Upgraded LoRaWAN gateway adds Node-RED support

Jun 24, 2021 — by Jeff Child 1,230 views

ICP Germany has upgraded its “UG65” LoRaWAN gateway to add Node-RED support. The unit supports 8x simultaneous LoRa channels and more than 2,000 LoRaWAN nodes, along with Ethernet, WiFi and optional cellular connectivity.

We missed covering ICP Germany’s UG65 LoRaWAN gateway when it was first announced in mid-March. Now the company has upgraded the UG65 with new features. With the firmware update to version, the UG65 LoRaWAN gateway adds support for Node-RED and provides LoRa class updates.


Developed by IBM, Node-RED is a programming interface that can be used to connect hardware, interfaces and services from the IoT. According to ICP, this feature makes the UG65 more attractive to developers of Smart applications. Target applications for the unit include IoT systems, Smart Infrastructure, sensor-to-cloud systems and Smart Agriculture.

While we’ve seen numerous IoT gateway announcements, there are a handful of products we’ve covered in 2021 that specifically provide LoRaWAN support. These include M3M IOT’s GW-01-WI-FI LoRaWAN gateway, a Raspberry Pi CM3+-based gateway from Innovelec called Dingo LoRaWAN BACnet, and Seeed’s WM1302 LoRaWAN Gateway Module with companion Raspberry Pi HAT. None of those products mention Node-RED support. A gateway that does support Node-RED APIs is a Kickstarter-launched Axon board from Qotex that functions as a WiFi and/or LoRa gateway. Although it lacks LoRaWAN support, the recently announced AIC-100 and AIC-110 gateways from Vecow support the Node-RED browser-based flow editor.

LinuxGizmos’ sister website Circuit Cellar has several recent stories that discuss Node-RED, including “Build an Automated Pest Deterrent System,” “Controlled Circuit Breaking,” “MQ Telemetry Transport (Part 1 and Part 2),” and “IoT Monitoring System for Commercial Fridges.”

The UG65 supports 8x simultaneous channels and more than 2,000 LoRaWAN nodes. Designed for indoor use, the UG65 can process data from sensors at a distance of up to 10 km. LoRa protocol V1.0 and V1.0.2 class A and C are supported. A fully integrated, internal antenna provides LoRa transmission over 8x channels.

At the heart of the UG65 is a 64-bit, 1.5GHz Arm Cortex-A53 processor, but the unit’s datasheet doesn’t indicate which processor is used. For memory, the UG65 has 512MB DDR RAM and 8GB eMMC. Networking includes a 10/100/1000 Ethernet port, 801.11b/g/n, and optional 2G/3G/4G mobile network reception(/access). The UG65 supports multiple back-haul backups with Ethernet, WiFi and cellular and has integrated mainstream LoRa network servers such as TTN and ChirpStack. It also provides built-in network servers and Ursalink Cloud for easy deployment.

The UG65 is enclosed in an IP65-protected housing measuring 180 x 110 x 57mm. Mounting options include desktop-, wall-, or pole-mounting. Although designed for indoor use, the UG65’s temperature range of -40 to 70°C also allows operation in protected outdoor installations, says ICP. The UG65 runs off a voltage of 9V to 24V DC, or alternatively via the PoE (802.3 af) enabled LAN connection. The system supports all common network functionalities, including the protocols MQTT, TCP, and UDP and VPN tunnels like OpenVPN, DMVPN. It also supports access authentication like CHAP, PAP, as well as firewall functionalities and management options.
