If you need second (or third) Fast Gigabit Ethernet interface on your embedded Linux computer or desktop our Open Source Hardware OSHW USB-Gigabit adapter is what you need!


Many of our customers ask if we can design board with two or three Gigabit Ethernet interfaces. The Allwinner chips we use for OLinuXino are general purpose not communication chips so they usually have single Ethernet. The Sitara SOC we use AM335X advertise to have more than one Ethernet interface but it’s marketing as these are virtual interface i.e. share transfer speed.

USB-Gigabit allow you to add 10/100/1000Mbit interface to any of your computers which has USB host. It supports USB 1.1, USB 2.0 and USB 3.0 interfaces and speed depend on your USB port speed.

Our tests with A20 OLinuXino boards with USB 2.0 host interface show 319Mbit of Upload and 295Mbit of Download speed i.e. x3 times more than our other USB-Ethernet-AX88772B interface.

New Product in stock: A10-OLinuXino-LIME-UEXT adapter


A10-OLinuXino-LIME-UEXT is adapter board with Male connector on 0.05″ which can connect to A10-OLinuXino-LIME GPIOs with  0.05″ step ribbon CABLE-40-40-10CM and allow LIME GPIOs to be used with BREADBOARD-1, or with A13-LCD43TS, A13-LCD7TS or A13-LCD10TS.

For the moment A20-LCD15.6 is not supported as LVDS signals got noisy when pass through A10-OLinuXino-LIME-UEXT but we are looking for solution.

UEXT signals can be used only when connected to GPIO1. On the other connectors UEXT signals will be not present.

New Product in stock: MOD-WIFI-R5370-ANT 802.11b/g/n 150Mb adapter for OLinuXino with external antenna


MOD-WIFI-R5370-ANT is based on Ralink 5370 chipset and works with PSP, Linux, Windows, MACOS etc.

The advantage vs MOD-WIFI-R5370 is that it have bigger range due to the external antenna. The disadvantage is that it is bigger and takes more space.

MOD-WIFI-R5370-ANT is supported in the Debian images we distribute for OLinuXino

New Product in stock: MOD-WIFI-R5370 802.11b/g/n 150Mb adapter for OLinuXino


MOD-WIFI-R5370 is based on Ralink 5370 chipset and works with PSP, Linux, Windows, MACOS etc.

The advantage vs MOD-WIFI-RTL8188CU is that it have smaller dimensions and it’s more compact when plug to OLinuXino.

As disadvantage we found it to have less wireless range than MOD-WIFI-RTL8188CU

MOD-WIFI-R5370 is supported in the Debian images we distribute for OLinuXino

Friday Free Board Quiz Issue #48 prize is USB-Ethernet adapter


USB-ETHERNET adapter allow you to connect your computer to Ethernet via USB port. It works with OLinuXino and should work with most PC computers too.

You have chance to win this board!

Today at 17.00 o’clock our local Bulgarian time (GMT+3) we will post on Twitter our questions.

You have one hour to reply to our tweet with the correct answer.

At 18.00 o’clock we will count the correct answers and ask random.org to generate random number in range then announce the winner and ship the board by airmail in Monday.

And there is more…

as there are many people in different time zones which could not participate in Friday quiz at 17.00 o’clock, today we will give away one more USB-Ethernet board without Quiz to random person who used the buttons below to re-tweet, share on Facebook or in G+ during the weekend, the winner will be pickup next Monday.

New Cheaper Power supply adapters 5V and 12V in stock


We offer two power supply adapters for OLinuXino: SY0612E 12V 0.5A and SY0605E 5V 1A both are produced in Romania by Sunny Computer Technology Europe SRO, which is factory established by Sunny Computer Technology China.

These adapter are with good quality, come with all certificates and meet all safety standards, but they are bit expensive.

We found cheaper adapters manufactured in China which are at half price than these manufactured in EU.

Here we disassembly both to see the difference:

1. PCBs on both adapters are made by cheap FR2 material;


2. Electronic components, capacitors, transformers, semiconductors in both adapters are with good quality; We have been diassembling ultra cheap adapters which sells for $1 with free shipping on ebay and they are really bad quality and will break after few plugs on the mains, there are no distance inside between high/low voltage parts and it’s quite dangerous to use such adapters at all, but this one is not such case. The Chinese adapter have even bigger air distance between the high and low voltage part than the EU made, but I think this comes from the fact that EU adapter have protective coating and is allowed to have narrow distance.

3. EU adapter uses wires with bigger diameter, Chinese is made with thinner cables which for sure will withstand the small currents which are used, but will fail sooner if somebody pull or twist the cable.


4. EU adapter PCB is with protective coating on the solder side (which make surface glossy) and which will protect the PCB when working in humidy enviroment, the Chinese adapter have no protective coating.


5. EU adapter the power connector is with springs inside which always guarantee good contact with the power jack on the board, Chinese connector is simple with no springs inside.


6. EU adapter have all certificates and safety standards tests, Chinese adapter may pass these, but they didn’t bother to spend money on certification and didn’t mark the adapters (actually they would mark them if we asked 🙂 but this is not the point, you can’t be sure if there is certification on goods you buy from China as they will mark it with anything you want.

Generally in our opinion both adapters will work well, the EU adapter of course is with better quality but at double price. If you want to use the adapter just in your lab or at home and you are at low budged the Chinese adapter will do the same job for you.

If you want use the adapter in project where you want more reliability or the device will be subject to high/low temperatures and humidity you should choose the EU adapter.
