Overview
CodePad is an open-source printed circuit board by sevinatenine, from the sevinatenine/CodePad repository on GitHub. It is a 2-layer board of 60 × 80 mm with 16 parts on 14 nets, routed with 57 tracks and 0 vias.
Its parts include 7 switches, 4 connectors and 1 IC.
README
README.mdCodePad
CodePad is a custom hack pad (macro pad) with 6 keys, a rotary encoder and a screen! I designed this project for the Stardance Hackpad mission.
Features
- 128x32 OLED Display
- EC11 Rotary encoder (for volume/anything)
- 6 Cherry MX-style keys
CAD
CodePad is printed in two pieces, the lid and the case. There are 4 screws that go through the lid, sqeeze down the pcb and go into threaded inserts in the bottom case. You will need 4 M3 bolts and the threaded inserts for them. This was made in Fusion360.
PCB
The PCB was made in KiCad. I added a ground plane.
Firmware
I have not wrote the firmware yet and I will when my PCB arrives from JclPcb. When I do, I will probably use QMK. I also want to include a virtual pet on the screen and make it wake and sleep based on if you are typing or not.
BOM
- 6x Cherry MX Switches (~$0.96)
- 6x DSA Keycaps (~$2.25)
- 1x 0.91" 128x32 OLED Display (~$7.99)
- 1x EC11 Rotary Encoder (~$1.00)
- 1x XIAO RP2040 (~$3.99)
- 4x M3 bolts (~$0.07)
- 4x M3 heat-set threaded inserts (~$0.26)
- 1x Case (2 3D printed parts) (Print the case and lid).
- 1x PCB (2 layer) (The gerbers are here). Can be manufactured by a company such as JLCPCB (~$2.00).
Estimated total: ~$18.52 (prorated from multi-packs, so you'll actually pay more up front for the full packs).

Questions
How big is the CodePad PCB?
It measures 60 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CodePad use?
16 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 CodePad KiCad files?
From the sevinatenine/CodePad repository on GitHub, at the commit this page was made from: the board is pcb/CodePad.kicad_pcb and its schematic pcb/CodePad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CodePad design in my own project?
Its repository states no licence, so its author keeps all rights: ask sevinatenine before reusing the design.
