TTL-RS485 Module | Model: M100S48

The TTL-to-RS485 module convert the TTL level to RS485 level. From a 2×5-pin TTL input header to a two-pole screw terminal output port. The pinout of the input pins makes it plug-in compatible with the SBC-SAM9G45 development board's COM0-COM3 expansion headers. A ribbon cable is provided to make that connection. However, the standard 2.54mm pin pitch makes it easy to wire up to practically any development system with TTL UART headers
