New Sitara AM3352-SOM-IND with industrial grade components work from -40C up to +85C


Our popular AM3352-SOM module now is available in industrial temperature grade -40+85C under name AM3352-SOM-IND.

MT41K256M16HA-125IT:E memory used is with -40+95C operating temperature.

AM3352BZCZA100 processor used from Texas Instruments  is with -40+105C operating temperature.

AM3352-SOM-IND module can be evaluated with AM3352-SOM-EVB.

Debian Linux distribution is officially distributed, but recent patch add support for AM3352-SOM in Beaglebone kernel

World smallest System-On-Module with A20M released, dual instruction set x86 and ARM v7, can run any code in and OS!


What you see above is our first prototype of A20-SOM-NANO with only 30×15 mm this is the smallest A20 System On Module running Linux, Windows, Android and DR-DOS 3.3!

It’s based on the newly released A20M processor which is dual architecture and can run with ARM and x86 instruction set. This makes possible to use all existing software which runs on ARM and x86 platforms, even the old DOS programs can run on Linux and Window bash command prompt without any modification.

The best of all is that A20M is pin to pin compatible with A20 but with balls on 0.4 mm step and dimensions only 7×7 mm.

Allwinner specially designed this processor for our new module so you will not be able to buy it through their distribution channels.

These modules are assembling now and will be in stock next week!


A31-SOM update


About year ago we posted on this blog about our work on A31 SOM module, a lot of time passed away so we would like to make clear statement about it’s status.

A31 SOM hardware was complete long time ago, but we found lot of bugs in A31 during the software development. Lot of things do not work as expected and the chip have overall poor performance. The video is with PowerVR which means there will be no Linux acceleration forever. All you will got running on it with hardware acceleration is Kernel 3.4 with Android. Memory do not work reliable above 200Mhz clock which is terrible performance. While we have hesitated if we have to put more effort on this chip we got notice from Allwinner that they discontinue A31 and A31s production which ended our hesitation.

A31 has very short life, Tom Cubie shared on IRC before while that Allwinner internally hate this chip with all it’s bugs too 🙂 so I guess Allwinner also got relieve to get rid of it.

Leasons learned, we move forward 🙂

RK3188-SOM, RK3188-SOM-4GB and RK3188-SOM-EVB are in stock now!


RK3188-SOM and RK3188-SOM-4GB system on modules are now in stock, these modules have same size as A20-SOM 81.28 x 55.88 mm and use same 0.05″ connectors, well they are not exchangeable though.

RK3188 is quad core, Cortex-A9 running at 1.6GHz. What does this means? Comparing to A20 you can expect everything to run about 10 times faster.

As power requirements, it takes more power than A20 obviously you pay for the performance and the higher clock rates.

For these who want to make their own board we made RK3188-SOM-EVB template with:

  • HDMI
  • 100Mb Ethernet
  • x4 USB hosts
  • RTC clock and backup battery
  • +6-16VDC power supply
  • LCD connector where you can connect LCD-OLinuXino-XX LCDs
  • 2x 40 pin 0.1″ step GPIO connectors

RK3188-SOM starts from EUR 35 for 1000 pcs and it’s probably least expensive quad core Cortex-A9 1.6Ghz module on the market, the RK3188-SOM-4GB starts from EUR 40 / 1000 pcs.

The evaluation board RK3188-SOM-EVB cost EUR 70

The most anticipated AM3352-SOM-EVB boards are now in stock


The development of this board was epic, mostly because of the messed up Linux SDK for Sitara and the absence of any real help neither from TI neither from Beagle Bone community, which do not care for anything but BB 🙂 Also the comprehensive and confusing TI documentation.

Finally we have got working clean Linux with cut off vendor locked crap (we don’t say this is done perfectly, probably there are people who can do this better and faster than us), but we wanted to do it the hard way and to learn something meanwhile.

What we have on AM3352-SOM-EVB is:

  • AM3352 Sitara running on 1Ghz
  • 512MB of DDR3 RAM
  • power management without using expensive TI PMU parts
  • VGA output
  • Dual Ethernet 100Mbit
  • 4 USB hosts with power management
  • CAN with driver
  • LCD connector where you can connect our LCD-OLinuXino with 4.3″ 7″ and 10″, 15.6″ LCD will not work as it require LVDS which Sitara do not have
  • UART console
  • JTAG
  • 2x UEXT connectors with SPI, I2C and UARTs
  • GPIO connector with Analog Inputs, PWMs, GPIOs etc.

all this for EUR 60

For these who want to build their own Sitara boards the AM3352-SOM modules start from EUR 25.90 for 1000 pcs and cost only EUR 27.75 for 100 pcs.

