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 […]

$6.5 RAK11160 LoRaWAN, WiFi, and BLE module pairs ESP32-C2 with STM32WLE5 for low-power, long-range IoT

RAK11160 ESP32-C2 STM32WL LoRaWAN module

RAKwireless RAK11160 is a new low-cost, low-power LoRaWAN, WiFi 4, and Bluetooth LE module based on ESP32-C2 (ESP8684) wireless microcontroller and STM32WLE5 LoRa SoC for LPWAN IoT applications. The company noticed that many people would combine their STMicro STM32WL-based RAK3172 WisDuo LoRaWAN module with an ESP32 module to add WiFi and/or Bluetooth connectivity to their projects besides LoRaWAN. So RAKwireless decided to offer a module combining both STM32WL and ESP32-C2 to offer a cheap and much more compact solution to their customers. RAK1160 was born.
