A DIY smart eBike display and controller.
Why?
I made this because I really like eBikes; they are just fun. I have always wanted my own, but off the shelf they are way too expensive. So I thought of going the custom route, making my own controller. But then I thought, if I am really going to do this, I am not going to get some normal boring eBike I want my eBike. And that is how this came to be.

Questions
How big is the Controller PCB?
It measures 74.1 × 99.3 mm and has 4 copper layers, 1.59 mm thick.
What parts does the Controller use?
78 parts, built around the SN65HVD230DR, DRV8353SRTAT, TD1501HS50 and AMS1117-3.3. 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 Controller KiCad files?
From the Choccy-vr/BeanBike repository on GitHub, at the commit this page was made from: the board is PCB/BeanBike/Controller/Controller.kicad_pcb and its schematic PCB/BeanBike/Controller/Controller.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Controller design in my own project?
Its repository states no licence, so its author keeps all rights: ask Choccy-vr before reusing the design.
