Amlogic S922X Digital Signage Board Comes with HDMI, LVDS, V-by-One, and eDP Video Interfaces

Thanks to its 4K video playback and output capability and high-speed interfaces such as PCIe, USB 3.0 and Gigabit Ethernet, Amlogic S922X is a suitable processor for 4K digital signage players. One way is to get a TV box optimized for signage applications such as Rikomagic MK25, but if you want to integrate a board into your own display, XYT-6689 SBC may be an interesting option with LVDS, V-by-One and eDP (embedded DisplayPort) display interfaces, as well as many other features. XYT-6689 S922X digital signage board specifications: SoC – Amlogic S922X hexa-core big.LITTLE processor with 4x Arm Cortex A73 cores @ up to 2.0 GHz, 2x Arm Cortex A53 cores, Arm Mali-G52MP6 (6EE) GPU; 12nm manufacturing process System Memory – 2GB or 4GB LPDDR4 Storage – 16GB to 64GB eMMC flash, microSD card slot up to 128 GB; maybe SATA (unsoldered “laptop” SATA interface on the backside of the board) […]

DragonBoard 845c Android (AOSP) Reference Board Supports Open Source Graphics, Mainline Kernel

Besides the obvious Google Pixel and Nexus devices supported by AOSP (Android Open Source Project), we previously covered some single board computers that were also officially supported by the project with Hikey and Hikey 960 Android reference boards. Linaro Consumer Group (LCG) has just written about Qualcomm Snapdragon 845 based Dragonboard 845c board. It has been now an official Android reference board for a few months now, and it is the first such board with an open-source graphics stack thanks to Freedreno graphics driver and mesa framework. Since no proprietary blobs are required, the board’s full functionality can also be upstreamed into the mainline kernel, and Linaro currently uses the board as a test target for validating the mainline kernel and stable updates. Here’s a reminder of the board’s hardware specifications: SoC – Qualcomm Snapdragon 845 with 8x custom 64-bit ARMv8 CPUs up to 2.8 GHz, Adreno 630 GPU with […]

CircuitBrains Deluxe is a Tiny, CircuitPython-compatible Module (Crowdfunding)

There are plenty of boards with Adafruit’s CircuitPython support, but Microchip SAMD51 powered CircuitBrains Deluxe is a little different since it’s a module with castellated holes that make it easy to solder to your own baseboard or integrate into a space-constrained product. CircuitBrains Deluxe specifications: MCU – Microchip/Atmel ATSAMD51J19 32-bit ARM Cortex M4 microcontroller @ 120 MHz with 192 KB SRAM, 512 KB Flash Storage – 8 MB Quad SPI Flash I/Os via 48x through holes and castellated holes around the module GPIO (13 Analog, 2 of which are DAC capable, and 19 Digital) SPI, I²C, UART SWD programming/debug interface USB D- & D+ Power Supply Voltage – 5V Output – Onboard 3.3 V 600 mA Linear Regulator (LDO) connected to 3V3 pin Dimensions – 29 x 29 x 3.5 mm The module comes preloaded with CircuitPython, a fork of MicroPython maintain by Adafruit. You can just connect the board […]

Beware of Defective, Wrongly Manufactured IR Thermometers

There is a lot of demand for medical supplies and equipment due to COVID-19. IR Thermometers are used to check the temperature of people before entering a building for instance and are also in short supply. So factories are frantically mass-producing everything they can from face masks to IR thermometers, and it looks like some may forgo quality control. The latter are very hard to find in Thailand, but one person managed to purchase an IR thermometer online and decided to open it… [Update April 16th 2020: The Facebook video has been taken down, but still available on Youtube] This Heaco MDI908 medical thermometer’s infrared board is not connected to the mainboard, so it “works” even without the IR sensor… This takes “non-contact infrared thermometer” to a whole new level 🙂 I can see Kaidee (Thailand’s eBay) had some listed a few days, but the pages have since then been […]

4K Digital Signage Player Drives up to 4x 4K Displays with AMD Ryzen Embedded V1000 SoC

AMD Ryzen Embedded V1000 Digital Signage

We’ve covered plenty of AMD Ryzen Embedded V1000 SBC‘s, as well as some mini PC‘s, but the processor’s multimedia capabilities make it an ideal candidate for advanced digital signage players capable of driving multiple 4K displays. Axiomtek leveraged those capabilities in DSP600-211 4K digital signage player that offers four HDMI ports driving up to four 4K displays, as well as dual Gigabit Ethernet. Axiomtek DSP600-211 4K digital signage specifications: SoC (one or the other) AMD Ryzen Embedded V1605B quad-core/octa-thread processor @ 2.0GHz / 3.6 GHz (Boost) with AMD Radeon Vega 8 Graphics; 12-25W TDP AMD Ryzen Embedded V1807B quad-core/octa-thread processor @ 3.35GHz / 3.8 GHz with AMD Radeon Vega 11 Graphics; 35-54W TDP System Memory – 2x DDR4-2400 SO-DIMM up to 16GB Storage – 1x M.2 Key M 2280 (SATA) and 1x M.2 Key M 2280 (NVMe) Video Output – 4x HDMI 2.0 ports up to 4K @ 60 Hz […]

MIOTY Silicon Vendor Agnostic, Scalable LPWAN Standard to Take on LoRaWAN, NB-IoT

[April 6th update: The article was updated to reflect Fraunhofer invented the technology] There are plenty of LPWAN (Low Power Wide Area Networks) standards designed for low power, low bitrate and long-range connectivity with the most popular currently being NB-IoT and LoRaWAN. But Texas Instruments has joined other smaller companies (Fraunhofer, Ragsol, STACKFORCE, WIKA…) to form the MIOTY alliance in order to develop and promote a new LPWAN standard operating in the sub-GHz range called MIOTY. Texas Instruments explains MIOTY was born due to a lack of scalability and robustness (interferences issues) of current LPWAN solutions. But just like other similar low power WAN standards, it aims to support long-range while achieving long battery life, but MIOTY is also supposed to help IoT developers mitigate performance degradation in high-node-count networks. MIOTY works in the same license-free bands (868 MHz, 915 MHz …) as LoRa radios with no costs involved to […]

Rosetta@Home Now Supports 64-bit Arm SBC’s and Servers in the Fight against COVID-19

Folding@Home and Rosetta@Home projects aim to perform biomedical research using the computing power of volunteers. Basically, you just need to install a program on your computer, and it will use idle computing power to perform complex calculations without slowing down your computer as long as you are not short in RAM. The projects are now working on COVID-19 to understand how SARS-CoV-2 protein is structured which could help find a cure. The programs have been available for Windows, Linux and Mac OS on 32-bit and 64-bit x86 targets for years, but very recently Rosetta@Home has been made available for 64-bit ARM targets so people can also run BOINC program on Arm Linux SBCs such as Raspberry Pi 4, NVIDIA Jetson Nano, or Rock64, or even powerful Arm servers to help with Rosetta@Home project’s COVID-19 research. As explained in an article on miniNodes, you’ll need a board with at least 2GB […]
