@ EriSan500 (Eric) - So I’ll just connect it to the 5V pin?

5V in/out pin

@ EriSan500 (Eric) -

What is the maximum current rating of FEZ Cobra?

Thank you so much for answering my questions

45

Do you mean the required current for the Cobra? From memory, up to 1A is a suggested power supply for this device, especiually when you’re using the TFT screen.

46

I read somewhere that the EMX Module can only be powered by 3.3V. Is that true?

47

Correct.

48

You can run the cobra off a regulated 5v safely when using a display though, I’ve done so for over a year without issue.

Do it at your own risk, though

I see the mix up. Are we talking about powering Cobra or EMX module?

51

With a display only, per first page of this thread. Dunno which is more recent

52

So if I only connect a regulated 5v to the 5v in/out pin, my EMX won’t power up?

53

@ Architect - oh, I’m talking about EMX. Sorry T__T

54

Ah sorry, my fault, saw the thread name and got confused.

55

@ Skewworks - Sorry. I just thought that since it is somehow connected to FEZ Cobra that I could ask about EMX here also. My bad
