Module: USB-C PD to [5v/3.3v/etc?)

[admalledd]

Using some trick such as this to simply get 5V 3A from USB-C, and include a simple 5 volt to 3.3 volt regulator such that both voltages are available at the same time: have a single module that can provide the simple common power rails most breadboard projects desire.

Other inspiration products such as https://www.sparkfun.com/products/15801 require programming or a full microcontroller, and other easy purchases use mini or micro USB instead.

I read up on USB-C PD myself and yeah, it's surprisingly complex. So I will probably work on a module which just uses the two resistors and a beefy regulator for 3.3 V first. In fact the serial module already has these resistors, just the regulator is pretty weak.

My biggest reason for a PD module was to have both the 3.3 and 5v at two or so amps, 10ish watts total. Many a time I have been testing things (with small servos before bigger just spinning free, LEDs, too many micros/chips...) and the more common 2.5w or 5w power supplies included with UART/Serial boards gets really annoying.

One option as a possibility is the 5v3a resistor layout, and then a "simple" switching regulator like MP2152GTF-33 to also get a 3.3v rail derived from the 5v, not looking for higher voltages: I understand PD can get quite messy if you want anything more, not trying to ask for that, and if someone does there are "better" off-breadboard adjustable supplies to turn to.
