RX1L  
Low current Narrow Band VHF receiver  
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.  
Figure 1: RX1L-173.225-5 receiver

NOTES:  
1. ‘+3V out/in’ can be used to power the RX1L receiver from an external regulated 3V supply.  
2. While pin equivalent to the RX2M450, the RX1L lacks carrier detect, RSSI, modem or multi channel  
functions.
