Logic Board
The Tesla LDU Openinverter logic board allows you to control a Tesla Large Drive Unit in EV conversions and custom electric vehicles. It will NOT work in a Tesla vehicle.
All components and connectors are fully assembled. No soldering required!
The board has been flashed with the latest firmware and parameters and is fully tested. Once installed, you can access the inverter parameters via an easy-to-use web interface to tune the motor for your application.
Openinverter boards include an onboard ~5kW charging feature, so you don't need to buy and integrate a separate onboard charger if fast charging is not required. However, this advanced feature should only be implemented by trained professionals as it requires working with high voltage.
