Open Source logic board for the Tesla Model 3 rear drive unit. Based on the inverter designed by Johannes Heubner using FOC control.
the model 3 drive unit inverters feature a PCB with both HV and LV circuits, the gate drivers, and logic. thus a simple replacement brain board is not possible. canbus control is complicated and requires use of tesla's diagnostics software for inverter pairing. this is a legal greyzone and not a fully opensource option. Instead a full fledged replacement board with gate drivers was designed to allow full lobotomization of elon, thus gaining full opensource control of the model 3/y drive units!

-3x T10 securing the current sensor trim to the pcb
OR
- 2x T10 screws holding the pryofuse and current sensor trim
Installation Process
See the Tesla Model 3 Drive Unit PCB Install page for a detailed guide on how to install and commission the PCB.
Firmware Parameters
The [stm32-sine M3_DU] firmware has a number of additional parameters and spot values over the standard firmware. The Tesla Model 3 Drive Unit PCB Parameters page describes these.
