Spartan 3 Lite OEM is a low-cost, miniature Wideband O2 Controller suitable for integration into your own products/projects. Spartan 3 Lite OEM is a complete Wideband O2 Controller requiring only an external inline fuse on 12V supply. Spartan 3 Lite OEM is based on our Spartan 3 Lite OEM Wideband Controller.

For evaluation, we recommend Assembled LSU 4.9 Connector which solders directly to Spartan 3 Lite OEM modules.

Spartan 3 Lite OEM does not have CAN Bus.
