R-BOX Pro Octa-core Android TV Box Comes with 3GB RAM, Pre-sells for $83

The vast majority of TV boxes on the market only come with 1 or 2GB RAM, although some Rockchip RK3288 based devices ship with up to 4GB RAM, such as Nagrace HPH NT-V6, but so far the maximum I could see only 64-bit ARM platforms was 2GB RAM. R-BOX Pro changes that with an Amlogic S912 processor with 2 or 3GB RAM and 16GB flash. R-BOX Pro specifications: SoC – Amlogic S912 octo-core ARM Cortex A53 processor @ up to 2.0GHz with ARM Mali-820MP3 @ up to 750MHz System Memory – 2 or 3 GB DDR3 Storage – 16GB eMMC flash + micro SD slot up to 32GB Video Output – HDMI 2.0a with HDR and CEC support up to 4K @ 60 fps, and AV port for composite output Audio Output – HDMI, AV (stereo audio), and optical S/PDIF Video codecs – VP9-10 profile 2 up to 4K @ […]

Allwinner A64 based Pine A64 and Banana Pi M64 Boards Can Now Run Windows 10 IoT Core

Windows IoT is a version of Windows 10 that’s optimized for smaller devices with or without a display, and was fist released for Raspberry Pi 2 and MinnowBoard MAX. Since then a few more boards are now officially supported, including DragonBoard 410c, and Raspberry Pi 3. But there’s been some recent developments as two Allwinner A64 64-bit ARM boards are now supported according to two wiki entries (here and there) explaining how to run a simple Csharp sample on Windows 10 IoT Core on either Banana Pi M64 or Pine A64 boards. The guide shows how to configure Azure IoT Hub, register the IoT device, and build and deploy Azure IoT SDK on the board. But basically if all you want to is to run Windows IoT core on either board, you’ll need to download either: Windows 10 IoT Core for Banana Pi M64: Windows10IoT_BPI-M64.ffu (Link removed as Microsoft does […]

Ubuntu 16.04.1 ISO Images Released for Intel Atom Bay Trail & Cherry Trail Compute Sticks

Canonical has recently released Ubuntu 16.04.1, which is now considered stable enough to update from Ubuntu 14.04.04 LTS, and while I could do that easily on my main machine using update-manager, upgrading to Ubuntu 16.04 on Intel Atom “Bay Trail” and “Cherry Trail” devices is a bit more complicated if you need audio & wireless networking (WiFi/Bluetooth) support since the kernel needs to be patched, and on top of that recent Linux kernels are not stable on such platforms without some extra hacks. Linuxium has done all the hard work, and created Ubuntu 16.04.1 ISO images for Intel Atom Compute Sticks with working audio, WiFi, Bluetooth, and “C-state” patchsets to avoid freezes. The images may also work on other devices, but this has not been tested so far. If you want to give it a try, you can download ubuntu-16.04.1-desktop-linuxium-ics.iso, and flash it to a USB drive with Rufus (Windows) […]

SolidRun ClearFog Base is a $90 Router/Networking Board with USB 3.0, M.2, mSATA, and Gigabit Ethernet Support

SolidRun introduced ClearFog Pro and Base board based on Marvell Armada 380/388 processor at the end of last year, but at the time, only the higher-end ClearFog Pro board was available for $170 and up. Now the company has officially launched the cheaper ClearFog Base board based on the same processor, two Gigabit Ethernet RJ45 ports, one SFP cage, a USB 3.0 port, an M.2 slot, mPCIe expansion slot, and more.

What’s the Cheapest MCU? My Try: Holtek HT48R002 8-bit MCU Selling for $0.085

Somebody asked what was the cheapest MCU (Microcontroller) available on Google+, so I thought it would be fun to find the cheapest one regardless of specifications. It turns out there an older thread with this very question on StackExchange, and at the time (2011) Microchip PIC10F200 8-bit MCU with 256B RAM in SOP-23 package was the cheapest one among the answer, and somehow the price has not changed as it’s still $0.32 per unit for 1k orders. Not a bad price, but back in the days when I wrote on CD and DVD players, we had some price pressure from customers, so we looked for a cheaper microcontroller, and ended up using Holtek because of the competitive pricing. We suffered a bit during development due to incomplete documentation but eventually did the job. Anyway, I went to the Holtek website and found a “cost-effective I/O MCU” category, and HT48R002 appears […]

Ipega PG-9057 is a Bluetooth Gaming Gun for Android & iOS Smartphones, TV Boxes, Computers, etc…

I first came across Ipega brand when I reviewed E-Box T8-4 TV box which included Ipega PG-9028 Bluetooth game controller, which also serves as an handle for your smartphone, so that you can easily play game on your Android smartphone while holding the gamepad. That kind of controller is now pretty common, but Ipega 9057 might be a little less common as instead of a gamepad, a gun carries your smartphone instead making it suitable for first person games such as Dead Trigger, Shadowgun, or Modern Combat. PG-9057 gun specifications: Connectivity – Bluetooth 3.0; 8 meters range Stand – 45 to 95mm for smartphones with up to 6″ displays USB – 1x micro USB for charging Controls – Various buttons and joysticks (See graph below) Misc – LED for battery level, vibration motor, reset pinhole Battery – Built-in Lithium 600mAh; up to 25 hours play time; up to 2 hours […]

Embedded Android (Marshmallow) and Brillo / Weave Internals Presentation Slides

Karim Yaghmour – founder of Opersys, a company specializing in Embedded Linux and Android training and development – is currently at Android Devcon 2016 were he gave a full day Embedded Android Workshop on August 1st, as well as a separate 1+ hour talk about Brillo/Weave internals on August 2, and more talks scheduled on the next two days about Android memory management, debugging and development, and Project Ara. He has just released the presentation slides on Slideshare, with the first “Embedded Android Workshop with Marshmallow” presentation totaling 175 pages, and dealing with Linux and Android concepts, overall architecture, system startup, the Linux kernel, hardware support, native user-space, Java for Android, JMI, AOSP, and more… The second presentation is much shorter with 29 slides, and deals specifically with Brillo / Weave internals including Embedded Linux, Android, Binder, DBUS, HAL, the source tree architecture, and so on. While you’d probably learn […]

How to Set an Android TV Box Video Output to Portrait Mode

Most buyers who buy an Android TV box just want to use it to watch videos, browse the web, play games, and so on, so landscape mode seems to be the best choice, and the orientation option in the firmware is often disabled. However, TV boxes can also potentially be used as digital signage players, which may require landscape or portrait modes if the screen is positioned vertically. Since I’ve just been asked that question, I’ve checked for a solution, and luckily there’s an app called Set Orientation that does the job. [Update August 2021: The app has been removed from the Google Play store, it might be worth trying Screen Rotation Control app instead] When you first start the app, it will show the option “Disabled”, but you can click on the arrow to reveal more options, and select Portrait to rotate the screen. In case the screen is […]
