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

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!

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 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:
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 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:
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.
