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) […]

ODYSSEY-X86J4105800 SBC Combines Intel Gemini Lake SoC and Arduino Compatible MCU

Would it be good to have an all-in-one Windows platform used to both develop Arduino code and run that code to control I/O of your project? Or alternatively, have a single board computer capable of video processing and real-time I/Os? That platform already exists. UDOO X86 II SBC features an Intel Braswell processor combined with an Arduino Leonardo compatible Microchip ATmega32U4 MCU. But there’s now another, more powerful option courtesy of Seeed Studio with the oddly named ODYSSEY-X86J4105800 SBC equipped with an Intel Celeron J4105 quad-core Gemini Lake processor to run Windows 10 or Linux distributions, and a Microchip SAMD21 ARM Cortex-M0+ microcontroller compatible with Arduino Zero. ODYSSEY-X86J4105800 SBC specifications: SoC – Intel Celeron J4105 quad-core processor @ 1.5/2.5 GHz (Turbo) with 12EU Intel UHD Graphics 600 @ 250-750 MHz; 10W TDP System Memory – 8GB LPDDR4 RAM Storage Optional 64GB eMMC flash (fitted to ODYSSEY-X86J4105864 model), 1x SATA III data […]

Google Releases Android 11 Developer Preview – What’s New?

I’ve only just upgraded my Xiaomi Mi A2 phone to Android 10 earlier this week, but Google is already preparing for the next version of the mobile operating system, and the company has already released the first developer preview for Android 11 OS. Enhancements for foldables and 5G, call-screening APIs, new media & camera capabilities, and machine learning are some of the improvements brought to Android 11 so far. Some of Android 11 highlights include: Updates of existing connectivity APIs to take advantage of improved 5G speeds. Dynamic meteredness API to check whether the connection is unmetered in order to offer higher resolution or quality for users who don’t need to pay extra for data Bandwidth estimator API to check the downstream/upstream bandwidth without having to poll the network. Pinhole and waterfall screen support – Pinhole screens are the ones with a round opening for the camera, and waterfall […]

10.3″ E-paper HDMI Display Connects to Raspberry Pi & Jetson Nano SBC’s, Computers

E-paper displays only consume power when updated, work great in bright light, and are easier on eyes when reading text. The downside is the low refresh rate which makes those impractical for videos and games, and most E-paper displays are black and white or with just a few colors. Another hindrance is that most are connected via flat cables for specific display interfaces which may not be the easiest to handle, and you may not be able to easily move the display across platforms if you wish too. Waveshare EINK-DISP-103 10.3″ E-paper display solves this little problem since it should work with any SBC or computer with an HDMI output. EINK-DISP-103 Key features & specifications: 10.1″ e-Paper display, 1872×1404 resolution (225DPI), grayscale (16 shades) Video Input – Mini HDMI port Misc – UPD/RUN switch, contrast adjustment, power indicator, screen refresh button, mode switch button Power Supply – 5V/3A recommended and […]

Raspberry Pi 4 WiFi Fails When Setting HDMI to 2560×1440 Resolution

Raspberry Pi 4 WiFi Fail 2560x1440 Resolution

Enrico Zini was working on a digital signage solution based on Raspberry Pi 4, then he set the video output to 2560×1440, and all hell broke loose. And by that, I mean WiFi stopped working. It was not obvious at first but after a full day of debugging, trying both micro HDMI outputs, different HDMI cables, three different Raspberry Pi boards, different power adapters, Raspbian Buster and Buster Lite, different MicroSD cards… He could reproduce the problem in all conditions, all he needed to do was to set the resolution to 2560×1440, and WiFi would just stop working. Setting the resolution to 2048×1080 or lower, and all WiFi connectivity issues disappeared. He did not test at higher resolutions, and another user reported a similar problem happening at 2.4 GHz, but not at 5 GHz, albeit when setting HDMI output to 1920×1080. So it looks like interference, but as noted by […]

Rock Pi 4C SBC to Support Dual Display Setups via micro HDMI and mini DP Ports

Rockchip RK3399 powered Rock Pi 4 SBC was introduced at the end of 2018 and followed nearly exactly Raspberry Pi 3 Model B form factor just with a more powerful processor, GPU, as well as more memory depending on which model you purchase. But in June 2019, the Raspberry Pi foundation launched Raspberry Pi 4 SBC with a much faster processor and many of the same ports as its predecessor except for support for two HDMI displays via micro HDMI ports. Radxa has now followed suit with Rock Pi 4C which offers two modern video outputs, but with a twist as the upcoming SBC combines one micro HDMI port with one mini DP port. Rock Pi 4C was introduced at the XDC 2019 conference where open-source graphics developers meet, and Radxa was a “supporter”. The company explains Rock Pi 4B uses RK3399’s USB type-C controller for the two USB 3.0 […]

Geniatech ATV1660K TV Box Supports Dual HDMI Output, HDMI Input

There are many applications that may benefit from dual display support from digital signage to healthcare to retail or entertainment either to provide access to two different output for the service provider and customer or simply to mirror content. Most Android TV boxes only come with one display output however, so in most cases, you’d have to switch to an Intel mini PC or add a USB-C display adapter if supported by the hardware. Geniatech ATV1660K TV box supports dual HDMI output out of the box, as well as HDMI input. The Android 5.1 TV box is powered by the time-tested Rockchip RK3288 processor and comes with 2GB RAM and 16GB storage by default. Geniatech ATV1660K specifications: SoC – Rockchip RK3288 quad-core Arm Cortex-A17 processor at up to 1.8GHz, with Mali-T764 GPU System Memory – 2GB DDR3 (1GB optional) Storage – 16GB eMMC flash (4GB-32GB optional), full-size SD card slot […]
