Other key parts include the MCP73831-2ACI/OT, AP2112K-3.3TRG1 and USBLC6-2SC6. By type, the board carries 60 switches, 60 diodes, 7 capacitors, 6 resistors, 4 connectors and 3 ICs.

It belongs with the keyboards and dev boards & breakouts designs in this gallery.

From the project

59-key hot-swap mechanical keyboard PCB carrier for a socketed ESP32-C6-DevKitC-1 dev board — KiCad project generated/routed by Python scripts

59-key (5×12, bottom row 5 + 2U + 5) hot-swap low-profile keyboard carrier board — the same physical key layout, switch/socket footprint, and power system as the sibling ~/esp/SMKKeyboard/smkkbd project, but instead of a soldered-down ESP32-C6-MINI-1 module, this board takes a removable Espressif ESP32-C6-DevKitC-1 dev board plugged into two female headers on the back.
