oracid Posted November 14, 2018 (edited) 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 Edited November 14, 2018 by oracid Share this post Link to post Share on other sites

Bline Posted January 13, 2020 (edited) 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: Page: http://hightechlego.com/EV3 Voltage Source/EV3 Voltage Source.php Image: http://hightechlego.com/EV3 Voltage Source/EV3 voltage source graph.png Edited January 13, 2020 by Bline Share this post Link to post Share on other sites
