Addon board for microrusEFI ECU. Wideband controller wiring is based on https://github.com/mck1117/wideband, official rusEFI wideband controller. This is a version using STM32F072C8Tx or STM32F072CBTx MCU in LQFP48 package. (STM32F042C6T6 is not recommended for future release)
This addon board has build-in rusEFI wideband controller, microSD card slot and K-Thermocouple controller. It can be used on all MREs with appropriate connector headers.
Wideband controller requires:
- CAN bus connectivity
- additional power supply from 12V_MREL pin for sensor heater. (not required for "my" MRE versions - R0.5.5rc, R0.6.1rc)
LSU 4.9 sensor wires are connected via MOLEX MicroFit 3x2 connector 43045-0601 or 43045-0612
K-Thermocouple wires are connected via MOLEX MicroFit 2x1 connector 43045-0202 or 43045-0212
Latest version use 2x4 pin connector MOLEX 43045-0800 or 43045-0812 (6pins for LSU and 2pins for K-Thermocouple).
Two analog outputs for external gauages are in progress.
