This is a simple 3-key macropad built with a Seeed Studio XIAO RP2040 and Cherry MX compatible switches. It is designed as a compact beginner hackpad with a clean PCB layout and a custom case. The project focuses on the essential parts of a macropad: a small PCB, three programmable keys, and firmware that can be customized for shortcuts or macros.
8-bit combinational ALU built from scratch with 3,488 CMOS transistors (KiCad + SPICE + Logisim + 1.24M tests
