Redo everything and finnish pcb ooop
Forgot to journalโฆ oooop. So basically, I redid the schematic using an nRF module instead of the bare chip, because the bare chip was too much for me.
Finished schem:
Then I did the PCB layout and wired everything. Took some time, but it got really nice!

Redid the pcb and made it a matrix
Yesterday, while trying to wire everything, I realized that using a matrix would be way easier. So I switched to that and started rewiring my PCB. Itโs much cleaner now, and the matrix really helped.
And decided the edge cuts :yay:

It took me some time due to having to read quite alot of datasheets and some other things but i seems to be good before i even ship my project ill sanity check it like a few times
