RX1L
|
| |
|
The RX1L receiver modules
have very low current consumption (1mA) and it offers a
reliable data link in an industry-standard pin out and footprint.
This makes the RX1L ideally suited to those low power applications
where existing narrow band modules are not suitable for
prolonged battery powered application. Two versions on the
151.300MHz and 173.225MHz frequencies are available. RX1L
is compatible with the Radiometrix TX1 and BiM1T transmitters.

regulated 3V supply.
2. While pin equivalent to the RX2M450,
the RX1L lacks carrier detect, RSSI, modem or multi channel functions.
