Corne Wireless SMT PCB – Assembled Hot-Swap, ZMK Compatible

The wireless Corne you actually want to build has arrived!

Corne Wireless SMT is a fully assembled, hot-swappable PCB for the Corne / CRKBD layout. It ships pre-flashed with ZMK (ZMK Studio Ready) and requires no soldering, no TRRS cable between halves, and no firmware setup. Drop it in a compatible case, add switches and keycaps, pair, and type.

Whether you are looking for a reliable Wireless Corne or a drop-in wireless upgrade for your existing case, this PCB delivers a premium, cable-free experience.

Why This Board?

  • Zero soldering: Factory-assembled with hot-swap sockets.
  • True cable-free halves: Wireless between halves. No TRRS.
  • ZMK pre-flashed: Ready for pairing and live remapping in ZMK Studio.
  • Universal switch support: MX, Choc v1, and Choc v2 on one PCB.
  • Case friendly: Works with Unicorne and most standard Corne cases.
  • Expandable: 8-pin header for screens and peripherals.

Key Features Hot-swap sockets: Build and iterate without touching a soldering iron.

Frequently Asked Questions

Is the Corne Wireless SMT PCB fully assembled?

Yes. It’s a fully assembled, hot-swap wireless Corne / CRKBD PCB with the microcontroller, wireless module, and sockets pre-installed. No soldering required.

What firmware does it use?

It ships pre-flashed with ZMK and works with ZMK Studio for real-time keymap changes—ideal for a wireless split Corne build.

Will it fit my existing Corne case?

It works with Unicorne and most standard Corne cases, including many 3D-printed, FR4, and stacked acrylic designed. In order to use the PCB with a Unicorne, a Wireless Plate is required.

What batteries does the PCB support?

3.7 V LiPo packs via JST connector or the +/- solder pads. Typical max sizes: Choc ~30×17×3 mm, MX ~30×17×6 mm.

Which switches are supported?

MX, Choc v1, and Choc v2 on the same PCB. Spacing is always 19.05 mm.

Can I add a display?

Yes. An 8-pin header supports screens such as nice!view and other peripherals. VCC is switchable for power savings.

What is the pinout for the expansion header?

There is an 8-pin header on each side intended for screens (like nice!view) or other peripherals. The pinout from left to right is: 0.07, 0.21, 0.12, 0.23, VCC (Switched), GND, 0.19, 0.05. The VCC pin is controlled via GPIO pin 0.31 to save power.
