I2C Pins on ESP32-PICO-KIT V4.1

Postby Serena Yeoh » Wed Oct 16, 2019 3:40 am


I apologized if this is a dumb question, I am new to ESP32 and not from EE background. I would like to know where are the I2C pins on the ESP32-PICO-KIT. I cannot find much information on this board and I can't see any labels for the SDA and SCL pins in the documentation on the espressif site. I have tried pins 21 and 22 which are the usual pins for ESP32-WROOM-32 Dev Kits but they don't work for the ESP32-PICO-KIT.

I would very much appreciate your help.

Thank You.

You can route i2c pins to almost any gpio, that's why there is i2c_set_pin function

I am not sure what to say here because moving my I2C project from my ESP32-WROOM-32 Dev Kit worked just fine on the Pico Kit using the same pins. Do you have a ESP32-WROOM-32 Dev Kit, that you tried the I2C on first ?
