Control usb pd trigger with Arduino

Hey there,
so I recently found this usb pd power trigger and I wonder if I can control this trigger instead with the button on the board with an Arduino?

Thanks! :slight_smile:

Your link is not usable, it is zoomed in way to much and it will not un zoom. The top and bottom 1/3 of the screen has banners on. To answer your question I would guess you can, simply replace the button with a relay, I cannot get a clue as to what the power trigger is.

For your comfort:

The proper webpage.

This image:

shows that the switch grounds one pin of the 32F030F4P6 microcontroller which would have an internal pull-up. Given that you have connected the grounds, you could use a Schottky diode with cathode to Arduino and anode to the switch connection to pull the pin down and emulate the button - for whatever reason you believe you need to.
