The Dragino RS485-BL is a RS485 / UART to LoRaWAN Converter for Internet of Things solutions.User can connect RS485 or UART sensor to RS485-BL converter, and configure RS485-BL to
periodically read sensor data and upload via LoRaWAN network to IoT server.

RS485-BL can interface to RS485 sensor , 3.3v/5v UART sensor or interrupt sensor. RS485-BL provides a 3.3v output and a 5v output to power external sensors. Both output voltage are controllable
to minimize the total system power consumption.

RS485-BL is IP67 waterproof and powered by 8500mAh Li-SOCI2 battery, It is designed for long term use for several years.

RS485-BL runs standard LoRaWAN 1.0.3 in Class A. It can reach long transfer range and easy to intergrate with LoRaWAN compatible gateway and IoT server.

Each RS485-BL pre-loads with a set of unique keys for LoRaWAN registration, register these keys to local LoRaWAN server and it will auto connect after power on.

Default FW in AS923, but it support US915, AU915 and all 900MHz Frequency by loading different FW, it could also support 868MHz if loading 868MHz FW, but there will be slight 0.5-1dB loss here.
