Question any good guides on making custom circuit boards and scripting for the raspberry pi pico?

[Linx87]

Working on connecting a raspberry pi pico to a gc+ so i can send inputs from parsec to my wii for playing gamecube games online on actual hardware.
On the circuit board side, it would just be for making the connections between the inputs on the gc+ and the pico's gpio plus the gamecube plug.
On the scripting side it will take inputs from parsec's virtual controllers and tell the pico to send a signal from the gpio to the gc+.
(i`ll probably make an actual worklog too once i get the parts)

Get familiar with KiCad, start with schematic builder because it'll be a lot easier than actually figuring out trace widths and stuff like that, and then move to pcb builder, make sure you're double-checking sizes of caps and resistors before you select (I was burned by having a whole board of place holder parts then getting ot the final stage and realising what I'd done.
