I learned about these neat USB boards. I think I will use one in 9V mode for the Atari 7800 as an alternative means of powering it. It might fit in one of the existing cutouts.

Seems pretty neat, got any more info?
Just search aliexpress for “pd trigger” and they’re pretty common.
You can also get usb c to DC barrel jack cables, that come preconfigured for various voltages.
I was curious myself so I looked up the data sheet fro the chip… I need this board in my life

I don’t understand the reference between VBUS and VDD. Is anyone willing to explain how the risk of putting direct PSU voltage into the output device is avoided?
