You can hook up I2C bus on almost any pins, you just need to provide pins number in the begin() function.
Personally, I'm using GPIO0/GPIO2 since they also need PullUps for boot mode, so perfect for I2C bus too.
But if you don't provide pins, they will be defaulted according to the board variant, Generic is 4/5.

Code: Select all
Wire.begin(0, 2);
