TR2M/TR2I
Multi-
Narrow Band FM Multi-channel UHF Transceiver
The TR2M transceiver module offers a low power,
reliable data link in an industry-standard pin
out and footprint. This makes the TR2M ideally
suited to those low power applications where
existing wideband modules have insufficient
range, or where multi-channel operation is
needed. Two versions are available, covering the
458.5-459.1MHz UK band (at 100mW) and the
European 433.05-434.79MHz band (at 10mW).
Features
