This project is a custom 11-key mechanical macropad built using the Seeeduino XIAO RP2040 microcontroller and Cherry MX switches. The device primarily functions as a numpad, but it can also transform into a programmable macropad when certain keys are held. By holding the 0 and 1 keys the device switches software profiles and changes what the keys do from a regular numpad to a macropad. To use the macropad, simply plug it into your computer using a USB-C cable. The device will automatically be recognized as a keyboard. In its default mode, the keys act as a numeric keypad. Holding the 0 and 1 keys at the same time activates the macro profile, allowing the keys to trigger custom macros depending on the firmware configuration. I created this project to design a compact keypad that could serve both as a numpad and a programmable macro controller. Many keyboards (such as mine) do not include a numpad, and having an additional macro layer makes repetitive computer tasks faster and more convenient. This project was also a way to learn PCB design, CAD modeling, and firmware development for custom hardware. This design was reviewed and sanity-checked with peers to verify component placement and wiring before fabrication.
