## FunKey S Hardware
|
|
This repository contains all the hardware design and production files required to build the [FunKey-S retro-gaming console](https://www.funkey-project.com/) electronic PCBA using the [KiCAD ECAD tools](https://kicad.org/).
|
|
|
|
If you don't want to install these tools but still want to get an idea of what it looks like, you can check the [schematics](https://github.com/FunKey-Project/FunKey-S-Hardware/blob/master/PDF/FunKey%20Schematics.pdf) and the [layout](https://github.com/FunKey-Project/FunKey-S-Hardware/blob/master/PDF/FunKey%20PCB.pdf) in PDF format, the interactive [BOM](https://github.com/FunKey-Project/FunKey-S-Hardware/tree/master/BOM) is directly in HTML format, yo ucan download it and display it in a browser.
