Compact Multi Channel Transmitter and Receiver (4 Channels)CDP-TX-07M/MP, CDP-RX-07M/MP

CDP-TX-07M/MP and CDP-RX-07M/MP are low power narrow band FSK transmitter and receiver modules, designed for industrial applications operating in 434 MHz. The modules contain most of the components necessary for radio communication in compact cases. The operating RF channel can be selected from 4 preset frequency channels. The receiver is double-superheterodyne and equipped with a SAW filter, ensuring high sensitivity and very good selectivity for stable and long range communication.

The CDP-TX-07M, CDP-RX-07M is compatible with CDP-TX-05M-R and CDP-RX-05M-R

CDP-TX-07MP, CDP-RX-07MP has connection pins S1 and S2 allowing frequency setting to be performed externally.

Evaluation Tools: TB-CDP-TX-04S, TB-CDP-RX-03AS

The test board will save you time and effort for evaluating CDP-TX-07M and CDP-RX-07M modules. Communication range can be tested easily by checking the LEDs on the decoder board TB-CDP-RX-03AS.

TB-CDP-TX-04S and TB-CDP-RX-03AS do not include modules CDP-TX-07M and CDP-RX-07M. Please make sure to order them if needed. The boards are common for CDP-TX-05M-R / RX-05M-R models. Also the testboard cannot be used for CDP-TX-07MP and CDP-RX-07MP.
