This is an active, work in progress super capacitor bank and super capacitor controller board design that is intended to be used with the DJI Robomaster's competetion.
User Guide (Currently non-existent, but will be completed eventually) can be found in Documentation PCB Files can be found in the Design Files folder, with all of the projects being done in KiCAD 8.0.
Use this design at your own risk, as nothing is guranteed to work and/or be safe. Enjoy, and ask any questions in our Team's Discord. :)

Questions
How big is the Control Board V1 PCB?
It measures 75 × 125 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Control Board V1 use?
84 parts, built around the SC0917, TCA39306DCURQ1, XT30UPB-M and XT30PW-F. 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 Control Board V1 KiCad files?
From the Thornbots/Supa-Cap repository on GitHub, at the commit this page was made from: the board is Design Files/Controller Board V1/Control Board V1.kicad_pcb and its schematic Design Files/Cap Bank 2 but the files arent fucked/Cap Bank Rev 2/Cap Bank Rev 2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Control Board V1 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).
