The CDP-TX-02F and CDP-RX-02F are compact, frequency-selectable radio data modules operating in the 434 MHz ISM band. They are equipped with a frequency synthesizer system and a microcontroller, allowing selection of 128 RF channels via a 7-bit DIP switch. Their small size and low voltage operation make them suitable for environments with multiple radio transmitters.
