Artway W8 Plus is a $100 Mini PC with HDMI and DisplayPort

May 16th, 2015 4 comments

Most mini PCs with Intel Atom Z3735F only come with HDMI output, while a few others feature both HDMI and VGA like MeLE PCG03, but if you need a cheap mini PC with both HDMI and DisplayPort as found in Intel NUC, Artway W8 Plus is worth a look especially since it sells for just $99 on Aliexpress.

W8_PlusW8 Plus specifications:

  • SoC – Intel Atom Z3735F quad core processor @ 1.33 GHz (Bust freq: 1.83 GHz) with Intel HD graphics
  • System Memory – 2 GB DDR3L
  • Storage – 32 GB eMMC  (16, 64 or 128GB optional) + micro SD card slot
  • Video Output – HDMI 1.4b, and DisplayPort
  • Audio I/F – HDMI, audio out and mic in jacks
  • Connectivity – 10/100M Ethernet, 802.11 b/g/n Wi-Fi (RTL8723BS or AP6330), and Bluetooth 4.0
  • USB – 4x USB 2.0 host
  • Misc – Power Button, RTC
  • Power Supply – 5V/2A
  • Dimensions – 107 x 107 x 25 mm
  • Weight – 200 grams

W8_PLus_HDMI_DisplayPortThe mini PC comes pre-loaded with Windows 8.1 (Which has got to be unlicensed at that price), but you should probably be able to run Linux based operating systems like Ubuntu, especially since there’s now a fix for HDMI audio. The computer supports dual independent displays via HDMI and DisplayPort. W8 Plus ships with an HDMI cable, a user’s manual, and a 5V/2A power adapter. If you plan to connect an external USB hard drive, you may have to replace the latter with a more powerful one (e.g. 5V/3A) to avoid potential stability issues.

Orange Pi Plus (Allwinner H3) Firmware Images and Linux SDK Released

May 12th, 2015 12 comments

Orange Pi Plus is a development board based on the new Allwinner H3 quad core Cortex A7 processor that supports 4K video output and decoding. The boards comes with 1GB RAM, 8GB eMMC, HDMI output, Gigabit Ethernet, Wi-Fi, SATA and more, and sells for $49 on Aliexpress. When I first covered the board in February, it was already listed on Aliexpress, but I could not find any firmware image, or source code, but this has now changed.

There are now four firmware files:

  • Lubuntu_1404_For_OrangePiplus_v0_8_0_.img.xz – Lubuntu 14.04 image
  • Raspbian_For_OrangePiplus_v0_8_0.img.xz – Raspbian for Allwinner H3
  • orangepi-plus-debian-server-card-v0.9.img.xz – A Debian server image
  • sun8iw7p1_android_orangepi-plus_uart0.rar – Android 4.4.2 image that needs to be flash with PhoenixCard in Windows (Linux tools are not working yet)

Beside the firmware images, the company also releases a Linux SDK (h3-lichee-1.0.tar.gz) with Linux 3.4 kernel source code, u-boot, and relevant tools.

I assume these should also work on Orange Pi 2, the low cost version of the board without internal flash, nor SATA, and Fast Ethernet instead of Gigabit Ethernet, which goes for $35 on Aliexpress.

Thanks to Jerome for the tip.

CHIP is a $9 Linux Development Board Powered by Allwinner R8 (Crowdfunding)

May 8th, 2015 45 comments

It’s quite common to find MCU board for less than $10, but if you want to run Linux, you’ll need to spend a bit more, unlessit’s sponsored, and today, the cheapest you can get is probably the $20 Raspberry Pi Model A+, unless you go with some OpenWRT compatible routers. But there’s now a new board in development, called CHIP, with Allwinner R8 Cortex A8 processor, 512MB RAM, and 4GB NAND flash, as well as wireless connectivity, that will bring cost even lower, as you can pledge $9 on Kickstarter to fund its development.

CHIP_Allwinner_R8

C.H.I.P specifications:

  • SoC – Allwinner R8 Cortex A8 processor @ 1 GHz with Mali-400 GPU (Compatible with Allwinner A13)
  • System Memory – 512 MB RAM
  • Storage – 4GB NAND flash
  • Connectivity – 802.11 b/g/n Wi-Fi + Bluetooth 4.0
  • Video Output – 3.5mm jack for composite video and audio (HDMI and VGA available via adapters)
  • USB – 1x USB host port, 1x micro USB OTG port
  • Two expansion headers
  • Power – 5V via micro USB OTG or battery
  • Dimensions – 60 x 40 mm

The board is said to run a Linux distribution featuring the mainline kernel. There’s also some sort of portable gamedpad called Pocket C.H.I.P that integrates the board and that you can get for $49. The board should ship in December 2015, and Pocket C.H.I.P in May 2016….

The project looks exciting, but when you look at the details, it’s not quite as ground breaking as it may first seem. Shipping is $20, unless you live in the US ($5), so you’d buy a $29 board, which brings it very close to competitors. The internal flash, WiFi and Bluetooth are clear winners in this price range, but I assume few people will use composite output, so you’ll need to spend a few more bucks ($10 to $15) on adapters, and if you need these, you won’t get the board before May 2016… What do you think?

MINIX NEO Z64W (Intel Atom Z3735F) mini PC gets HDMI Audio in Ubuntu

May 8th, 2015 4 comments

We’ve been able to run Ubuntu on Intel Atom Z3735F mini PCs, as well as other Linux distributions, for a while, but with an important caveat: HDMI audio would not work, so instead you had to use an external USB sound card to get any audio. Luckily the problem seems solved, as Linuxium has now released a script (audio-wifi-minix-neo-z64-release.sh) and relevant files that will  patch your system to enable HDMI audio, and WiFI on MINIX NEO Z64W running Ubuntu.

Minix_NEO_Z64_Ubuntu_HDI_AudioIan Morrison (Liuxium) compiled a Linux kernel and the Wi-Fi driver, together with a modified DSDT (Differentiated System Description Table) table to fix an ACPI bug. He used John Pemberton’s Bay Trail Audio HDMI patch, as well as help from Paul Kendall for identifying the ACPI DSDT table bug, Bastien Nocera (hadess) for the wifi source code and DroidMote Server / Client for the wifi pointer.  A quick demo shows WiFi and HDMI audio working in Ubuntu.

It works on MINIX NEO Z64W, but I don’t see why it could not easily be adapted to any other Intel Atom Z3700 platform, you’d just need to patch the Linux kernel (3.16) and re-built it.
