TX1M/RX1M
VHF Narrow Band FM multi channel radio Transmitter & Receiver
Band
UK Version: RX1M-173-5/TX1M-173-5 (10mW)
The TX1M transmitter and RX1M receiver
modules offer a low power, reliable data link in
an industry-standard pin out and footprint.
This makes the TX1M/RX1M pair ideally suited
to those low power applications where existing
wideband modules have insufficient range, or
where multi-channel operation is needed in
VHF frequency.
