- ADM488 RS422 transceiver
- Converts TTL level logic to RS422 levels
- Size: 26 × 45 mm
This TTL-to-RS422 converter features a 2×5-pin TTL input header and a four-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.
