Description
Custom Mechanical Keyboard
Mist is my take on a full size keyboard, but with some upgrades I carried over from my second keyboard build--Hermod. Furthermore, this is the UDB version of Mist, which stands for Unified Daughter Board
Aside from the UDB connector and the lack of USB-C/on-board ESD protection circuitry, this keyboard is functionally identical to the base Mist keyboard.
Features
- 2.2" LCD Display: A 2.2" LCD Display to show keyboard state, stats, and any fun animations I can think of.
- Thumb Clusters in Place of Spacebar: I loved the thumb clusters from my split keyboard and the giant spacebar is such a waste of space!
- Connector for Unified Daughter Board: A Unified Daughter Board extracts all the ESD and over-voltage protection from the main PCB and allows for more complex case shapes.
- Per-Key RGB Lighting: Vibrant, individually addressable RGB LEDs for endless customization.
- KS-33 + MX/Gateron Normal Profile Hot-Swappable Switch Sockets: Support for either KS-33 low-profile or MX style (Cherry or Gateron Normal profile) switches.
- QMK Firmware: Fully programmable and customizable using QMK.
- Standard QWERTY Layout and Keymap: The layout we all grew up learning to type on!
Specifications
- Microcontroller: STM32G474RETx
- Display: 2.2" LCD (320x240 resolution) per half.
- Lighting: SK6812 Mini RGB LEDs.
