So how is this better/different than an off-the-shelf keyboard?
- Mechanical switches, but that's not that special of course.
- Low-profile, which is much rarer. You can (finally) buy some low-profile mechanical keyboards, but the have this extra height from the case and key caps. This one is as thin as possible, just the lowest key caps, the low-profile switches, the PCB and some rubberized stickers for good grip.
- Ortholinear, which already makes it unique. As far as I can tell, there are currently no low-profile ortholinear keyboards you can buy.
- One-piece split layout. For that sweet ergonomy.
- Narrow, for easy access to all keys without moving your hands.
- Now with a number row.
- Programmed with CircuitPython, for easy customization.
Otherwise there isn't much experimental stuff going on in here, like in my previous keyboard projects. In fact, I simply took what I learned from them, and applied it in the simplest way possible.
