== General description ==
[[File:SLH2-comm-main.png|800px|center]]
<br> 
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
