Hello everyone!
I love the cheap Pro Micro to do custom keyboards.
But it only have 18 pins. I've done many keyboards in 5x13 matrix (65 keys), but I was wondering is "something" (electronical I guess) prevent me to use it as a 9x9 matrix to have more keys (81 keys) even if wire is more difficult.
TL;DR: Can I use a use a 9x9 matrix on Pro Micro to build 81 keys keyboard?
A big thanks in advance!
Is a 9x9 keyboard technically doable on Pro Micro?

Thanks, I still need one last info. If I unsold the two vertical resistors, each one have two holes (one coming from the LED and the second from the other part of the circuit).
On my picture, which numbers would be the "new" pins? 1 and 3 or 2 and 4?
A big thanks in advance!

Haha. Sorry mate not familiar with circuit diagrams. I am a complete noob on the things and was totally winging it when I build my board.
But anyway you’re correct its 2 and 4. Lastly, just checked my board and it tirns out I didn’t even removed it (really remembered I did).

Suggestion - get yourself some UV-cured PCB mask. That hot-glue isn't going to protect the connection fully from stress.
