USB-C PD as modern standard

[probably-Erwins-Cat]

USB-C PD chargers have long surpassed power bricks in terms of quality, power, voltage compatibility, and safety features. It would make sense to switch over to USB-C PD.
There are now many ICs that make USB-C PD child's play, e.g. HUSB238, HUSB238, CH224K etc.

Upside: E-TKT would benefit from safety features and availability of USB-C PD chargers.

Downside: The current number of capacitor density will cause an in-rush current spike at startup, which will likely trigger USB-C overcurrent protection. This "downside" can easily be remedied in many ways, adding more safety to the PCB anyway.

Thats a good idea, much more elegant and compatible.

Do you know if there a sweet spot on these USB-C PD power supplies that would grant the peak power needed when embossing? Just to compare cost/benefit...

I see you are working on that on your branch, curious to see the practical tests.

I will test the prototype board with 12V USB PD. The max rating (without PPS) is 3A @ 12V, so I expect it to be sufficient when the servo stalls.
