Re: DRAWS Power


The onboard regulator is 3A at ~5.1V regulated at the Pi so there is no cable loss. The Pi is sensitive to under voltage.

I recommend using the 12V input.

Just to clarify for me, is the below correct?

DRAWS power connection @ 12v, will power both the DRAWS and the host Pi.

Yes, it feeds 5VDC to the Pi through the GPIO header.


Pi power connection @ 5v with a 2.1amp common Pi wallwart power supply (micro USB connector) will power both the host Pi and the DRAWS board.

The current is dependent on the model of Pi,  I typically run 2.5A or better to have some margin.
