Before starting the design of the schematic, i did not know what i was signing up for. This is my first truly complex project on kicad, but i had gotten pretty used to the software by now.

I started by placing the Raspberry Pi pico 2 and my DAC, and wiring everything up. i then added a micro sd card slot, 8 push switches, a power switch, and a charging circuit (which i had to reference a real datasheet for! )

All in all, this was a very productive start to a project that lowkey might take over my life
