The module has been designed to enable SPI communications of the lambda modules with 3.3V Arduino boards.

The module is stacked on the lambda module and the connection cables to the arduino board will be connected to it.

• Compatible with lambda modules.
  • 01M11V00. Wideband lambda module.
  • 01M21V00. Wideband lambda module with rpm.
  • 01M30V00. Double wideband lambda module with rpm and 3 analog inputs.
  • Others.
• Compatible with 3.3 V Arduino boards via 3.3-5 V SPI adapter.
  • Arduino Nano. (SPI comunication, with SPI adapter.)
  • Others, compatible but not tested.
