Looking at the datasheet I see that the GPIO numbers are not continuous.
Is there any logic for it?

For example there are no GPIO 22-34 or 43-44

That is not the same for other ESP32

Thanks!

Did you try adding some caps? I have a project with ESP32 and MCP23017, powered from an external 5v PS and it works well: https://github.com/crgarcia12/electronics-workbench-controller/tree/main I am not sure if this will solve your problems, but I added capacitors to the MCP in case it needs sudden...

I had this issue, and in my case was that I was setting GPIO 8 as a Digital Input.

Hi, I am trying to get serial data from my custom build wroom s3 board (https://github.com/crgarcia12/electronics-homeassistant-lightscontroll) I have the simplest possible code: void setup() { Serial.begin(9600); Serial.println("Hello"); } void loop() { Serial.println("Loop"); digitalWrite(1, HIGH)...

I made all of these with jlcpcb.com:

I had no issues

I have an ESP32 with ESPHome. From time to time, it resets by itself. I suspect a problem with power or spikes (since many times it happens exactly after energizing a relay. When I read the reset_reason, I get [21:20:13][D][debug:199]: Reset Reason: Power On Reset [21:20:13][D][debug:244]: Wakeup Re...

Thanks a lot for your answer ESP_Sprite!

I am trying to copy the ESP32 DevKit USB behavior in my own PCB ( my pcb project ). When the USB is plugged, ESP should be powered from USB. I will use this to program the board only When the USB is not plugged, the ESP should be powered from the PSU. This is how the board will be used in normal ope...

Hi, I am new with ESP32. I installed all the tools from the official website and then the VSCode extension following the wizard. I can build and flash the program into the WROOM ESP32, but I am unable to debug: Open On-Chip Debugger v0.10.0-esp32-20191114 (2019-11-14-14:19) Licensed under GNU GPL v2...
