ST Microelectronic released new interesting device it’s Cortex-A7 and Cortex-M4 in one package. This solves two problems – the connectivity and ample amount of DDR3 memory to run Linux on Cortex-A7 core and the additional co-processor with Cortex-M4 for Real Time tasks. On top of this it’s -40+125C operating temperature and with 10 years supply longevity warranty from ST.

The prices starts around USD 5, which is in same range as Allwinner/Rockchip.

Their top model STM32MP157C has 3D openGL ES2.0 and CAN. There will be finally properly documented Secure boot (we hope ūüôā¬† ):

From recent Twitter post I see than Bootlin already works on Linux support for STM32MP1.

Overall STM32MP1 looks like very promising SOC for Industrial grade Linux computer.

If you need more memory and micro SD card for your Arduino project -OLIMEXINO-2560 is with 256K Flash and SD card on board

OLIMEXINO-2560

OLIMEXINO-2560 is Arduino Mega2560 like board which keeps ports conversion but adds UEXT connector to connect our wide range of modules and sensors, works on 5V and 3.3V, and has on board micro SD card for file storage and logging.

Power supply uses DCDC convertor with input range 6-15VDC when OLIMEXINO-2560 works on 5V and 5-15VDC when OLIMEXINO-2560 works on 3.3V.

ESP32-DevKit-Lipo, ESP32-POE and ESP32-POE-ISO boards now have option with external antenna and all our ESP32 boards can be build in extended temperature range -40+105C for demanding applications

ESP32-POE-ISO

Our popular ESP32-DevKit-Lipo, ESP32-POE and ESP32-POE-ISO now has option with external antenna, so you can use them even with metal boxes. The external antenna extends their range by 20-30%.

We stock now ESP32 modules with 16MB of Flash, so if you run out of memory you can order any of our ESP32 boards with 16MB Flash module too.

Also we have ESP32 modules in extended temperature range -HT (high temperature) which works from -40C up to 105C for demanding applications.

Long Term OLinuXino supply – How it works?

We got question from customer of ours: “We are using your A20-OLinuXino in our product and I’ve heard that you are going to stop the production soon, is this true?”

Most of our customers are industrial machine producers and they need long term supply from their vendors. They do certification for their machines which cost a lot and they can’t afford to spend more money every year because the Linux module is not produced or changed. We already wrote several post on our blog that we supply our boards until there is demand for them and that we have long term supply agreement with Allwinner, but some people spread rumors and I have to write it and make it clear again: We will produce OLinuXino boards until there is demand. It’s even included in our GTC.

When back in 2014 I posted that we can supply OLinuXino forever¬†many people were skeptical (well yes it is exaggerated ūüôā ) and wrote back – do not believe Chinese suppliers, they will let you down etc. etc.

Allwinner though is keeping their promise and we can buy all Allwinner SOCs we use without problem. Our volumes allow us to meet their MOQ.

For instance A13 SOC is very old and Allwinner discontinued it several years ago, it’s even not listed on their web as product, but we still keep buying it and producing A13 boards for our customers. We have also many customers which used our boards as template to make their own variants and now we supply them with A13 SOCs so they keep manufacturing them. You will not find A13 for sale anywhere even in China, but we are expecting next lot of 90Kpcs A13 to come from Allwinner in few weeks. Yes we have to order such quantities as Allwinner need 3 month to produce the SOCs from the order to shipment.

Many customers ask can you guarantee 10-15-20 years of supply? I doubt anyone in industry can see so long ahead. Allwinner is young company, founded September 2007, i.e. less 12 years old. Who knows what they will do after 20 years? We see that Western companies with much more history change owners every year and no one knows what the new owner will decide to do, so no one can give you 10-20 years prediction or will simply intentionally or unintentionally mislead you.

For A13 and A20 this agreement works well last 7 years. Both we at Olimex and Allwinner has no reason stop production, which brings money to both of us. We got visit from Allwinner sales manager in March this year and he said that they never though they can sell A13 and A20 for so long time. Most of other SOCs they sell target consumer market where lifetime is 1-2 years top.

Linux and Open Source Hardware works well for them and prolong their sales.

A20-OLinuXino-LIME Revision H is now in stock. The OSHW Linux computer now support eMMC and can be produced with industrial grade temperature -40+85C

Ax0-OLinuXino-LIME-1.jpg

A20-OLinuXino-LIME now is at revision H. What is new?

  • We now support eMMC Flash
  • Ethernet PHY is changed from Realtek to Micrel/Microchip as latter can be purchased in both commercial and industrial grade
  • SPI Flash with hardware write protect is supported which allow board to boot from net.
  • Industrial version of LIME is available with T2 Allwinner with all components -40+85C operating temperature
  • EEPROM now contain unique MAC address , serial number and configuration info

We decided to drop the odd shape which was made specially to fit LIME in the Hammond plastic box, instead it range of Metal Boxes is available.

Latest image supports all new feature.

It’s confirmed T2 -40+85C ARM processor is pin to pin compatible with A20

T2

We assembled T2 on A20-OLinuXino-MICRO, A20-OLinuXino-LIME, A20-OLinuXino-LIME2 and A20-SOM and completed full functional tests, all peripherials on T2 works exactly same as A20 with same Linux images and setup, which confirms that T2 is just re-branded A20 with extended temperature range.

We wait now first volume order of T2 to arrive and we will add T2 industrial versions of ourA20-OLinuXino-MICRO,A20-OLinuXino-LIME,A20-OLinuXino-LIME2 and A20-SOM boards.

This will include T2 SOC, MT41K256M16HA-125IT:E DDR3 memories from Micron , Ethernet PHY all in industrial temperature range. For this purpose we moved in the newest revision of our boards from Realtek to Micrel/Microchip as latter has availability in both commercial and industrial temperature range, while Realtek parts are sold only in commercial 0-70C operating temperature. The price of the industrial version will be around EUR 10-15 more than commercial to cover the cost of the extended temperature parts.
