3.3V Max Current

Post by TorRaf » Tue Sep 14, 2021 1:29 pm

Hello everybody,

I would like to use JP4 or JP6 on Kflop for my own interface board and I would like to use 3.3V power supply to drive some leds.

What is the max current @3.3V?

Thanks

Raf

Hi Raf,

KFLOP's 5V to 3.3V linear regulator is rated for 1.5A but should be kept under 100 degrees C. KFLOP itself takes much less than 500ma. KFLOP's 46 IO can add to this. You should be able to draw 300ma in all cases. Note USB power is limited to 500ma.
