README
README.mdPCB Design in Git
- We will be using git to store KiCad files as well so that we can have a running record of them.
- Put all the PCBs in a subfolder in the PCB repo.
- Make a branch for your board, and only work on that board on the corresponding branch.
- Don’t delete your branch once you merge it; keep making changes on that branch.
- Only one person should work on a board at a time, and all changes should be committed before the next person works on it.

Questions
How big is the SensorMicrocontroller PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SensorMicrocontroller use?
39 parts, built around the SC0915, ADS1115IDGSR, TLP2355(TPL,E and RR1220P-103-D. 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 SensorMicrocontroller KiCad files?
From the WheelchairSeniorDesign/PCBs repository on GitHub, at the commit this page was made from: the board is SensorMicrocontroller/SensorMicrocontroller.kicad_pcb and its schematic Joystick/JoystickPCB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SensorMicrocontroller design in my own project?
Its repository states no licence, so its author keeps all rights: ask WheelchairSeniorDesign before reusing the design.
