helps and I hope I got it right but do not hesitate to keep asking if you need further help
