| 12 pin headers and sockets | 4 | You can use through-hole diode legs as pins. Sockets spacing: 2.54mm, Socket height: Using minimal height sockets might not leave enough room to mount the battery under the MCU. 3DS1002-01-1*20V13-JK by CONNFLY are a good choice, but you can also use lower ones and longer legs instead. Spiltkb has a good [guide on mounting](https://docs.splitkb.com/hc/en-us/articles/360011263059). |

## TODO List
|
|
- [ ] Increase diode-socket distance.
|
|
- [ ] Fix MCU pin labels on right-front (Some are mirrored / not on the correct side of the MCU).
|
|
- [ ] Give this project a **name**.
|
|
- [ ] Use github actions to build + release gerber files.

## Standing on the shoulders of giants

|
|
- A great tutorial I referenced a lot by FlatFootFox: https://flatfootfox.com/ergogen-introduction/
|
|
- Lots of inspiration and ideas for this project came from these boards: [Choccy](https://github.com/sprengboard/choccy), [Sofle](https://github.com/josefadamcik/SofleKeyboard), [brain](https://github.com/Wesztman/brain), [spleeb](https://github.com/chrishoage/spleeb)
