IC2 Pinout ESP32-S3 DevKitC 1

Postby stemwomen » Wed Apr 17, 2024 11:52 pm

  1. I need help figuring out the default I2C pins for the ESP32-S3 DevKitC 1 model. I have esp32_hal_i2c.h and LiquidCrystal_I2C.h included in my code and other than that nothing that should change the device pinouts. I am trying to find the SDA and SCL pinouts. Please and thank you.

The default on esp32-s3 is 8 & 9, but you can assign them to whatever you want with Wire.begin(sda, scl);
