Keyboard Builders' Digest / Projects
Peregrine ZH
Modular low profile ergo keyboard by SouthPawEngineer with built-in USB hub.
Published August 4, 2021
This particular keyboard is a derivative of the Peregrine keyboard (although that keyboard is wireless and this one, the Peregrine ZH, is not).
The keyboard itself features a set of 5-way switches that are directly accessible for use by the thumb. There is also a rocker switch and two encoders that can be used for navigation or media functions.
The other unique thing about this keyboard is that it uses magnets to hold the center add-on board in place.
There are a few extra MCU pins broken out (I2C and analog pins) so that you can use things like an OLED display. However, the real neat part here is that one of the on-board USB hub's ports is connected to one of the modular connector ports. This means that the add-on module can be an entirely separate USB device that is capable of being individually programmed. This makes it easier to keep the keymaps that you like, while making it easier and faster to integrate new add-on module functionality.
It also means that a single keyboard could be running some combination of ZMK, QMK, CircuitPython, Arduino, or whatever your favourite way to code and interact with electronics is - all concurrently, all at the same time – SouthPawEngineer.
