Fujitsu introduces Wirepas Massive USB dongle for location tracking, IoT mesh networking

I was first introduced to Wirepas Massive mesh networking a few days ago when I covered Solidrun Solidsense N8 IoT Compact Wirepas Massive gateway comprised of an NXP i.MX 8M Nano processor running Linux and a module based on Nordic Semi nRF52832 wireless MCU handling Wirepas Massive through its 2.4 GHz radio. It turns out there’s an easy way to add the new mesh networking technology to existing gateways: USB dongles. Fujitsu has launched the FWM8BLZ09x Wirepas Massive USB dongle family, based on the more recent nRF52833 SoC, with Anchor, Tag, and Sink models. Fujitsu FWM8BLZ09x specifications: USB Dongle Types Anchor – FWM8BLZ09P Tag – FWM8BLZ09T Sink – FWM8BLZ09S Wireless MCU – Nordic Semi nRF52833-CJAA Cortex-M4 microcontroller @ 64 MHz with 8 KB RAM, 512 KB Flash, 2.4 GHz radio Connectivity Wirepas Massive mesh networking Transmit power – +8dBm max.

LILYGO T-32C3 – A small ESP32-C3 WiFi & BLE IoT module with 4MB flash

We’re slowly starting to see more hardware-based on ESP32-C3 RISC-V processor, and LILYGO T-32C3 is a compact module based on the WiFi & Bluetooth LE processor that includes 4MB flash and a PCB antenna. I’d expect T-32C3 to be eventually found in the company’s smartwatches and development boards, and it joins other ESP32-C3 modules from AI Thinker. LILYGO T-32C3 module specifications: SoC – Espressif ESP32-C3 RISC-V processor @ 160 MHz with 400 KB SRAM, 384 KB ROM, 8KB RTC SRAM, 2.4 GHz WiFi 4, Bluetooth 5.0 LE & Mesh Storage – 4MB flash On-board PCB antenna I/Os – 22x castellated holes with GPIO, 3x ADC, SPI, UART, I2C, Boot, Reset, 5V, 3.3V, GND Dimensions – 23 x 11 x 3.5 mm (4-layer PCB) Note the USB interface is not listed in the specs, but USB DN and DP signals are located on GPIO18 and GPIO19 so USB should also be […]

$2 MXCHIP EMC3080 WiFi and Bluetooth LE IoT module integrates Cortex-M33 MCU

MXCHIP EMC3080 Cortex-M33 WiFi & Bluetooth-IoT module

While nowadays most people from the maker community are working with ESP8266 or ESP32 modules or boards for IoT projects requiring Bluetooth LE and/or WiFi connectivity, we’ve also covered some low-cost alternatives such as Bouffalo Labs BL602 or Realtek RTL8710. MXCHIP EMC3080 module offers yet an alternative with 2.4 GHz 802.11 b/g/n WiFi and Bluetooth LE 4.2/5.0. Where it differentiates against other solutions is that it features a more secure Cortex-M33 core clocked at 100 MHz, as found in UNISOC V5663 and Ameba RTL8722DM wireless SoCs, but still getting a fairly low price tag of $2.35 on Seeed Studio, which drops to $2.10 per pieces for orders of 10 or more units. MXCHIP EMC3080 module specifications: MCU – MX1300CF Cortex-M33 processor at up to 100 MHz with 256KB SRAM, 2MB XIP flash, 384 or 512 bytes OTP memory Connectivity WiFi 802.11 b/g/n 1T1R WiFi @ 2.4GHz Single Frequency HT20 support […]

Nokia E63 phone converted into LoRa messenger for secure, off-the-grid communication

While LoRa radios are mostly designed to transmit data from sensors and to actuators, there have been attempts to leverage LoRa for messaging in the past with, for instance, the Meshtastic Mesh Networking Project to help hikers exchanged their GPS coordinates or other short messages, the Raspberry Pi Pico powered PICOmputer with QWERTY keyboard, display, and a LoRa module, and Pine64 is also working on developing LoRa hardware for messaging. Trevor Attema decided to repurpose his Nokia E63 Blackberry-like phone with a custom STM32H7 board with a LoRa radio while keeping the enclosure, display, backlighting, keyboard, and speaker which he calls the Off The Grid Messenger, or OTG Messenger for shorts. The custom board also adds Microchip ATECC608 crypto authentication chip for encrypted messages, and the LoRa Messenger would allow a theoretical transmission range of 16 kilometers in line of sight which would allow a small group of people to […]
