Project power question

[dougal]

Okay, I have a battery-powered boost board with a female USB connector that I plug my Digispark into.


If I tap into the GND and 5V points on J2, can I safely power external components that require high current, like a 5V LED strip? Or do I really need to go more directly to the power output of the boost, before it goes through the DS?


What's the current limit if I do this?

500ma is the limit for power coming through the usb connection - because that is the limit of the schottky diode on the usb 5v line.

Thanks. I had hoped I could go higher, but at least now I know.

You can always remove the Schottky and bridge the spot with solder/a wire.
