I was out in the countryside with a partially-obedient dog over the weekend. It spontaneously bolts off, the owner told me, for up to a couple of hours. Why not use a dog tracker? I asked naively. It has one, said the owner, but the tracker does not work without mobile phone coverage – when you get home, you know ...

Silicon Labs is aiming at battery-free harvested energy applications with xG22E, a family of wireless microcontrollers covering Bluetooth Low Energy, 802.15.4 or proprietary 2.4 GHz links. “As Silicon Labs’ most energy-efficient SoCs to date, all three will enable IoT device makers to build wireless devices for battery-optimised and battery-free devices that can harvest energy from external sources in their environments ...

Silicon Labs has announced an Arm Cortex-M33 based family of secured wireless microcontrollers covering Matter, OpenThread, Zigbee and Bluetooth LE. Called xG26, it consists of MG26 devices for Matter, OpenThread and Zigbee, BG26 devices for Bluetooth LE and Bluetooth Mesh, and PG26 devices for the same processing power without wireless transceivers. “As users from consumer to industrial sectors extract more ...

Digi International and SparkFun Electronics have designed a development board that adds peripherals around a socket for Digi’s XBee wireless modules. Called ‘SparkFun Digi XBee development board’, it is designed for prototyping cellular IoT applications using one of several Digi’s XBee wireless modules – the socket footprint is Digi’s 13 x 19mm XBee 3 micro form factor – in particular ...

ST has announced a wireless microcontroller with the Bluetooth 5.3 LE software, initially in a 5 x 5mm QFN, and scheduled to be available in a ~2.8 x 3mm chip-scale package. STM32WB09 (right) is built around a single Arm Cortex-M0+ core and will support 2Mbit/s data, long range (coded PHY), advertising extensions, angle-of-arrival, angle-of-departure, LE data packet length extension and ...

U-blox’ LARA-R6 LTE Cat 1 and LARA-L6 LTE Cat 4 cellular modules have been certified to Radio Equipment Directive (RED) cybersecurity, having passed RED article 3.3 d/e/f requirements using ETSI’s EN 303 645 standard. “As cyberattacks and privacy concerns grow, there’s an urgent need for wireless devices and products to feature enhanced security. With stricter regulations on the horizon, manufacturers ...

Nordic Semiconductor is aiming at Bluetooth, Thread and Matter with a secured wireless microcontroller built around a 128MHz Arm Cortex-M33 processor with 1.5Mbyte of non-volatile memory and 256kbyte of ram, which it describes as “ample for concurrent running of multiple protocols” and providing “double the processing power of the nRF52840 SoC while reducing power consumption” – the claim includes halved ...

For the US market, TiePie has created a 915MHz version of the module that allows multiple instances if its PC oscilloscopes to be used together at up to 400m range – a 868MHz version for Europe was introduced in July. Wireless Multi Instrument Synchronization Module WCMI-9 also allows instruments to be used where galvanic isolation is required. The scopes can ...

Nordic Semiconductor has announced EEMBC benchmarks for its forthcoming multi-protocol nRF54H20 wireless microcontroller, which combines multiple Arm Cortex-M33 processors and multiple RISC-V coprocessors “optimised for specific types of workloads”, it said, adding that developers will be able to dynamically change between configurations for processing ability or energy efficiency. Configured for high processing efficiency, it got a ULPMark-CM score of 170 ...

Dutch test gear maker TiePie Engineering has introduced a module that can wirelessly time-synchronise and remotely access multiple instances of its PC oscilloscopes. ‘Wireless multi instrument synchronization module’ WCMI-8 can synchronise series 5 and 6 of both the company’s WiFiScope and Handyscope instruments, at up to 400m range “combining them to a single instrument”, it said. The 868MHz module is ...
