EV3 Output Voltage

[oracid]

What is the voltage of the EV3 output port ? In this video, I show you the answer.

I was wrong ! It is always better to measure.

In this page, you have all the technical links about EV3, https://education.lego.com/en-us/support/mindstorms-ev3/developer-kits

Hi,

Thanks for the demo and the link :)

Grady J. Koch has also tested EV3 voltage output. He reports that pin 1 output is linear across the native power range. Using the "unregulated motor power setting" percentages, he found 10-100% moves from 1V to 8V, with a 38% setting spitting out an even 3V.

So, if you want to know the voltage at different unregulated power settings than 100% and you don't have a voltage break out board set up, then you can see the plot on his site:
