Which PD module do you use?

I think they're pretty much all unbranded and look similar, but now there are some with through hole outputs instead of pads to solder wire. If I didn't already have a stash I would probably get those and some right angle male headers.
Just watch out, 12v isn't a thing anymore in the new specs and might not work, best to build around 5v, 9v, 15v, or 20v.
Although usually if I just need 5v, I'm building around a D1 Mini ESP32 module that already has 5v built in.
I saw one in a YouTube build video that allows you to select output voltage / what it will negotiate using a pushbutton, the selection is indicated by the color of an LED (and hopefully persisted when powered down).
Edit: the one chx linked to above is precisely of this kind

A unique twist on this is a module that is programmed by a flashing light, for example a web page with a flashing image: https://hackaday.com/2021/04/21/easy-usb%E2%80%91c-power-for...

That _was_ my first choice, to be honest, but the device (and the chip itself) was unobtanium at the point I was looking at it.

I'm not the parent but I'm a fan of WeAct's modules. https://www.aliexpress.us/item/3256803150519042.html
Fairly cheap but easy to configure with the dip switches and the boards I've been sent have been high quality with good solder joints.
