VHF Narrow Band FM Multi channel radio modules: TX2M/RX2M

The RX2M receiver and TX2M transmitter 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.
