Osprey Keyboard Lets the nRF52840 Spread Its Wings

While most people don’t care whether they use one finger or ten, some people want to better themselves by learning how to touch-type. And honestly, there’s no easier way to do that than by getting into the ergo keyboard game. Even if you consider yourself a touch-typist already, an ortholinear or column-staggered keyboard may teach you otherwise, as you find yourself trying to type ‘c’ with your index finger (for example) and failing miserably.

[ebastler] chose the best of all routes and decided to build their own perfect keyboard, which is called the Osprey. It’s a wireless, column-staggered 40% that runs on ZMK firmware, which of course is open-source, as is the PCB itself and the thick and travel-ready printed enclosure. Although [ebastler] has yet to implement either one of these additional inputs, the Osprey also supports a thumbstick and a track pad.

Brain-wise, it’s a bare nRF52840 chip along with a TI BQ24075 for battery charging. The interesting thing about this implementation is that [ebastler] used and abused Nordic sample schematic #4, which utilizes both DC-DC converter stages of the chip. We can’t wait to see what this trailblazing build will mean for the community!
