A64 OLinuXino OSHW Linux Laptop idea becomes more real :)


Few weeks ago I blogged about the idea to make OSHW Laptop based on Allwinner A64 64-bit SoC.

Today we received the first samples of the laptop plastic body.

The quality of the plastic parts is very good!

As you can see we have already sourced the plastic body, the battery, LCD display, keyboard, touchpad, speakers, camera, microphone and all fittings.

What’s left is to design the motherboard to fit inside the plastic body.

The feeling of building your very own laptop by yourself is incredible.

Every one can go to the shop and buy laptop, but to build one with your hands, and to know every component inside is different experience.

We start seriously thinking to make Do-It-Yourself kit version where you get all components and instructions and can build your laptop.

Why not choose different boards with different SOCs and configurations which you put up to your choice.

These who come to the Help Day this Saturday will be able to touch for first kits, we have one in White and one in Black.

Crossing fingers to may complete the mother boards to show at FOSDEM in January :)

Is it time for Open Source Hardware x86 OLinuXino?


We have been so focused on ARM that somehow we have missed the Intel latest development.

Yesterday browsing the net I saw $100 tablet with X5-Z8300 and check the datasheet. It looks good!

Quad Core 1.84Ghz 64-bit data bus “Cherry Trial” Atom with support for up to 4GB DDR Ram, USB 3.0 (!) we guess working as on A80 USB3 is one of the broken peripherials. PICe, MIPI camera, display etc.

All this come in handy BGA 17×17 mm 0.65 package not quite different than Allwinner A64 part.

And of course it comes with first class documentation you can see product page and documentation.

Intel write recommended price for tray $20 in their site, but brief check shows that it could be sourced from China at less than $15. Much better deal than the obsolete iMX6 quad core SoC for instance! Still x3 times more expensive than Allwinner A64 but probably x10 times more powerful.


  • first class SOC vendor 14 nm process;
  • well documented;
  • nice features;
  • removes the cumbersome ARM obsolete Android Linux Kernels problems;
  • you can work with the latest vanilla Linux Kernel;
  • we guess Graphics and Video drivers are also mainlined;
  • can run Linux, Windows, Android whatever you want;
  • can be build to work with standard  64bit computer memory modules, so you can put whatever amount of RAM you want up to 4GB;


  • probably more power hungry than ARM, but maybe not, the tablet I was looking at was with 4000mAh battery



A33-OLinuXino OSHW Quad Core Linux SBC prototypes ready for test


We just assembled our A33-OLinuXino prototypes, these have PMU and should not overheat so badly as H3.


The advantage to have PMU is also that it have LiPo charger and can run from LiPo battery.

The features are:

  • A33 Quad core Cortex-A7 SoC
  • AXP223 PMU
  • 1/2GB RAM
  • optional 4GB NAND Flash
  • Audion Input
  • Audio Output
  • CSI/DSI connector
  • 40 pin LCD connector for LCD-OLinuXino-XX LCD modules
  • GPIO 40 pin connector

Both H3 and A33 support dual CS DDR memories, this means they can work with the new 8Gb DDR3 ram chips which have two CS lines and H3-OLinuXino and A33-OLinuXino could have 1GB or 2GB RAM as option.

A33 have no Ethernet and HDMI, would be good for handheld video/audio processing devices.

The next revision of H3 and A33 OLinuXino will have eMMC option too.


EDIT: 18.00 o’clock update A33-OLinuXino is booting and working fine. As we expected although with same Quad Core Cortex-A7 it do not overheats at all compared to H3. Something is really broken in the H3 Linux clock/power configuration!!!

A64-OLinuXino update


We just got some more information from Allwinner for A64 and the good news is that it have Gigabit Ethernet interface!

So beside the WiFi + BT 4.0 A64-OLinuXino will have also native Gigabit Ethernet interface :)

OLinuXino roadmap 2015 :)


Many people ask us about what we do with Open Source Hardware OLinuXino project. Indeed we didn’t blog about OLinuXino boards often, but this doesn’t mean we do not have fun and working on them.

So let’s make brief update:

RT5350F – the DIN rail version is already complete and wait for assembly, the issue is trivial the plastic box, it will take us most of the time to complete.

Other OpenWRT boards:

We completed and now prototype MT7620N @580Mhz with some more RAM – 64MB and two WIFI bands 2.4G + 5G and 5 10/100Mb Ethernet and prepare board with MT7620A @580Mhz and little bit more RAM 256MB, x2 Gigabit and x4 10/100Mb Ethernets.

When these will be released – we don’t know, RT5350F software took us about year to get NDA info about WiFi tunning, we don’t know what it will be with MT7620, so do not hold your breath :)


A33-OLinuXino (Quad Cortex-A7) now is complete and on prototype stage, still had no time to check if Linux-Sunxi community have Linux for A33 and at what stage it is.

Now we route H3-OLinuXino (with Quad Cortex-A7 and which have Ethernet and HDMI) and A64-OLinuXino (with Quad Cortex-A53, HDMI, Camera, MIPI/LVDS/RGB, Gigabit Ethernet).

Why we stopped to blog or announce so often the new boards we working on?

Because when we blog that we start working on new OLinuXino board many people start to make commercial plans with them and how they will obtain OSHW designs for free for their commercial idea/project. Sure this have nothing wrong, if some of them didn’t became too impatient, annoying and noisy if the release time do not match their expectations. They forget that we do this for fun and we do not have any firm release dates, so they try any forms of social engineering posting challenging or abusive messages thinking they would influence us somehow this way, well soon or later they realize they can’t but anyway this is annoying for us as we want to work in rest calm environment and enjoy what we do.

We learn while we do this stuff, AM3352 software support took us year and half, we couldn’t find vital info for RT5350F for more than year, I have no idea when MT7620, A33, H3 or A64 will have proper Linux support, so please do not hold your breath, these boards will be released when they are ready, if you are capable to help with Linux on these please let me know, we can send you preliminary prototypes, so we can work together to speed up the release.

New Open Source Hardware KiCAD project board in stock: MOD-OLED-128×64


MOD-OLED-128×64 is low cost, low power, high contrast LCD display with UEXT connector which allow to be used with any of our OLinuXino and Arduino boards.

The LCD panel control is done via I2C thus only 4 wires are necessary Vcc 3.3V, GND, SCL and SDA.

The power supply required is only 1 uA in sleep mode, 200 uA in operating mode and 7mA in display ON mode.

View area is 21 x 11 mm.

MOD-OLED-128×64 can be used on Breadboard too. For this purpose 4 pin header is provided which could be soldered on the back of the board.




KiCAD files are on GitHub, Python code to work with any of our OLinuXino Linux board is provided, also code for Arduino.
