Backy is a nRF52840-powered wearable for real-time posture monitoring and injury prevention

TACNIQ Backy is an AI-enabled wearable monitoring device designed to reduce workplace injuries caused by improper lifting and posture, based on a Nordic nRF52840 wireless microcontroller and a 6-point piezo-resistive sensor array measuring direct force sensing. While most ergonomic tools rely on motion tracking or vision-based systems, Backy relies on direct force sensing and embedded AI inference, and the company claims it provides real-time, direct strain detection at a lower cost than competing solutions while keeping costs low and precision high. Backy specifications: SoC – Nordic Semi nRF52840 ARM Cortex-M4 microcontroller with Bluetooth LE 5.0 Data Storage – Onboard, with local/cloud sync options Sensors – 6-point piezo-resistive pressure array + tilt sensing Feedback – 5G-force vibration motor for posture alerts Calibration – Auto-calibrates in ~3 seconds Connectivity – BLE 5.0, USB for charging and updates Features Optional SMS/Telegram supervisor notifications Open API (REST/Tag-based protocols) Security – End-to-end encryption; note: disabled […]

M5Stack Tab5 Review – Part 1: Unboxing, teardown, and first try of the ESP32-P4 and ESP32-C6 5-inch IoT devkit

I’ve just received a review sample of the M5Stack Tab5 ESP32-P4 IoT development kit, which looks like a small tablet with a 5-inch touchscreen display, a 2MP front-facing camera, an ESP32-C6 WiFi 6, Bluetooth, and 802.15.4 wireless module, and various expansion interfaces. Today, I’ll go through an unboxing, a (partial) teardown, and have a quick try with the default firmware and GUI, before checking out how to program the device in the second part of the review. M5Stack Tab5 unboxing I received the Tab5 in its retail package along with an M5Stack-branded transparent sticky tape roll. Not sure why, but thanks M5Stack, sticky tape is always useful, so appreciated! The bottom side of the package has all the key features and specifications that we already covered in our article about the Tab5. The package contains the Tab5 itself, a 2,000mAh/14.8Wh battery, and a cable with six wires for the ExtPort2 […]

$39 ODROID-C5 is a power-efficient Amlogic S905X5M SBC with 4GB RAM, no heatsink needed

Hardkernel ODROID-C5 is a lower-cost upgrade to the ODROID-C4 SBC with a faster and more efficient Amlogic S905X5M quad-core Cortex-A55 SoC clocked at 2.5 GHz, 4GB DDR4 RAM, and almost the same features as the previous generation Amlogic S905X3 single board computer. That means a microSD card slot and an eMMC flash module socket for storage, HDMI 2.0 video output up to 4Kp60, a Gigabit Ethernet RJ45 port, four USB ports, and the usual 40-pin Raspberry Pi GPIO header. ODROID-C5 specifications: SoC – Amlogic S905X5M CPU – Quad-core Cortex-A55 processor @ 2.5 GHz GPU – Arm G310-V2 GPU @ 850 MHz supporting OpenGL ES 3.2, Vulkan 1.0 and OpenCL 2.0 VPU Video Decoding – 4Kp75 10-bit: AV1, H.265, VP9, AVS2; 4Kp30: H.264 Video Encoding – 1080p30 H.264 System Memory – 4GB DDR4 @ 3200MT/s Storage eMMC module connector with HS400 speed (16, 32, 64GB, 128GB, and 256GB modules available) MicroSD […]

SiFli SF32LB52J big.LITTLE Arm Cortex-M33 Bluetooth MCU powers the Core Time 2 smartwatch

SiFli SF23LB52J is a Bluetooth 5.3 microcontroller part of the SF32LB52x family with two Cortex-M33 in big.LITTLE configuration with a 240 MHz high-performance core for user application/GUI and a 24 MHz low-power core to manage the Bluetooth part. A few months ago, Eric Migicovsky, the founder of the smartwatch company Pebble, and now Core Devices, introduced the Core 2 Duo and Core Time 2 smartwatches running PebbleOS open-source firmware that were mostly relaunches of the never-released Pebble 2 and Pebble Time 2 with some tweaks. We already knew the Core 2 Duo would be based on a Nordic nRF52840 Arm Cortex-M4F microcontroller, however, the one for the Core Time 2 was kept secret. That’s until today, as Eric has just announced that the Core Time 2 would be based on the SiFli SF23LB52J MCU, since the smartwatch required an MCU with more RAM and processing power, and SiFli also offers […]

Root Commit releases free training materials on OpenEmbedded and Yocto using the BeaglePlay SBC

Michael Opdenacker, Founder of Root Commit, has published free and open-source training materials on OpenEmbedded and Yocto using the BeaglePlay SBC powered by a Texas Instruments AM625 processor. If the name rings a bell, it’s because Michael was the founder of Bootlin (previously Free Electrons) before selling the company to employees in 2021. He’s now started a new company called Root Commit, where he continues providing Embedded Linux training and development services. He’s kept the tradition of releasing free training materials, with the latest course being related to Yocto development on the BeaglePlay board. You’ll find resources on the Root Commit website with three files, including 220 pages of lectures, 18 practical labs for the BeaglePlay board and QEMU, and source code/patchsets released under a Creative Commons BY-SA 4.0 license. The course includes an introduction to the Yocto Project 5.0 and Embedded Linux, a Getting Started guide explaining how to […]

PicoEMP – A Raspberry Pi Pico-based open-source electromagnetic fault injector designed for EMFI testing and research

The PicoEMP is a compact, low-cost, open-source electromagnetic fault injector (EMFI) tool developed by Colin O’Flynn for researchers, hobbyists, and educators interested in hardware security. Unlike NewAE’s professional-grade ChipSHOUTER, PicoEMP is a bare-bones device designed to be safe, usable, and most importantly, affordable. Built around the Raspberry Pi Pico, this device generates high-voltage pulses using a transformer circuit (originally for photographic flash charging) to discharge energy from a low-ESR ceramic capacitor into a custom-made coil tip, which creates an electromagnetic field capable of injecting a little bit of power to the internals of the processors such as registers and SRAM. This can be exploited to flip bits and test the robustness of embedded systems against such attacks. ChipSHOUTER-PicoEMP specifications Main controller – Raspberry Pi Pico (RP2040 dual-core Arm Cortex-M0+ MCU @ up to 133 MHz) Purpose – Electromagnetic Fault Injection (EMFI) for testing embedded systems security Components High-voltage pulse generator circuit […]
