I am new to Arduino and Controllino, have some programming and electrical skills. I get the I2C display to work on an Arduino Uno, but not on the Controllino Mini. Connections are: 5V, GND, SCL and SDA on Controllino and 5V, GND, A4(SDA) and A5(SCL) on Arduino Uno. Even using the Address scanner i2c_scanner gives no results on Controllino, and 0X3F on Arduino Uno. Tested two displays. Any ideas?
