Overview
Gov is an open-source printed circuit board by Chiron8, from the Chiron8/LitePad repository on GitHub. It is a 2-layer board of 91.5 × 88.2 mm with 16 parts on 20 nets, routed with 162 tracks and 0 vias.
It is built around the SK6812MINI-E. Its parts include 7 diodes, 7 switches and 2 ICs. It belongs with the keyboards and input and lEDs and displays boards of this library.
Main components
1README
README.mdLitePad!
LitePad is a 6 key, 2x3 keypad with a rotary encoder, OLED display and an RGB LED using QMK firmware. The aim for this project is to create a simple macropad to control govee smart LED bulbs via a host PC!
Features
- Awesome case!
- 128x32 OLED Display
- EC11 Rotary Encoder
- 1 WS2812B RGB LED
- 6 Keys
CAD Model
Uses 4 M3 Screws to hold the two parts of the case together. The PCB is placed inside the case with a cutout for every component and USB port.
PCB
Awesomesauce PCB. Sorry for the black line in the screenshots.
Firmware
Currently unfinished as I am new to QMK. I will soon add features to communicate with a host PC with serial which will then control the govee lights. Currently it sits around and does nothing.
What do you need to make this keypad thingy
- 6x Cherry MX switches
- 6x DSA Keycaps
- 4x M3 16mm bolts
- 6x 1N4148 Diodes
- 1x WS2812B LED
- 1x 0.91" 128x32 OLED Display
- 1x EC11 Rotary Encoder
- 1x XIAO RP2040
- 1x Case (1x Bottom part, 1x Top part)
- Some love <3
Extras
Thank you to Hack Club for being awesome and supporting me :) (Also I need work experience...)

Questions
How big is the Gov PCB?
It measures 91.5 × 88.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gov use?
16 parts, built around the SK6812MINI-E. 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 Gov KiCad files?
From the Chiron8/LitePad repository on GitHub, at the commit this page was made from: the board is PCB/gov.kicad_pcb and its schematic PCB/gov.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gov design in my own project?
Its repository states no licence, so its author keeps all rights: ask Chiron8 before reusing the design.
