This is not a version of the board, which was sent. Here is the board that came: A64-DB-2T-Rev B 02/25/2016 or 201 A64DB110-02 A64-DB-B1.1 2G

The fact that the sticker on your board have different date doesn't mean the above schematic is not relevant, because the date of the sticker probably means the manufacturing batch date, the Rev.B is still the same, otherwise it would have been Rev.C or something like that.

I agree. But the board has differences such as the power source selection - battery or power supply unit, since 2 gigabyte version is the ability to replace something else (immediately striking a smaller amount ceramic capacitors chip memory power filter on the bottom board, apparently because of lower heated more than the chips on top). I do not like that the heated areas that should not have this temperature, it is not known how to behave like voltage regulators for usb hub, upon application of additional power (in fact it will be the closure of their output to the input, for each usb connector a stabilizer), that will be used to start board. somewhere in the forum saw the promise of a schematic diagram, but something the result has not yet appeared.

I doubt : If they have made some changes on the schematic, then they would have rename version Rev.C.

I have a 2GB board too, so this means that the Pine64 team still put Rev.B stickers on Rev.C boards ... not professional ... :-(

You can see the 1GB board isnt just a 2GB board with missing ram on the bottom. And we know the jumper affects where power is provided from to the USB. Best group of pics so far. http://linux-sunxi.org/Pine64 The need for the 2GB schematic isnt that big for me mainly just a curiosity.

Weird design strategy ... Being an engineer myself, I would have common design for both version with single PCB version ...
