Heya,

I've purchased both NodeMCU boards from ebay, both have ESP soldered.
Ver 0.9 is -12, ver 1.0 is -12E.

And both have the "auto program circuit" as described above?
Do you have a link? Or a picture?
I tried to communicate with some vendors, but they do not hand over any circuits, or schematics before purchse :-(

Just a side note . I was looking at the FT232R chip and RL. I see their maximum current out is 75 mA so this thing drawing up to 250 mA and the FTDI cable alone may give some problems that are hidden in there.
