Visorbearer keyboard

Visorbearer

Visorbearer is a 32-key unibody split wireless keyboard featuring 8 RGB LED indicators.

Named after hummingbirds in the genus Augastes for the Hummingbird layout connection and distinctive white bands on their chests that resemble the LED indicators.

[!WARNING] This is a work in progress.

Design

https://github.com/user-attachments/assets/812049e3-29ce-48d4-8fe3-20bf21285e64

  • 2x 4-segment RGB LED indicators

    • Discreet dead-front design: completely invisible when off
    • Connection bar: Bluetooth profiles and modifier keys
    • Battery bar: percentage and charging status
    • Powered by two TI LP5012 drivers with automatic low-power mode
  • 32-key Hummingbird-ish layout with splay and inverted thumb cluster

    • Down to 26-key with case and plate variants
      • 2U thumb key support
  • Hot-swap Kailh Choc v1 switches in Choc (18x17mm) spacing

    • The PCB is incompatible with older Choc v2 switches that have a third stabilizing pin. Newer Choc v2 releases without this pin work fine, such as: Lofree POM Phantom/Ghost/Specter/Hades and Kailh Hide Mountain/White Rain/Deep Sea Mini Islet/Deep Sea Mini Whale.

      Note that, for Choc v2, there are very few off-the-shelf options for choc-spaced keycaps with MX stems: as of late 2025, the only two are Taihao THCS and Asymplex MX-stem Chicago Steno. You could also 3D-print your own keycaps.

  • Seeed Studio XIAO nRF52840 Plus controller on ZMK firmware

  • 3D-printed case and switch plate with switch puller grooves

    • Easily accessible reset button
