Most DIY macropads I could find on the internet were either too expensive or had too many features for my needs (knobs, displays, etc).

My goals were as follows:

Easy to Program
Cheap to make
Beginner-friendly soldering and 3D printing
No larger than a numpad

###Processor

I chose the Seeed XIAO RP2040 for its size, IO, and price. A single board is available for less than $10 in the US, and has exactly the number of GPIO pins needed for this project. The XIAO is also able to be soldered with castellated holes for a low profile.

###Keyswitches

I designed this to be compatible with Cherry MX 3 and 5 pin models. These are easily accessible in packs of 10 or more.

##Circuit Board

I designed the circuit board with KiCAD and had them manufactured through OSHPark and JLCPCB. It is a du
