Overview
Split keyboard STASIS is an open-source printed circuit board by anton2785-bit, from the anton2785-bit/Antons-Split-Keyboard-STASIS repository on GitHub. It is a 2-layer board of 207.4 × 138.7 mm with 96 parts on 72 nets, routed with 649 tracks and 51 vias.
It is built around the 1N4148W. Its parts include 40 switches, 38 diodes, 4 resistors, 4 connectors and 2 ICs. It belongs with the keyboards and input boards and the nRF52 and nRF5x boards of this library.

What is this project
- This is a split keyboard. That means that it has 2 separarate parts that are conected to the PC via bluethooth. This allows them to have separate layouts and to have the opportunity to be in different places whiie typing.
Why i made this project/split keyboard
- I wanted to have a small portable keyboard that I can still use for typing and to be compact.

Assembly
-
First I need to soulder everything to the PCB
-
Then I need to upload a test code that will let me see what switch is what signals.
-
Before it being done you need to put the now done assembly into the case.
-
After that I upload the real code and I am happy to use it afterwards.

Questions
How big is the Split keyboard STASIS PCB?
It measures 207.4 × 138.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Split keyboard STASIS use?
96 parts, built around the 1N4148W. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Split keyboard STASIS KiCad files?
From the anton2785-bit/Antons-Split-Keyboard-STASIS repository on GitHub, at the commit this page was made from: the board is PCB/Split keyboard STASIS.kicad_pcb and its schematic PCB/Split keyboard STASIS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Split keyboard STASIS design in my own project?
Its repository states no licence, so its author keeps all rights: ask anton2785-bit before reusing the design.
