Overview
MIDI Keypad is an open-source printed circuit board by GIvemefreecopilotmax, from the GIvemefreecopilotmax/MIDI-Keypad repository on GitHub. It is a 2-layer board of 70 × 95.1 mm with 5 parts on 20 nets, routed with 162 tracks and 0 vias.
Its parts include 1 IC, 1 connector and 1 switch. It belongs with the keyboards and input and audio and music boards and the ESP32 boards of this library.
README
README.mdMIDI Keypad
My custom MIDI keypad project, designed in KiCad using a Waveshare ESP32-S3-Zero.
Features
- Seven capacitive touch keys
- Two sliding potentiometers
- One rotary encoder
- USB connection through the microcontroller
The keypad is intended to send MIDI notes and control messages once the firmware is implemented.

Current progress
The schematic and PCB layout have been created. Firmware, physical assembly, and hardware testing are still pending. Manufacturing files still need final verification.

Questions
How big is the MIDI Keypad PCB?
It measures 70 × 95.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MIDI Keypad use?
5 parts. 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.
Where can I download the MIDI Keypad KiCad files?
From the GIvemefreecopilotmax/MIDI-Keypad repository on GitHub, at the commit this page was made from: the board is MIDI-KEYPAD.kicad_pcb and its schematic MIDI-KEYPAD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MIDI Keypad design in my own project?
Its repository states no licence, so its author keeps all rights: ask GIvemefreecopilotmax before reusing the design.
