Hello,
I have a lolin32 lite and there is no pin 21
in arduino IDE theoretically we can put the pin that we want with I2C
I am trying to connect a mpu 9250 and I can not find any tutor who uses this method
Can you help me, please ?

Lolin32 I2C :
Pin 15 for SDA
Pin 2 for SCK
Built-in led -> pin 22
Regards.

SDA pin 23 and SCL pin 19 work fine also using lolin 32 lite.
Better than SDA 15 and SCL 2, because pin 2 is used during the bootlooader process and you need to disconnect it to flash your board.

ESP32 can use any pin for SDA SCL, as you want (if another function dont use this pin also).
