58-key split low-profile keyboard with optional touchpad and rollers: configuration, connection, remapping and care.
Last updated 2026-10-15
MIX is a 58-key split low-profile keyboard with Kailh Choc V2 switches in hot-swap sockets, an optional Cirque touchpad and metal rollers. It runs QMK (Vial), ZMK or RMK.

Configuration
MIX is a DIY keyboard, so you choose the configuration when you order. None of these options change the price:
- Roller: left, right, both or none. Each half has up to 30 key positions and a roller takes the place of 2. The standard build has one roller on the right: 58 keys (30 left + 28 right).
- Touchpad: with or without.
- Firmware: QMK or ZMK with the touchpad; QMK, ZMK or RMK without it.
Quick start
- Check the box contents: Coming soon
- Connect the keyboard with a data-capable USB-C cable.
- Open any text editor and test every key.
Connection
How MIX connects depends on the firmware:
| Firmware | To the computer | Between halves | Central half |
|---|---|---|---|
| QMK (Vial) | USB-C wired | USB-C to USB-C cable | Either (the one plugged in) |
| ZMK | Bluetooth or USB-C wired | Wireless | Right with touchpad; left without |
| RMK | Bluetooth or USB-C wired | Wireless | Left (RMK is touchpad-free only) |
For wireless builds, see Bluetooth pairing.
Charging and battery
Only the ZMK and RMK wireless builds use the batteries:
- Each half has a 1500 mAh battery that lasts about 1–2 months per charge.
- Charge with a standard 5 V 1 A charger. Fast charging isn't supported.

Remapping
