TX2M/RX2M
UHF Narrow Band FM multi channel radio modules
UK Version: TX2M-458-5/RX2M-458-5 (100mW)
European version: TX2M-433-5/RX2M-433-5 (10mW)
The TX2M transmitter and RX2M receiver
modules offer a low power, reliable data link
in an industry-standard pin out and
footprint. This makes the TX2M/RX2M pair
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.
Features
