3U rack mount takes up to 12 NVIDIA Jetson Nano/Xavier NX boards

Myelectronics.nl has launched a 19-inch 3U rack mount taking up to twelve NVIDIA Jetson Nano or Jetson Xavier NX boards building on its experience with rack mount for Raspberry Pi introduced last year. The new model also includes front removal mounting systems so that you can replace a Jetson board without having to completely remove the rack mount, and even without having to power off the remaining boards since the boards would have to be powered from the DC jack or (not recommended) the Micro USB port on the front panel. PoE is probably not an option, albeit available on the Nano board, due to mechanical constraints. Specifications listed for the rack mount: Supported SBCs NVIDIA Jetson Nano 2GB Developer Kit NVIDIA Jetson Nano Developer Kit NVIDIA Jetson Xavier NX Developer Kit 12x front-removable trays with screw set, fast click buttons for easy removal Dimensions – 13.5 cm (H) x […]

Arm PSA Level 3 certified Sub-GHz wireless SoCs support Amazon Sidewalk, mioty, Wireless M-Bus, Z-Wave…

Silicon Labs has announced two new sub-GHz wireless SoCs with EFR32FG23 (FG23) and EFR32ZG23 (ZG23) devices adding to the company’s Gecko Series 2 Cortex-M33 platform. Both FG23 and ZG23 support up to one mile (~1.6 km) wireless range, 10+ year battery life on a coin-cell battery, are certified with Arm PSA Level 3 security, and support “advanced wireless technologies” such as Amazon Sidewalk, mioty, Wireless M-Bus (WM-Bus), Z-Wave, and proprietary IoT networks. Silicon Labs explains the chips’ ultra-low transmit and receive radio power (13.2 mA TX at 10 dBm, 4.2 mA RX at 920 MHz) and RF implementation (+20 dBm output power and -125.3 dBm RX at 868 MHz, 2.4 kbps GFSK), makes the long-range and long battery life possible. The ZG23 is designed for Z-Wave applications with Long Range and Mesh connectivity and can be integrated into either end devices or gateways. The company is also working on ZG23-based […]

TVMosaic CE (Community Edition) server released as open source by DVBLogic

TVMosaic (formerly DVBLink) TV/PVR-server application has been released as a cross-platform open-source software, following the closure of DVBLink business last year. It used to be a commercial solution with support for digital TV tuners, live TV watching, PVR functions, DLNA, and more, and there was also a PVR client for Kodi that was part of the list of support PVR clients like TvHeadEnd. DVBLogic did not release the full source code due to licensing requirements, and instead, released the code for TVMosaic Community Edition (CE) server on Gitlab under an MIT license. Some of the missing features include: The Licensing engine since the server is now open-source DLNA server TVAdvisor electronic program guide (EPG) DVBLogic TVButler USB tuner support except in Windows TVMosaic is a cross-platform solution and is supposed to work on Windows 7 or higher, Ubuntu 16.04 LTS 64-bit or higher, Debian 9.1 64-bit or higher, MacOS, 10.12 […]

cuplTag battery-powered NFC tag logs temperature and humidity (Crowdfunding)

Temperature and humidity sensors would normally connect to a gateway sending data to the cloud, the coin-cell battery-powered cuplTag NFC tag instead sends data to your smartphone after a tap. CulpTag is controlled by an MSP430 16-bit microcontroller from Texas Instruments which reads and stores sensor data regularly into an EEPROM, and the data can then be read over NFC with the tag returning an URL with the data from the sensor and battery, then display everything on the phone’s web browser (no app needed). cuplTag specifications: MCU – Texas Instruments MSP430FR2155 16-bit microcontroller @ 24 MHz Storage – 2K bytes EEPROM part of NT3H2111 for up to 188 temperature & humidity data points or 376 temperature-only data points Connectivity – Passive NFC, tap-to-read via NXP NT3H2111 NFC tag Sensors – HDC2021 temperature and humidity sensors Measurement interval – 3 minutes to 65535 minutes (Default: 10 minutes) Battery – CR1220 battery […]

A first look at Microchip PolarFire SoC FPGA Icicle RISC-V development board

Formally launched on Crowd Supply a little over a year ago, Microchip PolarFire SoC FPGA Icicle (codenamed MPFS-ICICLE-KIT-ES) was one of the first Linux & FreeBSD capable RISC-V development boards. The system is equipped with PolarFire SoC FPGA comprised a RISC-V CPU subsystem with four 64-bit RISC-V (RV64GC) application cores, one 64-bit RISC-V real-time core (RV64IMAC), as well as FPGA fabric. Backers of the board have been able to play with it for several months ago, but Microchip is now sending the board to more people for evaluation/review, and I got one of my own to experiment with. That’s good to have a higher-end development board instead of the usual hobbyist-grade board. Today, I’ll just have a look at the kit content and main components on the board before playing with Linux and FPGA development tools in an upcoming or two posts. Microchip PolarFire SoC FPGA Icicle Unboxing The board […]

Intel Seamless Update to enable BIOS/UEFI firmware updates without a reboot

Intel Seamless Update - MM Runtime Update System

Updating the BIOS/UEFI binary usually requires a reboot, but Intel is working on changing that, at least on Linux servers for now, with the Intel Seamless Update aiming to carry out system firmware updates (e.g. UEFI) at run-time without having to reboot, a bit like what Canonical does with the Ubuntu Livepatch service, but at a lower level in the software stack. Intel submitted a patch that “Introduces Platform Firmware Runtime Update and Telemetry drivers” to the Linux kernel mailing list a couple of days ago with the description reading in part: High Service Level Agreements (SLAs) requires that the system runs without service interruptions. Generally, system firmware provides runtime services such as RAS (Reliability, Availability and Serviceability) features, UEFI runtime services and ACPI services. Currently if there is any firmware code changes in these code area, the system firmware update and reboot is required. Example of bug fix could […]
