DFRobot has released a compact LoRaWAN control terminal designed for industrial automation, agriculture, and building management applications. The DFRobot LoRaWAN Control Terminal packs long-range wireless connectivity with local sensing and control capabilities into a DIN-rail mountable package measuring just 8.9 x 5.3 x 2.4 cm (3.5 x 2.1 x 0.9 inches).
The terminal supports the standard LoRaWAN protocol with both OTAA and ABP activation modes, offering line-of-sight range up to 4 km (2.5 miles). It works with private gateways or public networks like The Things Network. For I/O, the unit includes a 0-10V analog input with 15-bit resolution, two optically isolated digital inputs supporting 5-24V, RS-485 with Modbus RTU support, and a relay output rated for 24VDC or 220VAC at 3A. The device operates on 12-24VDC and functions across a temperature range of -10 to 60°C (14 to 140°F).
Configuration happens through DFRobot's LoRaWAN Tool software, which provides access to network parameters, acquisition settings, and a visual rule engine. The firmware supports up to eight automation rules with multiple actions, allowing the terminal to handle data acquisition and control tasks autonomously without external programming. This means the device continues operating offline using preset logic for relay switching, RS-485 commands, or uplink messages. Full documentation is available on the DFRobot wiki.
The LoRaWAN Control Terminal is available in two regional variants: EU 868 MHz with 16 dBm transmit power and US 915 MHz with 22 dBm transmit power. Both versions are priced at $35 (€32) and ship with the main unit, rubber antenna, mounting hardware, DIN-rail clips, and terminal block connectors.
