STM32F105 based dual CAN bus gateway / isolator.
Designed for a EMUS BMS CAN to NMEA2000 converter.
But hardware can be used for many CAN gateway or CAN isolation applications.
- STM32F105RCT6 72MHz MCU with 2 internal CAN controllers
- CAN1 BMS (micro-fit 6-pin connector) optionally isolated
- CAN2 NMEA2000 (M12 5-pin connector) optionally isolated
or second micro-fit 6-pin connector
- 4-32V supply voltage
- RGB status LED
- USB-C for firmware updates
- Solder jumpers to use M12 male or female connectors.
- Solder jumpers for the CAN termination resistor.
- Solder jumpers for power output on CAN2 connector.
- EMUS BMS micro-fit 6p. connector (CAN1 & power input)
- NMEA2000 M12 5p. connector (isolated CAN2 & optional power output)
- STM32CubeIDE NMEA2000 battery project example
