PD power top plate

Overview

With it you will get 1×PD input low-power buck-boost power supply (OUT MAX: 40V 40W) 1×PWM generator 1×voltage ammeter

can be set to decoy 5V, 9V, 12V, 15V, 20V all PD power supply

3.5*6cm The mini size
has a huge screen-to-body ratio (fog),

which is really a good thing.
(It is a bit hot when running)

This project consists of two projects, this project is the roof. For the driver, see the attachment . The
bottom board connection is: https://oshwhub.com/surpmotherfucker/pd-newcurr

Note: Before using its ammeter function, please connect the OUT+ points of the two boards with wires, otherwise the voltage drop will be large and the current value will be inaccurate.
