OLinuXino now can be produced in Industrial grade -45+85C


hynix micron
When we made OLinuXino design our intention was to make it working even in Industrial temperature ranges -45+85C.

Unfortunately we struggled to big problem, we couldn’t find DDR or DDR3 memory in Industrial temperature.

Most of the DDR memories are used for consumer products – phones, tablets, computers with 0-70C operating temperature.

At Electronica 2012 exhibition I went through all memory producers and only Micron confirmed they have industrial grade memory, then when I wanted to place order the European distributors asked me something like EUR 20 per chip and minimum order of 5K pcs which was insane if you want to build low cost product.

The situation with SD cards is similar, to find 4GB SLC Sd-card Class10 in industrial temperature and certification the prices were starting at EUR 30 for 1000 pcs, also not good option.

So for a while we put this industrial grade idea aside, but I was keep looking for industrial DDR memory sources.

Now I’m happy to tell you that we finally found DDR memories in industrial grade for both imx233 and Allwinner chips, so we now can manufacture these boards in industrial grade temperature:

  • iMX233-OLinuXino-NANO
  • iMX233-OLinuXino-MICRO
  • iMX233-OLinuXino-MAXI (we have both LAN9512-iJZX and DDR in industrial grade)
  • A13-OLinuXino-MICRO

as GL850 USB hub can’t be sourced in industrial grade these boards can’t be made industrial:
iMX233-OLinuXino-MINI, iMX233-OLinuXino-MINI-WIFI, A13-OLinuXino

We are now searching industrial grade Ethernet PHYs to may offer also these boards in industrial grade:

  • A10-OLinuXino-LIME
  • A20-OLinuXino-LIME
  • A20-OLinuXino-LIME2
  • A20-OLinuXino-MICRO

note that the price of the industrial versions will be a bit different due to the higher price of the industrial grade memories and Ethernet PHYs

for iMX233-OLinuXino-NANO and MICRO this is +EUR4.00 for iMX233-OLinuXino-MAXI and A13-OLinuXino-MICRO this is +EUR 5.00

also note that the industrial grade boards may be subject to MOQ of 50-100 pcs and will not be shipped from stock as standard products but you may need to wait 1-2 weeks to be assembled, tested and packed.

    Did you find any industrial SD cards? I bought some from Digikey that were $80ea for 1GB and 4/10 were DOA and another 2 failed. I’ve had much better success with cheap sandisk cars. This is in an outdoor metal enclosure that gets to around 40-60 deg C every day. (Australia + Dubai)

    As for Ethernet PHYs in industrial temp range – I personally am quite happy with using LAN8720 (for RMII) but there are MII versions aswell. They were made by SMSC which now belongs to Microchip

    Olimex do one single batch of 50 pcs for eache possible insdutrial board and I’m sure it will sold out in matter of days. If You are you sure as I’m do it only for the iMX233-NANO or MAXI and You’ll see😉 I personally will buy 2 industrial grade iMX233 boards for sure🙂

    Hi, I am glad that you can do that!
    What would be the price range for A20-OLinuXino-LIME2 at I-Temp?

    Hold on, isn’t A20 only working in the range of -20~80C based on its datasheet?
