SLH2-comm - multiprotocol communication interface for StarSBC-6ULL Datasheet and Pinout
General description
The SLH2-comm module (“hat”) is dedicated solution for StarSBC-6ULL Single Board Computer. The SLH2-comm module comprises:
- 2xRS232 physical interfaces (with hardware dataflow control – CTS/RTS lines),
- 2xRS485 half-duplex physical interfaces,
- 2xCAN-FD physical interfaces.
The SLH2-comm module can be conveniently mounted using 2,54 mm connectors on the StarSBC-6LL board (as on picture below).
Features
- dedicated communication interface for StarSBC-6ULL
- 2 x CAN-FD
- 2 x half-duplex RS485
- 2 x RS232
- Molex 53048-0510 and dual-row 2,54 mm connectors
