Jack-Jacobson/CustomMacroPadLearning PCB and electronic creation through making a bluetooth macropad!
CustomMacroPad is an open-source printed circuit board by Jack-Jacobson, from the Jack-Jacobson/CustomMacroPad repository on GitHub. It is a 2-layer board of 114.3 × 76.2 mm with 10 parts on 19 nets, routed with 145 tracks and 0 vias.
It is built around the ESP32-C3-DEVKITM-1. Its parts include 9 switches and 1 IC. It belongs with the keyboards and input boards and the ESP32 and RISC-V boards of this library.
This is a 9-key macropad with an ESP32C3 dev module at it's core. It will be able to play, pause, control volume, skip, and have programmable macro keys.
This project was intended to help me get into the hardware part of creation. I had to learn KiCad, CPP, and more to be able to make it. In the future I also plan on using these skills to make a full keyboard!

It measures 114.3 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
10 parts, built around the ESP32-C3-DEVKITM-1. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the Jack-Jacobson/CustomMacroPad repository on GitHub, at the commit this page was made from: the board is kicadFiles/project.kicad_pcb and its schematic kicadFiles/project.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Jack-Jacobson before reusing the design.
