README
readme.mdEbike
This repo contains the software and CAD files for my ebike.
Software
All the software is currently written in Arduino and uses a few different libraries.
Hardware
All the CAD files are made in Fusion 360/KiCAD and are put here in iges format/as a KiCAD project. At the moment my ebike runs a 48 volt 1500w brushless motor running at a maximum of 30 amps. My motor is powered by a FSESC motor controller, which I interface with over UART with a custom ESP32 board. My battery is a 48 volt 13AH li-ion Unit Pack Power battery pack.

Questions
How big is the Ebike Board PCB?
It measures 49.5 × 87.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ebike Board use?
30 parts, built around the ESP32-WROOM-32 and SR306. 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 Ebike Board KiCad files?
From the klay2000/EBike repository on GitHub, at the commit this page was made from: the board is EBike CAD/Electrical/Control Board/Ebike Board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ebike Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask klay2000 before reusing the design.
