Where to buy? #16

I know that here is not a place to post that kind of question but I spent couple of hours and could not find a place to order the PD_Micro. The only place is at https://www.crowdsupply.com/ryan-ma/pd-micro#products and it shows No longer available.

Where should I buy it today in 2023? Thanks

Hi, I don't want to discourage people from buying or making products by Ryan Ma. But Ryan has seemed to be offline for a while now. If you are interested, I am making an upgrade board call PicoPD that might be a good substitute

@baonguyen21 board looks promising, but I'm looking for a combo output system to replace my N64 power supply. does Pico output multiple voltages?

if there is a board that can deliver 3v, 5v, 12v - you would cover most if not all hobby projects and retro projects.

You can request different voltage but not multiple voltage. At any given time, you will have 3.3V coming out of the on board LDO, but then one extra from the power line from USB PD. I don't own an N64 myself but my Google search is showing 3.3V @ 2.5A and 12V at less than 1A. That is pretty high amperage for 3.3V rail. My suggestion would be using a trigger board to request 12V, then use 3A buck to step down to 3.3V.

Some wall plugs dont provide 12V rail, but support 12V in PPS mode. So for future proof, you can consider a PPS trigger like this one: https://www.elecrow.com/usb-c-pd-and-pps-trigger-board-5a.html
