69split - my split keyboard with broken out IO for project development
Hey guys! I'm really proud to share the first version of my keyboard. The point of the keyboard is to break out the IO of the ATmega32u4 so that it can be used when developing other projects, while also having it be a keyboard! It is split of course with an MCP23017 on the right side. No problems so far and I'm very happy with it. The next version will definitely look a bit different. Need to get new parts since those USB connectors ruined my life fr.
The inspiration for it (other than the fact that I wanted a cheap split keyboard with QWERTY), was that during project development you may need a GPIO to go high or low to test another IC or a dev board. Well with this keyboard you can do that. The software for it needs some tweaks still but it's at a very good stage currently.
I hope you also like the DIY aesthetic on the keycaps. That is also intentional since I don't want to have to buy expensive keycap sets for it. The plan is to just write over them like that which I really like.
Any feedback or questions are very welcome!
