Smarthon Smart City IoT Starter Kit review

SMARTHON Smart City IoT Starter Kit for micro:bit is an educational kit for 10+ years old teaching basic projects from turning an LED to more complex projects with multiple sensors, IFTTT integration, and mobile app development. The company sent us a sample of the Start Kit along with a BBC Micro:bit board for review, and we’ll report our experience with the kit in this review. Unboxing of SMARTHON Smart City IoT Starter Kit for micro:bit The package I received includes the SMARTHON Smart City IoT Starter Kit for Micro:bit and a BBC Micro:bit V2 board since it’s not included in the starter kit. The bottom side of the package lists the main components and features a QR code pointing to the product page. The package includes cardboard and wooden models, various cables, a 180° servo, a screw set, a city map, the Smarthon IoT:bit carrier board for the BBC Micro:bit, […]

NXP MCX L14x and MCX L25x ultra-low-power Cortex-M33 MCUs target energy harvesting and battery-powered devices

MCX L series chip

NXP Semiconductors has launched the MCX L series of ultra-low-power Arm Cortex-M33 MCUs with the MCX L14x and MCX L25x SKUs. The new series offers similar peripherals as the rest of the MCX portfolio but uses a new “power management architecture that supports always-on, battery-powered applications” The MCX L series uses a dual domain architecture, with “real-time processing and ultra-low-power sensing functions in a single device.” The Arm Cortex-M33 core supports real-time processing functions while the Arm Cortex-M0+ core offers always-on operation in the ultra-low-power sense domain. The new microcontrollers reportedly use three times less power than their predecessors. The ultra-low-power series is targeted at energy-constrained applications, powered by a battery, ultracapacitor, or power harvesting circuit. These include building control, industrial sensing, smoke and fire alarms, flow meters, smart appliances, and motion detectors. NXP MCX L14x and L25x specifications: CPU Main core: Arm Cortex-M33 microcontroller @ up to 96 MHz […]

Seeed Studio XIAO Plus series adds more GPIOs through castellated holes

SeeedStudio XIAO Plus Series

In response to community feedback for more I/O options, Seeed Studio has recently launched the Seeed Studio XIAO Plus series with 23 castellated mounting pins (20 GPIOs, 3 power pins) and improved back solder points, improving compatibility with carrier boards for complex projects. The new series includes the XIAO ESP32S3 Plus, XIAO nRF52840 Plus, and XIAO nRF52840 Sense Plus which are direct upgrades of the XIAO ESP32S3, XIAO nRF52840 BLE, and XIAO nRF52840 Sense boards. The new design allows for easier assembly and scalable production, with double the I/O options. XIAO ESP32S3 Plus The Seeed Studio XIAO ESP32S3 Plus is a compact development board with a total of 23 pins on the board out of which 11 are through-hole GPIO pins 9 additional SMD castellations GPIO pins and 3 through-hole are power pins. The board is built around an ESP32-S3 MCU so it has 2.4GHz WiFi and BLE 5.0 connectivity. Other […]

GuRu’s modular wireless power transfer system can power a drone indefinitely

GuRu wireless power transfer System

California-based company GuRu Wireless has recently developed and showcased a scalable and modular wireless power transfer system that is capable of delivering power to a high-power device up to several kilowatts, such as a drone, from up to 30 feet away (a little over 9 meters). They also mention that the system can power low-power devices, like LEDs and consumer electronics, over distances of several kilometers. It’s quite an extension to the GuRu’s desk-range wireless power evaluation kit we covered in 2020. The system uses 24 GHz high-frequency millimeter-wave radio signals to deliver energy over long distances without needing batteries or tethered systems. GuRu’s system uses a phased array transmitter with proprietary RFICs, to precisely deliver power to the receiver called the Recovery Unit (RU). In a recent demonstration video, GuRu Wireless showcased their wireless power transfer system by powering a drone from 30 feet away, operating it continuously for […]

NanoCOM-ADN – A COM Express Type 10 Module based on Intel Alder Lake-N SoC

AAEON NanoCOM-ADN COM Express module

AAEON NanoCOM-ADN is a compact (84 x 55mm) COM Express Type 10 module based on Intel Alder Lake-N SoCs, namely Processor N50/N97, Atom x7425E, or Core i3-N305 that adds another option to the SMARC, Qseven, and COM Express Type 6 modules offered by the company with the same processors.

Eclipsa Audio is an open, royalty-free alternative to Dolby Audio

Eclipsa Audio

Samsung announced Eclipsa Audio 3D technology, a royalty-free alternative to Dolby Audio, would be integrated into TVs and Soundbars in its 2025 lineup at CES 2025. The press release explains the 3D audio technology was developed in partnership with Google and that “Eclipsa Audio allows creators to adjust audio data such as the location and intensity of sounds, along with spatial reflections, to create an immersive three-dimensional sound experience”. Like 90% of announcements at CES 2025, Eclipsa Audio appeared to be mostly fluff. I also noticed it was developed through the Alliance for Open Media which manages the now-widely-used AV1 video codec, but a search for Eclipsa did not return anything. Luckily the “Arm Editorial Team” saved the day with an interesting article published a couple of days ago with more information about Eclipsa Audio. So let’s have a look. Eclipsa Audio is a multi-channel audio surround format that leverages […]

Tactility “operating system” for the ESP32 microcontroller family supports built-in and external applications

Tactility devices with logo

Tactility is an operating system that runs on the ESP32 microcontroller series. Created by Dutch software developer, Ken Van Hoeylandt (also known as ByteWelder), Tactility is a project one year in the making inspired by the Flipper Zero and its application platform. The ESP32 operating system can run built-in apps and helper services from flash storage as well as external applications from an SD card. It leverages the Espressif ELF(Executable and Linkable Format) loader to load ELF files from external storage to the executable memory area. Tactility is built to run on any ESP32-based device with a touchscreen since drivers (display, touch, and SD card) can be implemented for any hardware. ESP32-S3 devices are “the best option” due to their performance and larger memory. The LILYGO T-Deck series is highly recommended for its onboard keyboard and sizable display. Preset configurations are available for the LILYGO T-Deck Plus, LILYGO T-Deck, M5Stack […]
