Adjustable power extension USBA plug-in

Overview

A simple and useful little plug-in
to take advantage of the ammeter mode of an adjustable power supply. It does not affect the original function of the power supply.
Key parameters are indicated in the drawings.

It can realize the key reminder of current monitoring of USB device power supply

. Be sure to confirm the voltage before powering on. The USB high-voltage input of some devices is risky.
The BOM list only has vertical plug-in USBA. You can buy it on Taobao. It has been done in small batches and there are no problems.
The installation method can be understood at a glance. More pictures will be added in the future. There are no ads or sensitive images. Please review, brother, don’t block me.

Mobile power management
For portable devices, power management is a very important and key component. Power management ICs are usually divided into integrated and discrete types, and the integrated type is also called power
Has anyone used the AD831 chip?
Will my AD831 chip reverse the output? When my AD831 outputs a signal with the same frequency and phase, after the output is low-pass filtered, theoretically it should be a positive DC bias.
【Circuit Appreciation】 Anti-reverse connection circuit
This circuit is a circuit in an article published by zero3360 in the automotive circuit section. It is very classic. Specially share with you
Summary of some ground loops
Ground loops are like "magical creatures" that appear and disappear like ghosts, leaving only a trace on your oscilloscope. You may not know when a ground loop occurs when using electronic equipment n
