$25 TinyScreen is an OLED Display for TinyDuino Arduino Compatible Board (Crowdfunding)

Back in 2012, Tiny Circuits launched a Kickstarter campaign for TinyDuino, an Arduino compatible board that’s… tiny, based on Atmel Atmega328P, and supports tiny stackable shields in a similar fashion to Microduino (launched in 2013). The campaign was successful, and the company is now back on Kickstarter with TinyScreen, an OLED display that can be stacked on top of TinyDuino to create a smartwatch, a minuscule gamepad, smart glasses, and more. TinyScreen technical specifications: 96×64 OLED display, 16-bit color depth 0.96″ (24.4mm) viewable area Software controllable backlight (OLED brightness) Power down mode Four push buttons along the sides (connected to IO pins) SPI interface for display Power Supply – 3.0V to 5.5V operation (higher voltages supported with TinyShield power regulator) Power Consumption – 20 – 45mA max supply current (depending on brightness) Dimensions – 25.8mm x 25.0mm Programming of TinyDuino can be done through a web interface for Arduino called […]

MatchStick’s Firefox OS Firmware Ported to MK808B mini PC

MatchStick is an HDMI Stick running Firefox OS and designed to stream online video, mirroring browsers, etc.. which makes it very similar to a Chromecast, even using the same DIAL protocol. The hardware is based on Rockchip RK3066, and Mozilla released an SDK for the device. Since there are quite a few Rockchip RK3066 TV sticks out there, BalintBanyasz announced he ported MatchStick’s firmware to MK808B (with RK903 Wi-Fi module), and has now provided the firmware and instructions on Freaktab. The firmware is based on Linux kernel 3.0.36+ used in Android 4.2.2. Once you’ve flash the firmware (matchstick-flingone-b2g2.0-201409281739-mk808b.img.7z) to MK808B, and installed MatchStick app / add-on in your Android device or Firefox Browser (iOS app coming) soon, you can “fling” a YouTube video from your phone / browser to your TV through MK808B as follows: Open MatchStick app on your phone in order to detect the hotspot (MatchStickXXXX) created by […]

LS1021A-IOT IoT gateway Specifications: SoC – Freescale QorIQ LS1021A dual core Cortex A7 communication processor @ 1 GHz (5,000 coremarks) MCU – Freescale Kinetis K20 Cortex M micro-controller System Memory – 1 GB DDR3L Storage – 1 Gb QSPI NOR Flash, SDHC slot (up to 32 GB) populated with a 4GB SD card, 1x mSATA 3 slot Connectivity – 6x Gigabit ports via SGMII (Serial Gigabit Media Independent Interface) and […]

Can Rockchip RK3288 Android TV Boxes Play Videos at True 4K UHD / 2160p Resolution?

[Update 2: Now that I have a 4K TV, I’ve redone the test myself, and Rockchip RK3288 can play 4K videos properly. The mistake was to use Software decode in MX Player which renders to the framebuffer instead of the video buffer. Visit the post entitled 4K Output and Video Playback Capability Tested on 6 ARM based mini PCs and Boards for details.] [Update 1: The post has now been updated, after it was clear one of MX Player options was misunderstood. The conclusion remains the same] Over the last few years there have been complains about Android TV boxes decoding 1080p video, rendering them to a 720p frame buffer, and upscaling them back to 1080p resolution for video output, so you ended up playing 1080p videos at a real 720p resolution. I never investigated the issue in details, and thanks to new media players now coming with a 1080p […]

KDDI Unveils Tiny BLE/Zigbee Development Board Running Mozilla Firefox OS

KDDI has recently announced Open Web Board, an HDMI TV stick powered by Rockchip RK3066, and running Firefox OS, just like the recently announced MatchStick. The board is however aimed at embedded and web developers who want to create apps for Firefox OS, and interface with external devices over Bluetooth Low Energy or Zigbee (optional module) communication, optionally using Gluin, a web based graphical “application development tool that enables simple linking programming between electronic devices”. Open Web Board specifications: SoC – Rockchip RK3066 dual core Cortex A9 processor @ 1.6 Ghz with Mali-400 MP4 GPU System Memory – 1 GB RAM Storage – 8 GB flash Video Output – HDMI USB – 1x USB 2.0 host port, 1x micro USB for power Connectivity – 802.11 b/g/n Wi-Fi (AP6210 module), Bluetooth 2.1 (HFP/A2DP/AVRCP)/4.0 GATT. and optional Zigbee via external module Dimensions – Small This dongle runs Firefox OS 1.4. KDDI showcased […]

Unboxing of MXQ S85 Android Media Player Powered by Amlogic S805 Processor

Gearbest sent me MXQ S85 Android media player powered by Amlogic S805 quad core processor with 1GB RAM, 8GB internal storage, and Ethernet/Wi-Fi/Bluetooth connectivity. MXQ S85 looks very similar to EM6Q-MXQ, another Amlogic S805 based Android STB, which I reviewed last week, but these are two distinct hardware platforms. Today, I’ll take some pictures of the devices, and the board to see which components are used, and who made the board, and I’ll write a full review in a few days. MXQ S85 Pictures I’ve received the parcel via DHL in the nameless package below where they just indicate it’s and Android TV box with a quad core processor, quad core GPU, pre-loaded with XBMC, and supporting HEVC / H.265 The package contains the box, HDMI and AV cables, an OTG adapter, a 5V/2A power supply, an IR remote requiring two AAA batteries, and a user’s manual in English. The […]

Current Performance and Stability Issues on AllWinner A80 OptimusBoard Development Board

Sine A80 OptimusBoard is the first ARM hardware that supports both USB 3.0 and Gigabit that I’ve ever owned, so I though it might be interesting to see what performance I could get with a USB 3.0 hard drive through the USB 3.0 OTG port of the board. For testing purpose, I bought a USB 3.0 OTG adapter on Ebay, but I did not look closely enough as it turned out to be only a USB 3.0 OTG to USB 2.0 female adapter capable of USB 2.0 speeds… Kind of useless item since you can plug a standard USB 2.0 OTG adapter into a USB 3.0 OTG receptacle. But I tried my hard drive anyway, and quickly realized write performance was very poor at 3 MB/s on the NTFS partition, whereas most other devices can handle at least15 MB/s, and usually over 25 MB/s. So I contacted Allwinner with this […]

How to Upgrade Allwinner A80 OptimusBoard Firmware

After informing Allwinner I had some rather slow write speed (3MB/s) to the NTFS partition of my USB drive on my A80 OptimusBoard, they kindly provided a new compressed Android firmware image (sun9iw1p1_android_optimus_v1.2_20140930.img.7z) with some NTFS optimizations that can be downloaded from baidu (password: x2tz), mega.co.nz or simos.info (please only use this link, if the other two do not work as it’s a private website and monthly bandwidth may be limited). I vaguely remember tools like LiveSuit (Linux) or PhoenixSuite (Windows), and I ended up on sunxi-linux Livesuit wiki as I’m running Ubuntu 14.04 on my PC, but you should be able to flash the firmware with PhoenixSuite if you run Windows. The instructions below can also be used for other Allwinner based devices. First you need to install LiveSuit, and build Allwinner USB drivers as follows:

In order to use LiveSuit as a normal user, you also have […]
