Cactus Micro REV2 and QC1602a LCD

How can i connect a QC1602a lcd to my cactus micro rev2 ?

Can anyone explain to me which library to use and how to connect ?

Check out this page, it contains very useful information to connect your display.

Note: Cactus Micro works at 3.3V. Please check the voltage for LCD.

This might be my stupidity, but when i use the correct pinout from the Rev2 i can’t find pin nr 12 11 as mentioned in the tutorial.liquidcristal

I am using thins pinout

Kind regards,


Please note: you are playing Cactus Micro not Arduino UNO. They have difference pinouts. You can just try other digital pins on Cactus Micro.
