Corn Electronics GK21 Kit Red Switch White

The Corn Electronics GK21 Kit is a compact mechanical keyboard kit featuring Red linear switches and a white finish. It targets enthusiasts who want a customisable typing platform with hot-swappable sockets and per-key RGB lighting.

Sustained use with 32-bit MCU and 8M Flash

A 32-bit MCU and built-in 8M Flash store three programmable layers and lighting profiles without software dependency. Bluetooth 5.1 and Type-C wired modes share the same 750 mAh battery, so extended wireless sessions do not force a recharge mid-task.

Hot-swappable Kailh sockets

Hot-pluggable Kailh connectors accept three-pin or five-pin MX-style switches from Cherry, BOX or Gateron families without soldering. The PCB supports plate-mount stabilisers only; builders using PCB-mount stabilisers will need a different plate or modification.

Questions about this item

How loud and warm does the GK21 Kit run when used all day?

The hot-swappable Red Switches are linear and quiet, and the 32-bit MCU with 8M Flash draws little power, so the board stays cool and silent during extended sessions.

What must I already own to assemble the GK21 Kit?

You need a plate, stabilisers, keycaps and a case; the kit supplies only the PCB, Red Switches, 16.8M RGB LEDs and a 750mAh battery.

Can the GK21 Kit connect to an older PC without Bluetooth 5.1?

Yes, the Type-C USB cable provides a wired link that works with any USB port, while Bluetooth 5.1 is optional for wireless use.
