Spartan 3 OEM

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

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

Spartan 3 OEM Specifications:
