Made the schematic for my 3x4 button macropad and added led’s to go under the switches as well as a rotary encoder. I was planning on doing a 4x4 macropad with oled and rotary encoder but the MCU doesn’t have enough pins for that so I decided to go with 3x4 + rotary encoder + LEDs. I also assigned the footprints for the PCB but I haven’t started laying out the PCB yet. I am not sure where to place the diodes or LED’s so if you know please let me know in the comments (I want one LED under each switch and need the diodes for the matrix layout).
