CDP-TX-05M-R and CDP-RX-05M-R are low power narrow band FSK transmitter and receiver modules, designed for industrial applications operating in sub 1-GHz. The modules contain most of the components necessary for radio transmission in compact cases. The RF channel is fixed but selectable within 4 preprogrammed 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.

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

The test board will save you time and effort for evaluating CDP-TX-05M-R and CDP-RX-05M-R 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-05M-R and CDP-RX-05M-R. Please make sure to order them if needed.
The boards are common for CDP-TX-04S-R / RX-03AS/BS-R models.
Features
- 4-push buttons and output LEDs.
- Encoder and decoder IC MSM6305 with the user selectable 1024 address codes.
