The BUS2S-485 is a RS485 Frontend expansion board. It is design to fit onto the Frontend connector of our MicroX range of boards. When connected to the frontend port of a compatible MicroX SBC board it will add a RS485 interface to it. For a list of compatible SBC boards see documentation on old site (link above).
It is supplied with a 5 pin 3.81mm screw type terminal block plug and SP485EC driver chip as show in the picture. The RS485 bus signals, ground and optionally (selected via straps) the positive supply are made available on a 5 pin 3.81mm terminal block connector. See the datasheet for details.
A 3mm red LED is connected to the Frontend connector signal B6. When plugged into a SBC board, this signal is routed to PIC port pin RB6. The user application running on the MicroX SBC board can control this LED via port pin RB6.

This board can also be used as a CAN BUS expansion board. For this to work, the RS485 driver IC must be removed (IC1), and a CAN BUS driver must be inserted into socket IC2. The MCP2551 CAN BUS driver chip can be used. A PIC chip with a onboard CAN driver must of course be used – like the PIC18F458.
