Includes:
Openinverter LDU Logic Board
Openinverter SDU Logic Board
Two New SDU Current Sensors
Fully Labeled SDU Wiring Harness/Pigtail
SDU Pinout Card
All components and connectors are included. Connectors must be soldered. The board has been flashed with the latest firmware and parameters. 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 onboard ~5kW charging, so you don't have to buy and integrate a separate onboard charger if fast charging is not required!
NOTE: Installation is not for beginners! - Requires fundamental electronics knowledge and soldering surface mount connectors.
Watch this video for more information.
All components and connectors (aside from the current sensors) have been fully assembled and tested with the latest firmware and default parameters. Once installed, you can access the inverter parameters via an easy-to-use web interface to tune the motor for your application. SDU boards supplied by Westside EV have been slightly modified so that the plastic MX150 connector fits the board better to avoid breaking off the little leg protruding from the bottom of the connector.
Openinverter boards also feature onboard ~5kW charging, so you don't need to buy and integrate a separate onboard charger if fast charging is not required!
NOTE: Installation is not for beginners! - Requires soldering delicate current sensors and moving fragile plastic parts from the old board to the new board.

Two new Melexis 7.3mV/mT current sensors are included. You should first try to reuse the existing sensors, but they can be challenging to unsolder without damaging them. Watch the install video linked above to see how to unsolder them from the OEM logic board.
If the existing sensors get damaged, they must be removed from the potting compound in the sensor rings. To do so, heat them with a hot air gun, soldering iron, etc. Once hot enough, they should come out of the potting compound, leaving behind a small hole. Place the new sensors into the holes left behind, ensuring they are correctly oriented. The 45-degree angled side should point towards the phase wires and away from the board. Then, carefully install the logic board on top of them while threading the four leads through the corresponding holes in the PCB. Solder them in place once the board has been secured with a few screws. Be sure to trim down the protruding leads to avoid them bending and shorting out.
A fully labeled MX150 wiring harness pigtail is included with this bundle. Made with three feet of high-quality 18 AWG silicone wire, color-coded and labeled specifically for the Openinverter logic board pinout. A full-color pinout card is included as well. Custom lengths can be ordered for $5 per additional foot. Please contact the seller for custom lengths.
