Sometimes it happens that when playing with electronics, we need more than 5V or 9V. USB PD Power Supply Solves this issue.
By using USB PD Protocol, it can negotiate more than 5V from the USB PD charger. It can give voltage outputs as supported by the PD charger from 5V to 20V and it also supports the new USB PPS protocol which allows us set the voltage according to our own needs. For Example, if some device needs 18V, PPS can do the task and it could supply voltage..

USB PD Power Supply can use both PD and PPS to cupply voltage. The microcontroller is the OG RP2040, which communications with the AP33772SDKZ USB PD negotiator IC to negotiate voltage levels. The Voltage and max current settings are controllable using the two rotary encoders present on the PCB.

First of all, you start with the gerber and upload it to your desired pcb manufacturer, I am gonna use PCB Power. Now you order the PCB and all the components, and you wait, after they arrive, you cook(assemble) the PCB. Then what you do is that you upload the code and start using, 3D printed case is optional but you could download the files for that too! Flash firmware(firmware to come in a few days) on RP2040 using thonny or other software and boom your USB-PD-Power-supply is ready

I chose to make this project mainly because of the power issues i face. A few days ago, I wanted to power a coil for an electromagnet, i was not able to power it because of power supply from the Power bank (5V) was not enough, so i had the idea of making this because my dad's phone has a USB PD Charger so i could use that charger to power electronics that require higher voltage. That type of a project would be too simple, so i also added two rotary encoders and make a dedicated power supply.
