Help with building HmIP-MOD-OC8

you are right :frowning: I think that TX and RX seamed to be mixed as well. Lets move that to the topic: Bugs in Arduino Nano Every Fritzing part v6
So others might find that and its not in my thread … By the way I´m currently on the way to fix some of the issues I saw (because I need that in my PCB). Should take me a hour, then i will update the posting in the URL below with my version. Maybe you can do a quick check then.
