Repository Architecture
This repository is divided by 4 main folders:
- Docs: You'll find here our consult documents, and documentation of the project.
- Firmware: You'll find here everything you need to build the firmware and in case of needed, modify it.
- Hardware: You'll find here the KiCad projects with theirs libraries so the design is fully portable.
- Mechanical: You''ll find here all the FreeCad files to print/modify/understand the mechanics of the device.
You will find more information on each README in each folder, in order to keep this readme short.
Previous Versions
It's important to note that this repository is under development, if your interested on one "The Byte" device already working, you should jump to the Realese section of this repository to get the V1.0
Version 1.0
The version 1.0 has this architecture based on Seeeduino XIAO and all the connection is done by USB.

Questions
How big is the BYTE Capacitive PCB?
It measures 18 × 23 mm and has 4 copper layers, 0.8 mm thick.
What parts does the BYTE Capacitive use?
14 parts, built around the AD7147PACPZ-1500R7. 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 BYTE Capacitive KiCad files?
From the oneohm/BYTE repository on GitHub, at the commit this page was made from: the board is Hardware/BYTE_Sensor_Pack/BYTE_Capacitive/BYTE_Capacitive.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BYTE Capacitive design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
