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
