A20-OLINUXINO-MICRO now available also in Industrial temperature grade -45+85C

A20-OLINUXINO-MICRO-EMMC-3

We are selling for some time already A20-OLinuXino-MICRO Rev.J where few things were improved:

  1. We changed the LAN PHY from Realtek to Microchip as latter is more reliable supplier for both commercial and industrial temperature components, we searched desperately Realtek PHY in industrial temperature grade but without success.
  2. We extended the input working voltage from 6-16VDC to 8-24VDC
  3. We changed the NAND Flash to eMMC (but old NAND style flash is still possible to assembly)

The Ethernet PHY change requires new patches on the Uboot and Linux images which are already uploaded.

A20-OLinuXino-LIME2 now with PCB revision G

a20-olinuxino-lime2

A20-OLinuXino-LIME2 now is assembling on same PCB Revision G as A20-OLinuXino-LIME2-eMMC.

What are the improvement:

  • Ethernet PHY is changed to RTL8211E replacing the obsolete RTL8211CL no need for kernel patches;
  • we drop the odd shape which was necessary to fit LIME2 in the plastic box as we now have range of metal boxes;
  • the four mount holes now have grounding for better contact with chassis;

Meantime we silently work on further improvement for next revision (to be released March 2017):

  • adding SPI boot Flash;
  • replacing RTL8211E to industrial grade PHY, so the board can be produced completely in -40+85C operating temperature;

 

A20-CAN – new OSHW board designed with KiCAD adds CAN networking to A20-OLinuXino and A20-SOM

A20-CAN

Want to sniff your car’s CAN bus or to drive Industrial machines with CAN networking bus?

Allwinner A20 SOCs have CAN but almost no one use it. If I remember correctly it was not even included in the Allwinner documentation just two pins had CAN on their names, so many people doubt if there is or not CAN.

Fortunately some people investigated further and add proper CAN support for A20 Linux, so we decided to make small driver board which to allow A20-OLinuXino and A20-SOM to have CAN. What does this means? Now you can use A20-OLinuXino to talk to other devices with CAN like industrial equipment, automotive CAN bus etc etc.

Current Linux image we have is without CAN support, but we put instructions on our WiKi how to build one with Linux-Sunxi 3.4 Kernel and with Mainline kernel: https://www.olimex.com/wiki/A20-CAN

What you see above on the picture is our first prototype of A20-CAN it works well although we use 5V CAN driver and A20 is 3.3V device. We successfully connected AM3352-SOM-EVB to A20-OLinuXino-LIME with A20-CAN driver and exchanged some messages at the highest speed 1Mbit and it works fine.

All CAD files, Gerbers, BOM are in this Github account: https://github.com/OLIMEX/A20-CAN . The board is done with KiCAD.

The PCBs are now in production and in 2 weeks A20-CAN will be orderable on our web page . While the PCBs are made we will work to add the CAN in our official images, so you do not have to bother with Kernels configurations and re-compiling.

REDS.box – Home cloud server based on A20-OLinuXino-LIME on Kickstarter

REDS.box is new Kickstarter project which use A20-OLinuXino-LIME to create your own home server to keep your files safe and available on the net.

People who use a cloud app these days have to store their data on servers of the companies that provide the app. Without knowing what will happen to your data and who else has access to it, you are asked to trust those companies – which means you are losing control over your data and privacy!

With REDS.box you know exactly where your files are – on your own server where only you have the access rights.

 

Allwinner did it again – New quad core powerful chip pin to pin compatible with A10 and A20!

A20-OLinuXino-LIME2-1

A10 was one of most successful chips made by Allwinner, for couple of years it was top seller in tablets and other devices, A10 also was selected for our EUR 30 low cost Linux board the LIME.

Then Cortex-A8 single core become obsolete, then Allwinner released A20 – Dual Core more powerful and power efficient Cortex-A7 processor with pin to pin backward compatibility to A10.

This was incredible wise move for Allwinner as people could just re-use their old PCB designs without spending time to change PCBs.

A10/A20 had one nice feature – they have LCD, HDMI, SATA, Ethernet, in A20 Allwinner even add Gigabit Ethernet on top of the normal 100M Ethernet. All other new devices they release have either LCD either HDMI but not both and we miss SATA interface in all new Quad core devices they released.

Now they did it again – we got information from Allwinner that they are about to release Quad core more powerful processor which to be pin to pin compatible with A10/A20 we still don’t know the name, maybe A40 ? 🙂

Anyway this is very clever move as all existing designs which people have can be re-used. This means more modern SoC with more power but without forcing you to re-design your boards.

So expect Quad core LIME soon and I guess at same price range like other LIMEs!
