i2C 20x4 Display on Controllino Mini

Post by sturze » Wed Apr 29, 2020 3:23 pm

Hi!

i have a 20x4 I2C Display on my Controllino Mini connected to the 5v, GND, D6 and D7 pin on the pinheader.
Running a simple LCD test sketch is working on 5V via USB, but powering the Controllino Mini, the D6 pin goes off quite quickly after powering, so does the LCD.
Switching back to USB everything is running just fine.
Whats wrong?!?!

Hello,
please, is the CONTROLLINO working without the connected LCD.
