README
README.mdMacro Pad
A 12-key macro pad with a configurable rotary encoder and OLED display, built around the RP2354A microcontroller and custom MicroPython firmware. Fully programmable through a web-based configurator.
How to Use
Plug the Macro Pad into your Windows, Linux, or macOS device using a USB-C data cable, then go to the Installation Website and follow the steps to install (or update) the Macro Pad firmware. This requires a browser that supports Web Serial (Chrome, Edge, Opera, or Firefox), Safari isn't supported.
The OLED display shows the current layer and the function assigned to each key. Press and hold the rotary encoder button to switch layers.
To configure the device (adding, editing, or deleting layers) visit the Macro Pad Programmer.
Coming Soon
- A Windows app that will allow you to update and configure settings for the Macro Pad.
Why I Made This
I built this project to create a fully customisable and open-sourced macro pad. It has also served as a way to develop my skills in schematic design, PCB layout, and 3D Modelling.

Questions
How big is the Macro Pad PCB?
It measures 112 × 70.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macro Pad use?
50 parts, built around the RP2354A, PEC11R-4225F-S0024 and ABM8-272-T3. 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 Jpwaters09/Macro-Pad repository on GitHub, at the commit this page was made from: the board is PCB Files/Macro Pad.kicad_pcb and its schematic PCB Files/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 publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
