DIN-rail mountable LoRaWAN control terminal offers RS485, analog input, and digital I/Os

The DFRobot LoRaWAN Control Terminal is a compact, DIN-rail mountable industrial IIoT terminal that features long-range LoRaWAN connectivity with local sensing and control capabilities. It’s designed for industrial, agricultural, and building-automation scenarios that need reliable, low-power wireless communication up to 4 km. The terminal supports the standard LoRaWAN protocol (OTAA/ABP, Class A/C) with up to 4 km line-of-sight range and works with private gateways or public networks like TTN. It integrates a 0–10V analog input, optically isolated digital inputs, and RS485/Modbus sensor support, along with a built-in relay output for direct actuation. There’s also support for visual rule-based automation for relay switching, RS-485 commands, or uplink messages; the device continues operating offline using preset logic. The unit operates from 12–24V, includes adjustable transmission parameters, and supports firmware upgrades and factory resets.

Giveaway Week 2025 – RAKwireless Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit

It turns out we don’t have two, but three companies offering free samples on CNX Software this year. The last one is a regular, and RAKwireless joins us for the fifth year running with a Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit that can be useful for industrial automation and asset-tracking applications. Regular readers may recall that it is the same prize as last year. While I usually prefer getting a new devkit, the company didn’t launch any this year (just some Meshtastic kits). The good news is that if you missed out last time around, you have a chance to give it another go. Here’s what the winner will get as a reminder: RAK4631 WisBlock Core Module based on Nordic Semi nRF52840 Arm Cortex-M4F microcontroller @ 64 MHz with 1 MB Flash, 256 KB RAM, Bluetooth Low Energy 5.0 protocol stack Semtech SX1262 LoRa Transceiver with LoRaWAN 1.0.2 protocol stack […]

RAK3112 WisDuo LoRa + WiFi + BLE module targets Edge AI and Meshtastic UI

RAKwireless “RAK3112 WisDuo Module for Edge AI with LoRa” combines an ESP32-S3 WiFi and BLE SoC with a Semtech SX1262 LoRa transceiver for Edge AI applications and Meshtastic user interfaces. The 3-in-1 LoRa + WiFi + BLE module is an update to the ESP32-based RAK11200 WisDuo LoRa module, which has limitations in terms of computing power and memory. Those became apparent in more demanding applications such as Edge AI or complex mesh networks. With 16MB of flash and 8MB of PSRAM and a more powerful ESP32-S3 microcontroller, the RAK3112 WisDuo module overcomes those limitations for camera and audio processing, as well as mesh networks like Meshtastic. It also offers a more powerful alternative to the pin-compatible RAK11160 STM32 + ESP32-C2 module that’s better suited for battery-powered sensors. RAKwireless RAK3112 specifications: Main MCU – Espressif Systems ESP32-S3 CPU – Xtensa 32-bit LX7 dual-core CPU @ 240 MHz with vector instructions, AI […]

Core1121 sub-GHz, S-Band, and 2.4GHz LoRa module features through holes and castellated edges

The Waveshare Core1121 is a compact, multi-band LoRa module based on the Semtech LR1121 transceiver with support for Sub-GHz (150–960MHz), S-band (1.9–2.1GHz), and 2.4GHz ISM bands, and exposing GPIOs through both through and castellated holes. Key features include support for LoRa, (G)FSK, and LR-FHSS modulation schemes, AES-128 encryption, and compatibility with the SX126X/SX127X series for easy migration. We just noted Seeed Studio’s Wio-LR1121 last week with a very similar, yet more compact design with only castellated holes, and before that, the LR1121 was used in the MuRata Type-2GT module and a LILYGO module as an option for the T-Eth Elite board. Core1121 specifications: RF Transceiver – Semtech LR1121 Frequency bands Sub-GHz (150MHz ~ 960MHz), Different varieties for Europe, North America, Oceania, Asia S-band (1.9GHz ~ 2.1GHz) 2.4GHz ISM frequency bands Output Power Up to 22dBm @ 868/915 MHz (Sub-GHz) Up to 13dBm max @ 2.4GHz Receiver Sensitivity -127dBm @ Sub-GHz, SF7, CR4/5, […]

RAKwireless Raspberry Pi CM4-based industrial gateway supports both MIOTY and LoRaWAN

WisGate Connect for MIOTY LoRaWAN gateway

The WisGate Connect for MIOTY is an industrial-grade hybrid IoT gateway with support for both MIOTY and LoRaWAN protocols. Built around the RAK7391 carrier board for Raspberry Pi CM4, it is designed for long-range IoT applications, including intelligent street lighting, waste management, environmental monitoring, and traffic flow control. In addition to dual-protocol (MIOTY and LoRaWAN) support, it features USB 2.0, USB 3.0, and a USB-C port for flashing, an HDMI output, and a UART header for debugging. Backhaul options include Wi-Fi, Ethernet, or an optional 4G LTE module. The gateway can be powered in two ways: a wide input voltage DC jack or terminal block, or optional PoE+. We first wrote about the MIOTY Standard back in April 2020. After that, in September 2021, we saw Silicon Labs introduce EFR32FG23 (FG23) and EFR32ZG23 (ZG23) SoCs with MIOTY support, but it’s been a while since we’ve covered products built around this standard.

Dual-channel LoRaWAN AC energy meter features 10A/100A CT clamps, measures temperature and humidity

AgroSense 2 Channel LoRaWAN AC Current Monitor

The AgroSense AGLW2CT is a dual-channel LoRaWAN-based industrial AC energy meter that utilizes 10A and 100A CT clamps to measure power consumption non-invasively. The device features two 0–5V analog inputs for the clamps, an AHT20 temperature & humidity sensor, and local storage for 3,300+ records. It supports LoRaWAN 1.0.3 OTAA Class C and works with TTN, Datacake, and CloudStudio. The device operates within the -40°C to 85°C industrial temperature range and is suitable for contactless current sensing, overload/no-load detection, and machine health monitoring. We had previously covered, and even reviewed, several Wi-Fi-connected CT clamps meters such as the MachineQ’s MQpower CT, Seeed Studio’s XIAO-2CH-EM, and Emporia’s Vue Gen 2 energy monitor, but it’s the first time we’ve come across a LoRa AC energy meter with CT clamps. Earlier this month, we noticed the MOKO LW005-MP LoRaWAN Smart Plug and power meter, but it relies on direct AC power measurements and […]
