Overview
Macropad is an open-source printed circuit board by bulviakas, from the bulviakas/everything-pad repository on GitHub, published under the MIT licence. It is a 2-layer board of 90 × 68 mm with 26 parts on 29 nets, routed with 199 tracks and 28 vias.
It is built around the SK6812MINI-E and WS2812B. Its parts include 15 diodes, 7 switches, 1 IC and 1 connector. It belongs with the keyboards and input and lEDs and displays boards and the RP2040 boards of this library.

README
README.mdEverything pad - Custom macropad
A macropad project for the Blueprint program by Hack Club.
The mini-keyboard features:
- 6 programmable keys
- Rotary encoder
- 8 RGB LEDs for backlight
- OLED display
Designed to be a helpful tool while editing, gaming or just deep in flow state. The main goal - versatility: multiple modes for every needed occasion (system sound control, application shortcuts, backlight configuration).
Tools
- PCB: Custom-designed using KiCad
- Case: Modeled in SolidWorks
- Firmware: Built with QMK, supporting multiple layers, RGB lighting, encoder input, and OLED display
Status
(2026-03-31) Project still in progress - no physical testing yet!
PCB
Schematic view
The keys and the rotary encoder are connected in a matrix.
The product itself
A personal character Steve was made with Inkscape. Everyting is connected over 2 layers, with 0.4mm traces and GND fields. SK6812-MINI-E LED footprints were modified due to clearance errors.
CAD model
The assembly process is quite simple - the PCB is mounted onto the bottom part of the case with 2 M3 bolts and heatset inserts. Top cover just slides in from the top.
Firmware
As of now, the code is purely theoretical, since there is no way to test it. However, in theory, the keyboard has 3 modes:
- System sound control - play/pause music, increase/decrease volume, mute, etc.
- Application shortcuts - case-specific keybinds, eg. Discord toggle mute, toggle camera
- RBG backlight configuration - increase/decrease brightness, hue, etc.
The colour of the RBG backlight shows the currently active mode (SSC - Blue, Apps - Green, etc.). OLED display serves as the main info output when switching modes. Since the macropad cannot read real system sound values, it stores simulated volume and displays a simple bar on-screen when relevant.
BOM
A list of everything used to make this masterpiece:
- 1x Seeed XIAO RP2040
- 7x through-hole 1N4148 Diodes
- 6x MX-Style switches
- 1x EC11 Rotary encoder
- 1x 0.91 inch OLED display (GND-VCC-SCL-SDA)
- 6x white blank DSA keycaps
- 8x SK6812 MINI-E LEDs
- 2x M3x16mm screws
- 2x M3x5mx4mm heatset inserts
- 1x case (2 printed parts)
- 1x printed knob for the encoder
- Some joy and whimsy~

Questions
How big is the Macropad PCB?
It measures 90 × 68 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
26 parts, built around the SK6812MINI-E and WS2812B. 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 bulviakas/everything-pad 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 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).
