Thingy:91 is a cellular and GNSS IoT prototyping platform with world-wide coverage across 700MHz to 2200MHz, created by Nordic Semiconductor and Fractus Antennas. Based on Nordic’s nRF9160 SiP multimode LTE-M/NB-IoT system-in-package with GPS, the battery-powered Thingy:91 comes with a roaming SIM card, 16 sensors and a nRF52840 for short-range wireless communication with Bluetooth 5, Thread, Zigbee and ANT. The SIM is a Nano ...

The Renesas RX65N Cloud Kit is aimed at those prototyping sensor-based IoT end-points with secure links to the cloud

Rockley Electronics is a silicon photonics start-up that recently raised $52m in a funding round, bringing its total to $165m. With all this investor interest, it was time to find out exactly what the company is offering, so Electronics Weekly spoke to its founder and CEO Andrew Rickman – and industry veteran with some history in photonics. In 1988, Rickman founded pioneering ...

UK consultancy 42 Technology has ported a Rust programming language application to a single-chip IoT device, claiming it as a world first. “Rust is a very-high-performance alternative to systems programming languages such C and C++, which avoids the memory safety issues that plague those languages, and without the complexity and overhead of Java,” according to the firm. “It is the ...

Würth is offering a surface-mount single port for 1000Base-T Ethernet industrial LAN connections. Each device contains four sets of inductive components, one for each twisted pair within the Ethernet cable. “WE-LAN AQ transformer convinces in an exemplary fashion in terms of crosstalk, insertion loss, return loss, differential and common-mode rejection,” claimed the firm. This data sheet gives the numbers as: crosstalk ...

Long-term health monitoring of adults, babies and small children without concern for skin injury or allergic reactions is the aim of a project at Georgia Tech, which has produced a stretchy patch that can broadcast electrocardiogram (ECG), heart rate, respiratory rate and motion activity data. Connections are to gold skin-like electrodes through printed conductors that can stretch with the medical ...

Radio modules using STMicroelectronics’ STM32WB55 wireless microcontroller are available from Arrow Electronics. The Sharky modules were co-developed with Italian designer, Midatronics. The microcontroller integrates a 2.4GHz RF transceiver supporting Bluetooth 5 (including Bluetooth Low Energy), Thread, and ZigBee stacks. Its dual Arm Cortex-M core architecture enables real-time secure application performance running on the 64MHz Cortex-M4F core, and concurrently managesthe radio ...

Believed to be one of the first devices to support Bluetooth Core 5.1, Nordic Semiconductor’s nRF52811 SoC is now available from Rutronik UK The Bluetooth Core 5.1 specification was introduced early this year and adds tracking and location functions. The nRF52811 is a multi-protocol SoC that supports IEEE 802.15.4 for Thread and ZigBee and also Bluetooth Direction Finding and Bluetooth Long Range for direction ...

LoRaWAN technology is low power, inexpensive, reliable and is ready for adoption in smart healthcare, writes Richard Lansdowne.   The medical and healthcare sector is ripe for development using LoRa devices and wireless radio frequency technology. Critical smart healthcare applications, in particular, can benefit from LoRa, a long range digital wireless data communication technology patented by Cycleo, which was acquired ...
