A64-OLinuXino OSHW 64-bit ARM DIY Laptop idea update


A64-OLinuXino Laptop idea becomes with better shape, we managed to find supplier for the laptop plastic ABS body with 11.6″, 1366*768 LCD and keyboard where we can embed our A64-OLinuXino motherboard.


the body have power supply jack, 2x USB hosts, HDMI, SD card connector, headphones 3.5 mm jack, four speakers,camera, touchpad, power button



needless to mention this window button will become Tux :D

Software examples how to use BB-ADS1220 with OLIMEXINO-32U4 (Arduino Leonardo) and A20-OLinuXino-MICRO are available as reference.

According to ARM one of the Benefits of using Microcontrollers – no GPL

LOL I’ve not read something so ignorant for years :)
Hello guys! There is no restriction closed source software to run on Linux, it’s other thing if somebody will decide to use such software on this OS where everything is open.

Workshops at Olimex Training Building – 10th of January – Intel vs ARM, IoT and SMT Technology


2014 is almost gone, New Year is coming and we will start the year with three Workshops on January 10th.

Update your agenda: Starting from 14.00 o’clock on 10th of January in Olimex Training Building there will be three interesting workshops.

First Workshop will be about Intel vs ARM. Minnowboard MAX will be compared to OLinuXino and RK3188-SOM-EVB in terms of productivity, power consumption, Linux support, etc.

Second Workshop will present ESP8266 and RT5350 OSHW boards for IoT applications.

Third Workshop will be about SMT technology, type of components, how to design PCBs for SMT, what is solder paste, how to handle solder paste, how to design stencil for solder paste, how to print solder paste, reflow profiles, how to make profile and how to trouble shoot problems with SMT technology like printing, soldering etc. There will be practical demonstrations and will be shared know-how captured for the 23+ years of experience with electronics manufacturing which cost gold :)

Everyone is invited! This is free event.

We would love to hear your suggestions how to improve our Linux images


Please let us know your feed back https://www.olimex.com/forum/index.php?topic=3468.0 here or in our forum, let’s discuss what do you miss in our Linux images?

There already was discussion about Debian whishlist and we implemented almost all suggestions we hear in the latest images, now we want to hear your feedback on what do you think is best to add as initial scripting, enabled features etc.


Home Automation with Open Source Hardware ARM Linux board A20-OLinuXino and MOD-IRDA+



A20-OLinuXino is Open Source Hardware Linux computer. It consumes only 2W of energy but runs Debian Wheezy and basically with it you can do anything you can do with your desktop Linux server/machine.

What makes A20-OLinuXino more flexible than your computer is that it have lot of additional hardware resources which you don’t have on your desktop computer – like GPIO ports, I2C, SPI, UARTs etc.

With the low power of only 2W A20-OLinuXino can run 24/7 consuming less than 1% of what desktop x86 server would take as power consumption.

Another advantage is that with the build-in Lipo charger simple LiPo battery can run the OLinuXino for hours if the mains power supply fail, so no need for expensive server UPS.

This makes OLinuXino perfect choice for home automation board. You can easily attach web camera to USB port and make video surveillance server with backup power supply LiPo battery for instance.

Another nice feature is the UEXT connector which allow different modules easily to be connected to A20-OLinuxino.

Now we will show you what you can do with MOD-IRDA+ module which is IR receiver and transmitter. You can receive and transmit IR remote control commands and thus control other home appliances with IR remote controls like: TVs, Air conditions, Radios, Stereo amplifires, and any other home gadgets with IR remotes.

Combining this to the fact that with OLinuXino you have access to Internet and can drive GPIOs and so on with Web interface makes endless possibilities.

In the video below you can see how you can teach OLinuXino to do things when receive commands by IR remote control and how it can play back captured IR remote control commands:


Having all sources you can easily adapt these for your next Home Automation project.

A80 Octa core BigLittle SoC from Allwinner will be ready in 2014


Eva Wu from Allwinner marketing sent me the new logo for A80.

There is no much info about it yet, but it will be 8 core (4xCortex-A15 and 4xCortexA7) and Allwinner is working now on it. Probably it will have 8-16 GPU co-processors too, we hope these to be MALI but there are great chances these to be PowerVR like A31, Eva is silent on this.

This new 8-core SoC will position Allwinner again on top of Rockchip which work on Cortex-A12 and have now RK3188 which is the most productive Chinese SoC with 4-core Cortex-A9.

It’s great to see how these two companies penetrate in such fields where the Western companies dominated just few years ago and now are in the league where the big boys Samsung. Mediatek, Qualcomm etc are playing.

With 8-core the small linux computers will become desktop productivity. Let’s hope Allwinner will keep the SATA, Gigabit Ethernet, HDMI like in A20.
