The TRM-868-NT is a FM Transceiver modules have been designed for bi-directional wireless data transfer in the 868 MHz Band (for European operation). The transceiver module has exceptional sensitivity, giving it an outstanding range of up to 3,000 feet (914 meters, line of sight).
It has two interfaces - One is UART which supports datarates of up to 56kbps and the other is a transparent interface that bypasses the protocol engine and directly modulates the RF carrier. This interface supports data rates of up to 300 kbps. The Transceiver is available in a compact reflow-compatible surface mount package, and does not require any additional RF components other than an antenna making it easy to integrate in to systems.
