Knox's Hackpad 2.0

I started component placement and ran into a problem about the amount of space because I am pretty sure I am limited to 100x100mm and currently I am like 300x200. Finished the 3d model of components.

I finished the schematic and also added sliders and added capacitors for the lights and sliders. Might need some more room for the pcb because 100x100 will probably not be enough. Ran into a problem when assigning footprints because I have these external pins so in the future I could add other things but I couldn’t find it but then I changed one character when looking it up and it worked.😅

I changed my plan into doing 21 switches, and 3 Rotary encoders, Lights, and added some external connectors so that in the future I could add more if needed. I relized at the end that I might need 0.1uF capacitors for each light and I am going to ask slack after I post this.

I started working on the schemadic and ran in to a problem with the Xiao RP2040 because of its limited gpio pins and decided to add a MCP23017 in order to be able to use 16 switches, 1 screen, and 2 rotary encoders. The reason I am going with this is because I want to make a really cool mixing board for dj things.
