The Dragino RS485-LN is a RS485 to LoRaWAN Converter. It converts the RS485 signal into
LoRaWAN wireless signal which simplify the IoT installation and reduce the installation/
maintaining cost.
RS485-LN allows the user to monitor / control RS485 devices and reach extremely long ranges.
It provides ultra-long range spread spectrum communication and high interference immunity whilst
minimizing current consumption. It targets professional wireless sensor network applications such
as irrigation systems, smart metering, smart cities, smartphone detection, building automation,
and so on
Features:
STM32L072CZT6 MCU
RS485-LN-AU915
Flexible rules to connect different RS485 devices
RS485-LN-EU433
RS485-LN-KR920
RS485-LN-CN470
RS485-LN-AS923
For data uplink, RS485-LN sends user-defined commands to RS485 devices and get the return
from the RS485 devices. RS485-LN will process these returns according to the user-define rule to
get the final payload to upload to LoRaWAN server.
