433MHz Long Range Radio Modem from HAC. These small modems use a seamless serial interface - whatever enters the TX pin at 9600bps shows up on the other unit's RX pin. All buffering and error detection is handled internally. With only 10mW output, it had a range of over 500 meters!
This unit can has both TTL level serial (for microcontrollers) and RS232 for incredibly simple serial cable replacement!
