– USB host
– UEXT connector
– JTAG connector
– console UART connector
– power supply +5V DC only
– reset button
– bootloader button
– status LED
– operating temperature -25+85C

With this board we decided to challenge how down we can cut the features to reach rock bottom pricing.
This board is still on design stage (actually we already completely routed it) and we are going to prototype it next week, so please do not ask when you can buy it. In matter of fact we are still not sure if it will work at all, as we removed the AXP209 power managment IC and decided to try if A13 will work just with DCDC fixed power supplies.
If we succeed the price of this A13-OLinuXino-MICRO will be around EUR 35 retail – and this for board with 1GHz Cortex-A8 processor and 256MB RAM.

When we discussed this with A10 developers they warned us that current Linux distribution for A10 is memory hungry and only Mali400 and VGPU when enabled need 100MB of RAM.
Well I’m pretty sure there are many applications where fancy 3D graphics are not necessary, or the Mali400/VGPU apetite may be lowered with some tweaking?
Considering what amount of software we already managed to run on iMX233 ARM9 with 64MB, I think A13-MICRO have his niches where will perform just fine!
Well Andorid 4.0 on 256MB may not work nice, but Linux should be OK.

So crossing fingers to see what will happend with the prototypes ­čÖé

For these who miss Ethernet we did some experimenting with USB-Ethernet adapters (starting from $3 on ebay) and A13 Linux Kernel supports them both USB 1.1 (based on QF9700) and USB 2.0 (based on AX88772)┬áversions the later is with several times faster transfer, so we probably offer these as USB accessories to A13-OLinuXino. And of course we will offer the WIFI alternative USB-RTL8188CU 150MBit as well. ┬áThe LCD7″module, Bluetooth USB dongles, 3G modem dongles and all accessoaries we preparing for A13-OLinuXino-WIFI will also work on A13-OLinuXino-MICRO.
