433MHz Long Range Radio 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. And the best part - with 10mW output, it reaches over 500m!
This unit can be attached to TTL level serial (for microcontrollers) or directly to RS232 for incredibly simple serial cable replacement!
Supported Antennae: Kit comes with 1/4 wave 50Ohm antenna and communications cable!
Sold in single units.
