Hi @mariocondesantos,

Thanks for using my library. You can change the ESP32 I2C pins in your sketch:

Wire.begin(SDA_PIN, SCL_PIN);

But change general I2C pinout in my Esp32 and my display stops working... My display use I2C also... image image

Are the DS3231 examples up and running on your ESP32 board without using other devices? Make sure the DS3231 I2C pins uses different pins as they cannot be shared with a non I2C devices. Multiple I2C devices can be connected to the same I2C bus when each device has a unique address.

Closing issue as ESP32 I2C pin configuration is beyond the scope of this DS3231 library.
