Overview
Silas Keypad is an open-source printed circuit board by sbunger, from the sbunger/Silas-Keypad repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 80 × 66 mm with 19 parts on 24 nets, routed with 86 tracks and 0 vias.
It is built around the SK6812MINI-E. Its parts include 10 diodes, 8 switches and 1 IC. It belongs with the keyboards and input boards and the RP2040 boards of this library.

README.mdSILAS' KEYPAD
Silas' hackpad project created with help from Hackclub! This macropad has eight keys that are currently programmed to control browser and copy/paste functions, but can be programmed with other keys and even macros. The pad runs on an RP2040 devboard by Seeed Studio. The PCBs were created in KICAD and the CAD files were made in Fusion. I used the KMK library to program my keyboard.
I created this macropad to gain experience in electronics while making something cool that I will actually use. Currently, the keys are as follows from left to right: Row 1: Copy, Paste, Cut, Ctrl-Alt-Del; Row 2: New Tab, Close Tab, Reopen Closed Tab, and new firefox window (requires custom shortcut on windows).
Bill of Materials
- 8x M3x5mx4mm heatset inserts
- 8x M3x16mm screws
- 2x SK6812 MINI-E LEDs
- 8x Cherry MX Switches (Or equivilant)
- 8x Blank DSA keycaps
- 8x Through-hole 1N4148 Diodes
- 1x 3d Printed Case (Self Printing)
- 1x Manufactured PCB
- 1x Seeed XIAO RP2040
Cad
All cad was created in Fusion 360 Education. I really enjoyed using bevels on the edges to make it feel truely polished. All holes in the base will be fitted with threaded inserts and the holes will use M3 nuts and bolts.
PCB
PCBs were created in KICAD.
Renders
Renders were created in Fusion and Blender.

Questions
How big is the Silas Keypad PCB?
It measures 80 × 66 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Silas Keypad use?
19 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 Silas Keypad KiCad files?
From the sbunger/Silas-Keypad repository on GitHub, at the commit this page was made from: the board is PCB/pcb.kicad_pcb and its schematic PCB/pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Silas Keypad design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
