Zidoo H6 Pro 4K HDR TV Box with Allwinner H6 SoC Launched for $99

When I first wrote about Zidoo H6 Pro TV box powered by Amlogic H6 “6K” media processor last week, I expected the launch to take place in several weeks or months, as no other company listed their Allwinner H6 TV box(es) on Alibaba. So today, I was surprised to find out GearBest and GeekBuying are both taking pre-orders for $99, with shipping expected around August 11 – 15 according to the page on GearBest, and in around 3 days according to GeekBuying. The specifications have not changed since last week…: SoC – AllWinner H6 quad-core ARM Cortex-A53 processor up to 1.8GHz with Mali-T720MP2 GPU System Memory – 2GB DDR4 Storage – 16GB eMMC flash, micro SD card reader up to 32 GB Video Output – 1x HDMI 2.0a up to 4K @ 60hz with HDR support, AV port (composite) Video Playback Support H.265/HEVC Main/Main10 profile @ level 5.2 high-tier up to […]

ROCK64 Board Review – Part 2: Quick Start Guide with Ubuntu 16.04.3 MATE, Multimedia Features, Some Benchmarks

Pine64 ROCK64 is the first maker board based on Rockchip RK3328 processor, and is potentially interesting for various applications including network storage thanks to USB 3.0 and Gigabit Ethernet, multimedia applications with 4K HDR video support, as well as other applications requiring I/Os. I’ve already tested Rock64 board with Android 7.1 operating system, so today I’ll report by finding and experience with Ubuntu 16.04.3 with MATE desktop. Selecting and Flashing a Linux Image You’ll find several operating systems in the Wiki, but you’ll also find more cutting edge images in ayufan’s github. But first let me explain some vocabulary used for Pine64 firmware files: Engineering version – Becomes with release build based on the stock build develop by Pine64 and the SoC vendor. It’s supposed to be more stable, but get less updates Community versions (currently managed via ayufan) are more frequently updates, and comes with more recent features. You’ll find […]

Rockchip Sapphire is a $75 Rockchip RK3399 Development Board

While there are several Rockchip RK3399 boards on the market, I’d still recommend to use Firefly-RK3399 development board for Android and Linux based projects since they have decent documentation, and the board has been around for several months now. Price is a little high however, as it starts at $159 on Amazon US. There’s been other boards like 9Tripod RK3399 that’s a little cheaper, but mostly targeting the Chinese market, and Shenzhen Xunlong is working on their own RK3399 board and module, but it’s not available yet. Nightseas user bought another board called Rockchip Sapphire on Taobao for just 500 RMB (~$75 US), and reported his findings on Armbian forums. Rockchip SAPPHIRE board specifications: SoC – Rockhip RK3399 hexa-core big.LITTLE processor with two ARM Cortex A72 cores, four Cortex A53 cores, and an ARM Mali-T860 MP4 GPU System Memory – 4 GB LPDDR3, dual channel Storage – 8 GB eMMC […]

Intel Mini PCs Sold with Ubuntu on Aliexpress

Many low power mini PCs equipped with Intel Bay Trail, Cherry Trail, Braswell, or Apollo Lake processors have been launched over the years, but most of those come pre-loaded with Windows 10, and many readers of this blog prefer to run a Linux distribution. It’s usually possible to install Ubuntu by yourself, but not always, and when you buy a Windows 10, this increases the price by several dollars (around $20). The ideal case would be to get such low power, low cost mini PCs pre-installed with a recent version of Ubuntu, without having to worry (too much) about hardware support, nor having to pay the “Windows tax”. MeLE used to sell Ubuntu mini PCs on Aliexpress, but sadly not anymore, so I went to Aliexpress to look for those Ubuntu mini PCs, and BBen offers three operating systems options for some of their systems with “Windows 10 Activated”, “Windows […]

Rockchip Has Setup an Official Open Source Website with Software & Hardware Documentation, Source Code

As a young engineer, I first understood the importance of good documentation thanks to an incomplete Holtek MCU datasheet that made us waste weeks of development, and the value open source software thanks to Sigma Designs’ SDK that was full of binary blobs with our applications often crashing inside those, leading to software development delays, especially since we had access to limited support. More recently, if you ever worked with the most popular Chinese processors found in ARM Linux development board, usually made by Allwinner, Amlogic, or Rockchip, you must have gone through roadblocks due to a lack of documentation and software support. So far, Allwinner is purely relying on linux-sunxi community and “leaks” of their documentation and SDKs, while Amlogic has had their “open linux” microsite for several years, but you won’t find complete documentation like technical reference manual, schematics, and part of the source code requires you to […]
