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

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.

Allwinner released T2 SOC working -40+85C targeting automotive entertainment, it’s re-branded A20 with expanded operating temperature

T2

Allwinner released recently their T2 SOC targeting automotive entertainment panels.
Looking at the specs we saw that it suspiciously looks like A20.

t2-blk

This is not the first time Allwinner releases their old silicons under new names like A13-R8, A33-R16, R40-T3 etc.  I personally find this quite confusing.

We got some T2 samples and now assembly A20-OLinuXino-LIME, A20-OLinuXino-LIME2, A20-OLinuXino-MICRO and A20-SOM with them to test for hardware and software compatibility.
Once we are sure everything works OK will release T2-OLinuXino boards which will be with industrial temperature grade -40+85C for all components on the boards.

T2-abs

To this moment all our A20-XXX-IND boards has components for or exceeding -45+85C, but A20 SOC was specified -20+70C.

New Product in stock – mini PIR sensor PIR-SB312

pir

PIR-SB312 is small low power PIR sensor with digital output. Very easy to connect to Arduino and OLinuXino linux boards as can be powered from 2.7 to 12V.

It can sense objects from 3-5 meters and  due to it’s small size it’s easy to hide.

OLinuXino EEPROM content – one step ahead to single Linux image for all A20 boards

LCD10-METAL-FRAME-1

We are struggling for some time now to make one single image which to work on all A20 boards we have.

Our problem is that we have more than 20 different A20 boards/revisions/ etc and every time we have to add or improve something we have to generate and test enormous amount of images.

It’s not so easy task as this image should run on different boards with differnt memory speed etc settings, different ports connections etc.

To achieve one single image which to boot to all A20 boards our first step is to add some content in the EEPROM which all OLinuXino has.

The EEPROM now contain this info: Header, ID, Revision, Serial number, Configuration, Reserved area for future (MAC etc), Checkcum.

The new image we work on now (based on Armbian with mainline kernel) will automatically recognize the board from the EEPROM content and run.

What will happen if no valid EEPROM content is read (i.e. old boards), there is tool which to be used to write EEPROM content based on board revision.

We are going to release this image soon.

 

New Product in stock MOD-WIFI-AR9271 libre drivers and firmware WiFi dongle

MOD-WIFI-AR9271-2

AR9721 chipset is the only one on the market with completely open source linux drivers and firmware, this make it WiFi chipset of choice for people who respect their freedom.

We have MOD-WIFI-AR9721-ANT for quite some time and it’s very popular item, but the 200mm antenna make it not quite small. Now we add to our web shop the version without external antenna. It’s with 85 x 25 x 10 mm dimension and have same working distance as the external antenna version.

GNU/Linux Install fest in Plovdiv @ Olimex on December 10th

15241999_541171392758646_9152584434294422876_n

We will host for a first time GNU/Linux install fest.

If you have problem with some device or driver or don’t know how to tweak your Linux distribution, or just want to chat with other people who use Linux – come to us on December 10th, 11.00-14.30 o’clock and meet Linux experts who will participate this event and get free advice and help.

Where to find us? Here is Google Maps Olimex Ltd location. And here is picture of the map, the green dot is the Olimex Training building where the GNU/Linux install fest will take place:
