README
README.mdEpicMacroPad
A simple macro pad consisting of 4 MX Switches, a Rotary Encoder, and an OLED Display. It uses QMK firmware and implements a few common macros that can be customized with code. Also, my first ever project!
Components:
- An EC11 Rotary Encoder that is used to control volume, brightness, etc.
- A 128x32 OLED Display for information or other fun animations.
- 4 MX Switches that run certain macros and functions.
PCB:
PCB was designed in KiCAD.
PCB:
Schematic:
CAD/CASE:
I made a case for the macro pad in Fusion 360. The case has three main parts: a bottom base, a plate, and a top cover.
Firmware and Functions:
The four switches perform functions such as Copy, Paste, and taking a Screenshot. Additionally, pressing down on one of the switches changes the layer, allowing for a greater range of functions.
The rotary encoder controls volume by twisting it.
BOM:
- 1x Seeeduino XIAO RP2040
- 4x MX Switches
- 1x EC11 Rotary Encoders
- 1x 0.91" OLED Display
- 4x M3x16mm screws

Questions
How big is the HackPadAryan PCB?
It measures 95 × 63.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HackPadAryan use?
9 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 HackPadAryan KiCad files?
From the epicninja3/EpicMacroPad repository on GitHub, at the commit this page was made from: the board is PCB/HackPadAryan.kicad_pcb and its schematic PCB/HackPadAryan.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HackPadAryan design in my own project?
Its repository states no licence, so its author keeps all rights: ask epicninja3 before reusing the design.
