Arduino MKR inspired MKR Windy board is equipped with STM32WL LoRa SoC

We recently wrote about MKR SharkyPro BLE, Zigbee, OpenThread development board based on STM32WB55 MCU and following Arduino MKR form factor, but it turns out Midatronics has also launched a similar-looking board with LoRa connectivity. MKR Windy board features the company’s Windy STM32WL module with an uFL connector and following the same Arduino MKR layout. MKR Windy specifications: Wireless Module – Windy module (MDX-STWLU-R01) Wireless MCU – STMicro STM32WLE5JX/STM32WL55JX Arm Cortex-M4 MCU @ 48 MHz with up to 256KB flash, 64KB SRAM Connectivity Semtech SX126x sub-GHz radio with LoRa, (G)FSK, (G)MSK, and BPSK modulation, 150 MHz to 960 MHz frequency range RX Sensitivity: –123 dBm for 2-FSK,  -148 dBm for LoRa Antenna – uFL connector for external antenna Supply Voltage – 1.8 V to 3.6 V Dimensions : 16 x 26 mm Temperature Range – 40°C to + 85 °C USB – 1x Micro USB port for power and programming […]

STMicro STM32WL Wireless MCU Gets Wireless M-Bus Stack for Smart Meters

STMicro STM32WL was introduced as the world’s first LoRa SoC last year as it combined an STM32L4 Arm Cortex-M4 microcontroller with Semtech SX126x LoRa radio. The company has now partnered with Stackforce to develop a wireless M-Bus (wM-Bus) software stack that leverages the integrated sub-GHz radio and multiple modulation schemes supported by STM32WL microcontrollers. Wireless M-Bus (Wireless Meter Bus) is a wireless protocol specifically designed for remote reading of smart meters, generally gas, water, or electricity meters. The wM-Bus stack developed by Stackforce is said to comply with most of EN 13757-3/-7 specifications from lower to upper layers. The stack notably supports Wireless M-BUS modes S, T and C used throughout Europe in the 868MHz band, as well as the mode N for operation at 169MHz that also happens to be Wize frequency. Stackforce Wireless M-Bus stack for STM32WL also meets requirements for several other metering standards, including the Open […]

STMicro STM32WL is the World’s First LoRa SoC

There is no denying that the Internet of Things is going to disrupt a lot of markets and it’s already happening to some extent. The question being asked is: “What IoT connectivity technology will lead this disruption era?”. One major technology in this connectivity race is LoRa. LoRa’s long-range, low-power, small footprint, simplicity, and the amazing community backing it, have allowed it to find its way into various applications while gaining for the top LPWAN IoT connectivity technology. STMicroelectronics, one of the biggest semiconductor manufacturer, also believes in the potential of LoRa with the launch of STM32WL, making it the World’s first die-integrated LoRa System-on-Chip. Traditional LoRa embedded platforms usually involve the need for a separate MCU chip and different LoRa transceiver chips either coupled together in one single package or separately. This undoubtedly adds extra design complexity, size, and even cost. STMicro hopes to address this with their STM32WL SoC. […]

Solar LLM over Meshtastic

Solar-powered LLM over Meshtastic solution may provide live-saving instructions during disasters and emergencies

People are trying to run LLMs on all sorts of low-end hardware with often limited usefulness, and when I saw a solar LLM over Meshtastic demo on X, I first laughed. I did not see the reason for it and LoRa hardware is usually really low-end with Meshtastic open-source firmware typically used for off-grid messaging and GPS location sharing. But after thinking more about it, it could prove useful to receive information through mobile devices during disasters where power and internet connectivity can not be taken for granted. Let’s check Colonel Panic’s solution first. The short post only mentions it’s a solar LLM over Meshtastic using M5Stack hardware. On the left, we must have a power bank charge over USB (through a USB solar panel?) with two USB outputs powering a controller and a board on the right. The main controller with a small display and enclosure is an ESP32-powered […]

Seeed Studio introduces ESP32-C3-based Modbus Vision RS485 and SenseCAP A1102 LoRaWAN outdoor Edge AI cameras

Seeed Studio has recently released the Modbus Vision RS485 and SenseCAP A1102 (LoRaWAN) outdoor Edge AI cameras based on ESP32-C3 SoC through the XIAO-ESP32C3 module for WiFi and the Himax WiseEye2 processor for vision AI. Both are IP66-rated AI vision cameras designed for home and industrial applications. The RS485 camera is designed for industrial systems and features a Modbus interface, making it suitable for factory automation and smart buildings. The SenseCAP A1102 uses LoRaWAN for long-range, low-power monitoring in remote locations. Both offer advanced AI for tasks like object detection and facial recognition. Besides its built-in RS485 interface, the Modbus Vision RS485 also supports LoRaWAN and 4G LTE connectivity via external Data Transfer Units (DTUs). With over 300 pre-trained AI models, the camera can do object detection and classification tasks making it suitable for industrial automation, smart agriculture, environmental monitoring, and other AI-driven applications requiring high performance. The SenseCAP A1102 […]

LoRaWAN no code ESP32-S3 development platform offers Arduino MKR, MikroBus, FeatherWing, and Grove expansion (Crowdfunding)

Sheffield-based IoT company, inx-systems has developed a programmable LoRaWAN IoT module and a development breakout board that integrates with Arduino MKR, Adafruit FeatherWing, Grove, and mikroBUS shields. The module is powered by an ESP32-S3 microcontroller which comes preloaded with inx’s no-code LoRaWAN software development platform, Lucid. The WAN-4-ALL module has built-in Wi-Fi, Bluetooth, and LoRaWAN connectivity via the ESP32-S3 microcontroller and Seeed Studio Wio-E5 module. This makes the module suitable for short-range, medium-range, and long-range IoT applications such as remote monitoring, home automation, industrial control, and smart agriculture. We have covered other LoRaWAN development platforms such as SB Component’s RAKWireless-based products, Particle’s multi-radio devices, and the UnPhone. The WAN-4-ALL module differentiates itself with the preloaded no-code LoRaWAN development environment and multiple connectivity options.
