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.

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

AM3352-SOM-1

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

LIME2 get better now with eMMC Flash A20-OLinuXino-LIME2-eMMC

A20-OLinuXino-LIME2-eMMC

A20-OLinuXino-LIME2-eMMC was developed first for customer of ours, but after we saw the result we decided that it’s good to add it in our web shop.

What difference make eMMC instead of NAND Flash?

eMMC behaves like SD-card so no need for special drivers, you write on it as you write on SD-CARD, it’s faster than NAND Flash, and it’s more reliable.

The eMMC Flash we use is industrial grade -40+90C SLC Flash from Micron. All other functionality remains same. Note thatA20-OLinuXino-LIME2-eMMC is still not 100% industrial temperature grade, the DDR3 and Ethernet PHY are in commercial temperature grade (0-90C for the DDR3 and 0-70C for Ethernet PHY), we have industrial grade DDR3 and can build A20-OLinuXino-LIME2-eMMC with such memories,so the next step to complete industrial grade temperature board is to find proper industrial grade Ethernet PHY chip.

Metal Frame Box for OLinuXino LIME with 7″ LCD is now in stock

LCD7-METAL-FRAME

The LCD 7″ Metal Frame Box is now in stock. We offer it only in black color.

Inside the frame there is space to assembly A10 or A20 OLinuXino LIME or LIME2:

LCD7-METAL-FRAME-2

All connectors of LIME are exposed on two sides on the frame box:

LCD7-METAL-FRAME-3

and from other side:

LCD7-METAL-FRAME-4

Four M4x8 screws hold together the two parts of the LCD frame, the same can be used to attach the frame to any flat surface.

The LCD assembly is easy to do but involves making frame of dual adhesive tape around the LCD to keep the glass off contact with the metal and to attach the touchscreen if necessary.

We offer this assembly as separate service if one do not want to make it himself. Here is the link for the assembly service – it’s orderable item in the web shop.

Please note that before you add LCD7-ASSEMBLY to your order you also have ordered these items: A10 or A20 OLinuXino LIME or LIME2, LCD-OLinuXino-7 or LCD-OLinuXino-7TS, LCD7-METAL-FRAME and CABLE-40-40-10CM otherwise we can’t do the assembly 🙂

The next logical step is to make Industrial panel. For this purpose we need LIME or LIME2 in industrial temperature grade.

A10/A20 qualify for industrial temperature grade, we also have all other components in this temperature range including the DDR3 memory, but two components preventing us to complete this job: NAND Flash and Ethernet PHY.

We work to solve this and in couple of months we may have in our web shop complete industrial panel solution with LCD, LIME etc in Industrial temperature grade -45+85C .

Metal Frame Box for LCD 7″ with LIME test

lcd1

Today we test the assembled LCD to see if it will work fine when mounted in the metal frame. Everything works fine and the panel is cute:

lcd2

It has good response and probably we will offer it complete assembled as it needs some skills after all to assembly precisely without breaking the glasses.

These will be run in production … and now time to 10″ metal frame design 🙂

The Metal Linux Computer – The first LCD industrial panel prototypes are ready

LCD9

What you see is our first sample of the metal frame for 7″ LCD with build-in A20-OLinuXino-LIME inside!

Our mechanical designer is getting better and better after the design of A20-OLinuXino-MICRO and A20-OLinuXino-LIME boxes. The box for MICRO was done after three attempts, the LIME box was done right from the second attempt, now the LCD box got perfect from the very first attempt!

The metal frame is done by three parts:

LCD1

Here above you see two parts, which connect together with single screw. Why this is necessary – LIME has connectors on both ends and it’s not possible to fit inside as the connectors go outside PCB borders

LCD2

this is the third part it’s bend to hold inside the touch panel and LCD:

LCD3

here is the frame with LCD and touchscreen in it:

LCD4

the LIME is attached to back panel with one screw on metal spacer, the left side connectors show outside a bit:

LCD5

then we attach the right side panel and screw them together:

LCD6

then the LCD part is snap to the other two and fixed with 4 screws:

LCD7

here is how it looks on the back side:

LCD8

the same four mount holes can be used the metal panel to be assembled to other surface there are provisional mount holes on the back side as well.

The whole construction is solid and reliable. The frame dimensions are: 190 x 102 mm the higher back side is 40 mm the lower side is 10 mm thick.

This whole frame have approx same size as MODEL-B box and have just few more bendings so the price I expect is to be same as on MODEL-B box i.e. about EUR 15.00

This means 7″ LCD panel with A20-OLinuXino with the metal frame will cost from EUR 81.00 and if TOUCH screen is add from EUR 89.00

A20-OLinuXino OSHW Linux computer is doing hard 24/7 work at Mining industry

20151203_134444

Noac Engineering is Bulgarian company which makes engineering automation, GPS fleet tracking, dispatching and monitoring systems in one very specific niche: the Mining industry.

There are working *huge* machines which cost *a lot of money*:

20151202_134424

and work in *extreme* conditions:

to optimizing their work is something which pays off very quickly!

Every hour of non working cost lot $$$ so they should run 24/7 in the best optimized way possible.

This is how the control room looks like:

20151206_173114

NOAC engineering has chosen to use OLinuXino for their systems running Debian.

They put OLinuXino in the vehicles, so they had to make metal robust box to protect the board from dust, vibrations, shocks etc. as these machines works in really hostile environments.

Needles to say the boards run 24/7 non-stop.
