Steps To Reproduce
- Order the PCB from whatever PCB manufacturer you like, download gerbers.zip from Production folder
- 3D print the case, Its in the production folder. Use whatever filament you want, probably PLA.
- Order the parts using the BOM ^^^
- Solder the parts onto the PCB
- Connect the LiPo battery to the PCB
- Flash your firmware/game onto it!
- Assemble case, sand the surfaces of top and bottom and then superglue or idk use tape. I didn't add screws for some reason.
- Press the button and play the game!

Questions
How big is the Tilt PCB?
It measures 49 × 59.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Tilt use?
17 parts, built around the HS96L03W2C03, SPX3819M5-L-1-8 and 1207-P6.5MM. 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 Tilt KiCad files?
From the Sealflux/Tilt repository on GitHub, at the commit this page was made from: the board is PCB/Tilt.kicad_pcb and its schematic PCB/Tilt.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Tilt design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
