ESP32 Forum

Hi,
I'm here again regarding my board.
I've done a v2. Based on v1 hand modified.
But now I can't drive GPIO3. It was previously working.

I checked, I have the same ESP32-C3 module as before : M4N4.
I also have the same code.
I checked the datasheet again, and GPIO3 doesn't seem to be reserved for other things.
Can someone help me ?

Hi,

Can you please provide us with more details about your project. Sharing the schematics is always welcome.

Here my schematic.
I'm using GPIO3 to send a BLE State to my PIC18 to control the LED.
But after configure the GPIO3 as an OUTPUT on Arduino IDE, nothing came out.
If I'm using same code in Arduino but change GPIO3 by GPIO6 it is working perfectly as it should !

As I said, it worked fine on previous version of my board.

Thanks for the help.

Issue solved! It was only my load (the PIC18) which didn't take changes about this pin and grounded the pin.
