Multi Channel Radio Transmitter and Receiver (128 Channels)CDP-TX-02F, CDP-RX-02F
For the CDP-TX-02F, CDP-RX-02F, frequency setting is performed with the 7-bit switches.
They are suitable for various application fields such as wireless data communication, remote control, telemetry or wireless security systems. They are easy to use and integrate into application systems.
CDP-TX-02F and CDP-RX-02F are equipped with a frequency synthesizer system with micro controller. Available frequency ranges are from 128 preprogrammed channels. The compact size, low operating voltage and frequency selectability of the CDP-02F make it ideal for various applications where its interference rejection and propagation distance range is far better than similar RF modules based on wide band SAW-resonator frequency generators.
The CDP-RX-02F receiver has excellent blocking and adjacent channel selectivity.

Evaluation Tools: ECB-03, DCB-03
The test board ECB-03 (Encoder board) and DCB-03 (Decoder board) will save you time and effort for evaluating CDP-TX-02F, CDP-RX-02F modules. Communication range can be tested easily by checking the LEDs on the decoder board.
ECB-03 and DCB-03 do not include modules CDP-TX-02F, CDP-RX-02F. Please make sure to order them if needed.
