Tesla Model 3 Drive Unit PCB

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!

parts needed to be fitted:

-current sensors: MLX91209LVA-CAA-002-SP (can be sourced from original board)

-gate drivers: STGAP1BSTR (can be sourced from original board)

-power transformer: VGT22EPC-200S6A12 (can be sourced from original board)

-(for wiring harness) 30 pin matting connector: Sumitomo Original 6189-6987 61896987 https://www.aliexpress.com/item/1005005920568514.html

-30 pin connector and pins are a private stocked part, so must be salvaged from the original board

-10x torx T20 screws holding the board onto the case

-3x T10 securing the current sensor trim to the pcb
