ROUND 3 This is the third hardware revision of the Woagboard keyboard. It's a 5x3 split ergonomic keyboard with 3 thumb keys on each half (36 keys total), inspired by the TOTEM.
I made this keyboard for myself, and to learn PCB design in the process. With the newest iteration, I've gotten into case design (Actually properly learning CAD for once), way more annoying part selection processes, and overall a chaotic time.
- 36 Keys
- 5x3 matrix, with 3 thumb keys on each half
- Splayed, column-staggered, ergonomic design
- Wireless, with generous space to fit a battery
- 400mAh should last you a month
- On-board MCU
- Nordic nRF52840, for BLE and USB-C connectivity
- Chaotic silkscreen printing
- Optional nice!view display mounting point
- RMK and ZMK firmware support
The case is designed to be 3D printed, with a focus on being thin, minimalistic, and clean. It features cutouts for all the necessary ports and buttons, and has a dedicated space for the nice!view display on the left half. It also features cutouts for Tenting Feet that make the keyboard way more comfy to use.
Silly, chaotic, yet somehow functional. The PCB is as small as the layout allows it to be, featuring an on-board Ebyte E73-2G4M08S1C module for wireless connectivity (Powered by the Nordic nRF52840), a BQ24075RGT battery charger (Which allows you to charge the keyboard while it's running. Such a revolutionary feature), and a 32.768kHz crystal for deep sleep functionality.
It also has really chaotic silkscreening. We stay silly.

This is the Bill of Materials (BOM) for 1 Woagboard (2 halves). This is why certain quanitites are doubled, as the board is two halves using the same PCB and components.

Notes:
- * Alternativelty, the Ebyte E73-2G4M08S1CX can be used for a UFL connector, requiring an external antenna. Both options annoyingly got moved to standard assembly only while I was making this design, increasing costs dramatically (~$60 -> ~$100). I've contacted JLCPCB about this, and hopefully I can get it back on economic assembly for anybody else trying to make this board.
- ** Typeractive also has these. If you're in the US, might be better to buy from them instead.
- I already have switches and keycaps, so I don't need to purchase them.
- I am not purchasing the nice!view for the fact that I'm out of budget if I do. Thanks JLCPCB.
The Woagboard is not affiliated with New Blood Interactive, Tour De Pizza, or any other IPs referenced on the design. I just like ULTRAKILL, Pizza Tower, etc.
