USB Multi-functional Cement Loader

Overview

This is a cement load, but more than just a cement load!!!

Project origin:
I made a charging module (PS: SW3518S in my project), and I wanted to test the charging ripple of my module. However, as we all know, whether it's a mobile phone or a computer, the power, current, and voltage change over time during charging, and the timing of these changes varies depending on the device's charging strategy. This makes it difficult to control the variables during testing, so I DIYed a load using a cement resistor.

Highlights:

1. Straight-through mode ➡️
A single cement load is a bit...
