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

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.

LIME2 get better now with eMMC Flash 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.
