VHF Narrow Band FM multi channel TX and RX
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.