Industrial version of AM3352-SOM can be build on request, it will cost EUR 5.00 more and the minimum order is 100 pcs.

Our first A31-SOM – Quad Core ARM Cortex-A7 System on Module prototypes work fine!


We just assembled our first A31-SOM module prototypes.


They have these features:

  • A31 Quad Core Cortex-A7 @ 1Ghz, Octa core Power VR SGX544MP2 GPU, designed for power efficiency, 1MB L2 Cache, 32K I-Cache, 32K D-Cache, FPU, NEON SIMD
  • 2GB DDR3 RAM with 64 bit data bus for fast access
  • optional 8GB NAND Flash
  • Power Management Unit AXP221
  • LiPo battery charger and step up for USB 5V supply
  • micro SD card
  • 3 buttons
  • UART0 console connector
  • all GPIOs and pins on x6 40 pin 0.05″ connectors
  • RTC, Timer, HS-Timer
  • 16-Ch DMA
  • x2 USB Low/Full/High speed Hosts
  • 4SPI, 5 TWI/I2C
  • x6 UARTS
  • x2 PCM
  • x2 I2S
  • ITU601 / MIPI CSI
  • HDMI 1.4
  • x2-CH LVDS
  • x2-CH RGB LCD
  • IR
  • GMAC
  • Audio codec
  • 4K x 2K video playback

We need some weeks to test them before run production, so these modules will be in stock end of September earliest. A31-SOM price will start from EUR 44 for 1000 pcs, A31-SOM-8GB price will start from EUR 54 for 1000 pcs order.

We also designed A31-SOM-EVB for A31-SOM modules, which is OSHW mother board reference design and have these features:

  • Gigabit Ethernet
  • USB-OTG connector
  • 2x USB Host connectors
  • UEXT1 and UEXT2 connectors
  • SD-MMC connector
  • LCD connector compatible with our LCD displays – 4.3″, 7″, 10″, 15.6″, 15.6″HD
  • Audio output 3.5 mm jack
  • Audio input 3.5mm jack
  • 2Mpix @30 fps Camera on board
  • HDMI connector
  • LiPo battery connector
  • RTC CR2032 Li battery backup connector
  • GPIOs on prototype friendly 0.1″ connectors
  • Power jack 6-16VDC

A31-SOM-EVB evaluation board with A31-SOM-8GB on it will cost EUR 97 in single quantity.

Although A31 is only Cortex-A7 you can see here  interesting comparison between RK3188 and A31 video performance.

A31 have better picture and faster video playback than RK3188 which do not have native HDMI but used LCD-> HDMI converter.

A31 supports up to 4K video playback and have 64 bit RAM data bus.

Android 4.2.2 runs fine on A31-SOM and all features are supported.

Regarding the Linux Support, there is more than year and half efforts from Maxime Ripard @ Free Electrons to bring A31 to mainline, but still some major drivers are missing though like Video, Audio and NAND.

Linux-Sunxi tree miss A31 so far, probably because there is no good development hardware for A31 platform – all devices available are either tablets either Android dongles with no Ethernet, GPIOs etc. exposed. Now when this changes perhaps some Linux-Sunxi developers may be interested 😉 we built 5 prototypes and use only 2 of them so we have 3 to send to interested developers.

With the current Linux support A31 is still good for headless Linux server with the Quad cores, 2GB RAM and Gigabit Ethernet.

Linux kernel from Allwinner SDK is also option but it will be step back from mainline. Anyway with the missing Linux-Sunxi support this is also an option for these who need Linux instead of Android.

A31-SOM will be good platform for digital signage, video processing, IP cameras, or VoIP etc.


New A13-SOM-LTE design on GitHub



What you see on the picture above is A13-SOM-LTE shield which enables 100 Mbit 4G Internet access to A13-SOM.

The LTE shield is specially designed for 4G module from partner we work with. This is the first prototype and some tests should be completed but it’s matter of weeks or months these modules to be released. We still have no price on the 4G module as these are very new but we are assured to have them on the very low cost, so with A13-SOM to enable wearable cloud technology.

100Mbit is enough to listen music, watch videos, log large amounts of data to cloud storage.


A13-SOM-LTE shield is OSHW, the schematic and CAD files are on GitHub.
