[Arm-netbook] Open source Allwinner R40 circuit diagrams

[jim]

Hi, 

I'm out on a limb with Allwinner R40 circuit diagram. 

I want to make open source KiCAD Linux board(s). 

This time I got more funding to finish the project 
compared to the A10/A20 version tried when EOMA was
being prototyped :)

I only find the BPi version so far. 

Anyone know of any others open sourced boards that I could learn from? 

Regards, 

Joe
