Hello, I have a board that always outputs a high signal on all D pins. I tried to completely erase the firmware, but even without the firmware loaded, it still outputs a high signal on all pins. The LED on the board is lit. In your opinion, what could be the malfunctions? Could it be that the chip itself is broken?
Bhai mere NodeMCU ek bar code upload hoke kam kiya uske badh maine jab plug kiya toh USB not recogonized aara hai cable change kar liya , driver download kar liya , reset karliya ab kya karu
How to repair the esp8266 if the wire i.e going to be connected in ground get into sk pin by mistake. Now esp8266 is not working , what i can do or should buy a new one....😢
when i check the pins with multimeter in buzzer mode the 3V pin are shorted with G pin. i have black component that write on (100 6V) on it and its shorted too.
Brother ! My Nodemcu is not receiveing any codes and showing the same error again and again.. The led lights are also not blinking... We have done all possible things we could do.. But also it is having same problem.. Does this mean that our Nodemcu is shorted ??
Please help me 😭 I short circuited the board and before changing the diode I checked it by short circuiting the diode and the led didn't glow but when I short circuit my board now with vin and ground some sparks is coming but the code is not uploading 😭😭
My nodecmu is heating and blue light ain't showing anything, Mistakenly i've applied 12v to Vin thats why it get shorted and my 3 nodemcu are destroyed with that any idea what to do please help??
brother main rc car code upload kiya aur prefect work kiya .lakin abhi me same code apply kre rha ho aur code upload bhi ho jata h lakin android app se control kane pe rc motor work nhi kar rha h.motor driver bhi ok h aur mcu ka light bhi on hai. kya problem ho sakti h?
Awesome project
Thank you bhai❤
It's work buddy .thank you so much.I was about to throw it away
🎉❤️
Well explained
♥️♥️
Bro can I use 1N4008 instead of 1N4007

It helped a lot brother, thank you
You're welcome!

Bro when i conmected to port it will directed in my laptop but code is not uploading and power led also not turnimg on what's the problem
What happens if it gets short again
Will this diode protects from short circuit again?
Diode is for reverse voltage protection so if it again shorted you have to replace it again with the new one
how about EsP32 i have one with no power.😅

I have esp32-cam and I was gave it to 5.3 v and 3.4 A so its regulator IC 1117 3.3 D135was burned and indication LED also burned, So will it repair .
yes but only if your diode is burned otherwise if microcontroller is shorted you need to replace smd Microcontroller
my nodemcu are work fine but its consumption current are about 450 ma . the regulator and Esp12e are getting HOT. what should I do?
when i check the pins with multimeter in buzzer mode the 3V pin are shorted with G pin. i have black component that write on (100 6V) on it and its shorted too.

Yes, try to replace diode and check it's working or not

Try it by replacing diode
@@tscdevloper I have replaced it but it is not working 😭
Is the chip present in the board has
gone?😭
Wish I could hear you over the music! Why?

Bruh replace voltage regulator diode with new one as like me which I shown in video do it for all 3 nodemcu
@@tscdevloper ohk bro thanks. I will try...
Hi can I use 1n4004
Yes bruh it's maximum reverse voltage is 280V so you can use it easily..
@@tscdevloper thanks bro you helped me a lot ❤️ love from gujarat

ek bar node mcu ke pins pe signal aa raha hai kya dekho jidhar driver ko input diya hai like HIGH and LOW
i can't upload any code its not connecting
If you soldered it correctly then it must work correctly ...
