Overview
Macropad is an open-source printed circuit board by AccelRanger, from the AccelRanger/macropad repository on GitHub, published under the Apache-2.0 licence. It is a 2-layer board of 60 × 70.3 mm with 46 parts on 48 nets, routed with 339 tracks and 21 vias.
It is built around the ESP32-C6-MINI-1. Its parts include 9 diodes, 9 switches, 7 capacitors, 6 resistors and 2 ICs. It belongs with the keyboards and input boards and the ESP32 and RISC-V boards of this library.

Custom macropad with a custom PCB and firmware.
How it works
The firmware running on the ESP32-C6-1M sends button-number data to the software running on the computer.
The computer-side software processes the received data and emulates keyboard input based on the presets configured on the computer.
Hardware
-
Microcontroller: ESP32-C6-1M
-
Button layout: 3 rows × 3 columns
-
Total buttons: 9
-
PCB: Custom-designed PCB
Planned features
- Bash commands
Signal flow
- A button is pressed on the macropad.
- The ESP32 firmware identifies the button and sends its number to the computer.
- The computer-side software receives the signal.
- The software checks the active preset for that button's binding.
- The software sends the configured keyboard input.
Project status
This document describes the intended design and features.

Questions
How big is the Macropad PCB?
It measures 60 × 70.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
46 parts, built around the ESP32-C6-MINI-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.
Where can I download the Macropad KiCad files?
From the AccelRanger/macropad repository on GitHub, at the commit this page was made from: the board is PCB/macropad.kicad_pcb and its schematic PCB/macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
