This is great. Even just soldering on a barrel jack and shrink tubing the whole thing would be a massive improvement.
All the old Power Supplies from the 90s and earlier made power really inefficiently and their failure modes can be… bad
Putting a GOOD USB-C charger onto these old systems is an elegant solution!
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?
