The Dragino RS485-NB is a RS485 / UART to NB-IoT Converter for Internet of Things solutions. User can connect the RS485 or UART sensor to the RS485-NB converter, and configure RS485-NB to periodically read sensor data and upload via NB-IoT network to IoT server.
RS485-NB can interface to the RS485 sensor, 3.3v/5v UART sensor, or interrupt sensor. RS485-NB provides a 3.3v output and a 5v output to power external sensors. Both output voltages are controllable to minimize the total system power consumption.
