Particle’s M-series multi-radio devices connect anywhere with WiFi, cellular, NTN satellite, and LoRaWAN connectivity

Particle Industries Inc., an IoT Platform-as-a-Service company, has announced a new line of multi-radio boards and modules that offer multiple connectivity options in a single product. Particle is a complete edge-to-cloud IoT development platform that offers hardware products and software tools for creating IoT solutions. The company’s latest product, the M-series, has a bold tagline: connect anywhere. Although wireless connectivity has come a long way, there is no single wireless technology that works everywhere. Particle’s M-series aims to address that problem by bundling multiple radios – Wi-Fi, cellular, satellite, and LoRaWAN – into one product. Particle is looking to expand from its two primary wireless technologies: Wi-Fi and cellular, and add two more radios, satellite and LoRaWAN, for broader coverage. These two radios will cover devices in areas such as enclosed spaces (boiler rooms, elevator shafts, basements, and mines) and remote locations (methane sensors in oil and gas plants, boats, […]

Waveshare ESP32-S3 4G dev boards feature LTE Cat-1, 2G, and camera support

Waveshare has recently launched two new ESP32-S3 4G dev boards – the ESP32-S3-SIM7670G-4G and the ESP32-S3-A7670E-4G. These boards support 4G LTE Cat-1, Wi-Fi, Bluetooth, and GNSS, and come with an OV2640 camera, and a battery holder for a 18650 battery. The main difference between the two is that the A7670E module also supports 2G GSM/GPRS/EDGE at 900/1800MHz while the SIM7670G module does not. The board has two rows of I/Os including GPIO, I2C, SPI, ADC, and USB 2.0. It also has a USB-C port for power and programming, a slot for a MicroSD card, and an option to connect an external speaker. There’s a USB switching IC and DIP switch for easily connecting the module to a PC for internet or debugging. Waveshare ESP32-S3 4G Dev Boards Specification: Communication module A7670E 4G – A7670E Cat-1 4G module supporting 4G Cat-1 + 2G networking, GNSS positioning, telephone calls, and SMS. SIM7670G […]

Pico 2G Expansion adds GSM/GPRS & GNSS to Raspberry Pi Pico (Crowdfunding)

You may have heard about the 2G/3G sunset with the older cellular networks being phased out in many countries. But it’s not always straightforward, as telecom operators may have to obtain regulators’ permission for the shutdown notably because of the eCall emergency services integrated into cars in Europe. Eventually, eCall will be migrated toward IMS Voice and 2G M2M services to 4G LTE IoT and 5G LPWA, but in the meantime, 2G networks are still operating in parts of the world, and UK-based SB Components has just introduced the Pico 2G Expansion board for Raspberry Pi Pico based on the SIM868 module. Raspberry Pi Pico 2G Expansion specifications: Compatible with Raspberry Pi Pico board Display – 1.14-inch LCD Cellular & GNSS Connectivity SIM868 module with GPRS multi-slot class 12/10, mobile station class B GSM 850/900/1800/1900 MHz GNSS – GPS/GLONASS/BDS Bluetooth 3.0 with audio support SIM card holder 2x SMA antenna […]
