Overview
Macro pad is an open-source printed circuit board by L0G24, from the L0G24/Macro-pad repository on GitHub. It is a 2-layer board of 85.1 × 50.1 mm with 13 parts on 19 nets, routed with 84 tracks and 2 vias.
Its parts include 6 switches, 5 diodes and 2 ICs. It belongs with the keyboards and input boards and the RP2040 boards of this library.
README
README.mdMacropad — Volume + Macro Controller
This is my custom macropad built for Hack Club Blueprint.
It’s a small desk controller that lets me:
-
Control volume with a rotary encoder
-
Play / pause with encoder press
-
Use shortcut keys (Chrome, Copy, Paste, LED mode, minimize app)
-
Show animations + volume on an OLED
-
Control RGB effects with presets using one of the keys
I designed the PCB in KiCad, modeled the case in Fusion, and programmed it using KMK.

Questions
How big is the Macro pad PCB?
It measures 85.1 × 50.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macro pad use?
13 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 Macro pad KiCad files?
From the L0G24/Macro-pad repository on GitHub, at the commit this page was made from: the board is PCB/macro pad.kicad_pcb and its schematic PCB/macro pad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macro pad design in my own project?
Its repository states no licence, so its author keeps all rights: ask L0G24 before reusing the design.
