Tesla Model 3 Y Drive Unit Open Source Logic Board

Description

For almost 5 years now I've been working on a solution to provide an open source control system for the Tesla Model 3 / Y drive units. A few years ago I started the project to reverse engineer parts of the original Tesla OEM board like the gate driver and blend it with some OpenInverter goodness. Thanks to a good friend collaborating on the project this year it's picked up some speed.

Design is being done using Kicad 8.

Now updated to Kicad 9 and project now fully opensource :
