1. Overview
The SLR-434M smart RF modem is a compact, easy to use, wireless modular RF modem for
embedding in other equipment.
In addition to conventional FSK mode communication, it also comes with a LoRa mode for ultra
long distance communication and low bit rate. With its superior receive sensitivity using LoRa
modulation, it achieves both specific low power output, with a line of sight communication range
of more than 10 kilometers.
Connection to an external microcomputer or a PC via a UART and our proprietary command
system fostered in the industry make it possible for you to easily transmit/receive data.
Also you can control up to 8 contacts.
