Bumping this instead of making a new post.
What is the required power supply current for the 7I96? Can i just power this board from my computer USB 5V rail? With the data lines shorted it provides 1A before cutting out.
Yes, USB power is usually sufficient (even 250 mA is enough if you don't have
much external 5V load), _but_ you do lose isolation between the PC and
the control if you use USB power.
