Hello, what is the max current draw for a single GPIO pin? and the max in total? Thanks in advance.

There’s no FETs after gpio output so i think 50mA is the maximal/GPIO for sure u need enought power if u want want to use alot of them. Correct me if i’m wrong. http://dl.linux-sunxi.org/A83T/A83T_datasheet_Revision_1.1.pdf

Thanks for the answer. I have just another question for you, what is the output of a pin set to 1? 3.3v or 5v?
