Title: caps lock led support to a non led pcb QMK
Post by: rjohn on Sat, 17 December 2022, 09:11:18

Hello

i totaly new in pcb moding and i have a question ,if its possible to manual add a caps lock led (custom wiring)  and be able to make it work if you program it with QMK.

i am talking about the Plain60-C rev2 pcb.

I've just had a look in the firmware (https://github.com/qmk/qmk_firmware/blob/master/keyboards/evyd13/plain60/config.h) and at the PCB and it's almost like they want you to add an LED because pin B0 is not used but looks to be connected to a hole just below the controller chip, alongside 5v and ground connections. 

Go for it :)

It's a good first mod and you're not going to break anything - if the firmware doesn't work you just change it and try again.  I'm interested to see how/where you mount it so please post some pics when you're done :)
