PD power supply

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 just feels a bit hot when running.)

This project consists of two projects. This project is the base plate.
The top board connection is: https://oshwhub.com/surpmotherfucker/pd-dian-yuan-ding-ban

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.

Tesla Coil 2 "Low Power Discharge + Detailed Pictures" Welcome to guide
Today is Saturday, December 8, 2018. I made a big coil two days ago to see the effect. I first made a small-power effect. The specific details are as follows. Welcome to the guidance of all the expert
Software emulation of MCU file system finally succeeded!!
During this period, I needed to build a file system running on a single-chip microcomputer. As the hardware was not good, I had to write a disk simulation DLL and create a pure software simulation env
