Glacier One is a macropad designed to go along with the Phendrana Keyboard. Deriving it's name from a research center in Metroid Prime, located in Phendrana Drifts, the macropad aims to reach a similar goal, researching the circuit to ensure it works correctly before buying the full Phendrana Keyboard. It uses a Makerdiary nrf52840 m.2 board, so it is easily able to be swapped out if broken.
Features
- Longer Battery Life
- Multiple Bluetooth Connections
- Single-colour Backlight
- Cherry MX and Kailh Choc compatible
- Swappable Switches, Battery, and MCU
- 3D Printed Case
- 3DS Joystick
- OLED
Firmware

To compile the firmware:
⚠ Under Construction: ⚠
Hardware
Currently the Hardware files are not released. The 3d case files are intended to be released at one point, however I wish to fix the files first, and provide more files for different versions of Glacier One.
KiCAD/Gerber files likely won't be released, and neither would the BOM. This is because it wasn't really designed to be built by others, and I'd want to do a complete overhaul if others were to build one. If you'd like Glacier One, contact me
Versions
Rev 1.0.0 - Initial Release - Small errors, and doesn't include the voltage dropout detector in the PCB. Initial versions have been fixed with flywires
Instructions
Instructions for this project are not available.
Can I buy this?
Similar to Phendrana, a few Glacier One's have been given to friends, from extra parts I had when making my own. I do not really intend to sell these.
If you would like parts, feel free to get in contact. Please note that lead times may be long (likely about a month, I need to get parts and time for assembly), and are subject to price changes.
Notes
Glacier One is a keypad that attempts to follow the ZMK design language. This introduces a few unique features to the board, that may be odd the first time used. These are:
- Power, there is no outside power switch for Glacier One, it relies on sleep modes to save power
- Internally there is a power switch, however it was designed as more of a power switch for long transport
- Glacier One has two sleep modes:
- Idle - LEDs turn off, keyboard is still connected (~30s after you've stopped typing)
- Sleep - Keyboard disconnects from devices to save power from Bluetooth (~15m after you've stopped typing)
- These timings can be changed in the .conf files (for left and right), using these parameters: https://zmk.dev/docs/config/power#idlesleep
- Glacier One can be used either through USB, or Bluetooth, if connected to a PC using USB, it will always send keystrokes to the PC through USB
- You should still be able to charge while using Bluetooth, you just would need to use an AC adapter to do so
- It should be noted that Glacier One won't work with USB C-C cables
