From the project

The Ergo Little Guy - A small split-design keyboard

The Spacetime is a ~36% split ortho-linear keyboard based on the Half n Half, ErgoDox and Helix. It has a tripple thumb cluster and an optional palm key. The palm key can be broken off and not used at all if you don't want it.

Currently being shipped some prototypes and I will probably have some bugs to work out. After that I will need to add more silk screen and I need to create jumper pads to support the OLED that can go over the microcontroller.
