A s'mores themed macropad with 4 keys and a 0.91" OLED, powered by a XIAO ESP32-C3. The marshmallow keycaps (took apart from those popular toasted bread fidget keychains) and chocolate and graham-cracker inspired 3D printed make it a super cute accessory for fall. The XIAO's built-in USB-C is exposed on the side of the board for power and data.
Full build logs are in JOURNAL.md, and the parts list is in bom.csv.
