Hi Everyone, first post on the forum so please forgive me if I’m asking in the wrong forum or breaking any rules I missed. I’m a complete noob so I might be asking a really silly question, but here goes
I’m currently designing my first custom board and will be using at least 77 keys. In order to keep the matrix simple and clean I would like to use an MCU that has enough pins to wire the rows and cols up without too much wire juggling.
The arrangement is 12 cols by 7 rows so just beyond what the trusty Pro Micro ATmega32U4 can handle with its 18 pins (without the LED mod to open up 2 additional). After some searching I found the Micro ATmega32U4-MU from RobotDyn which looks like it should be compatible, not too big and have enough pins for the project exposed.
Does anyone have any experience with this controller? Would it indeed be code compatible with qmk firmware?
