RDL2
UHF Multi Channel Wide Band FM Transceiver
RDL2 is a half-duplex multi channel
wideband FM transceiver in a BiM series
footprint and operates on 433.05-434.79MHz
European SRD band.
This makes the RDL2 ideally suited to those
low power applications where low cost
multi-channel operation is required.

The RDL2 is a half duplex radio transceiver module for use in high-speed bi-directional data transfer
applications at ranges up to 300metres. The small footprint of 23 x 33mm together with low power
requirements of <28mA @ 5V enable convenient PCB installation.
RDL2 allows operation on one of 5 pre-set frequencies in the 433MHz European licence exempt
frequency band. These frequencies are non-overlapping and simultaneous operation of RDL2s in the
same area on different channels will be possible. Units are supplied on 433.92MHz (Ch0) as default.
