I liked the screwless design of Mr. Faruqi macropad, making easy to just put together.
I remixed the base so I could fit a YD-RP2040 and use the straight copper wire method to wire switches. I just made the slot for the board bigger and removed the 3.5 mm jack off the pad. This design is a little taller compared to the original as straight copper wire is taller then just soldering diodes together.
PINOUT:
GPIO 6-10: COLUMNS
GPIO 16-19: ROWS
SOFTWARE:
for rp2040's, I used POG from Jan Lunge. This allowed for easy creation of the mapping of the macropad. Here is my POG code and my Pins are the last image. Yours might differ from mine if you use different pinouts or diode directions.
