#713 USB Multifunction Tester

Examining the KWS-MX17 inline USB multi-function tester

Build

Notes

The KWS-MX17 device sites inline and monitors USB voltage, current, power, timing and temperature. It is very handy for keeping an eye on current drawn by an appliance for example.

It is widely available, for example from sellers on aliexpress, with listings such as: 8 in1 QC2.0 3.0 4-30v Electrical power USB capacity voltage tester current meter monitor voltmeter ammeter

About LEAP

LEAP is my personal collection of electronics projects - usually involving an Arduino or other microprocessor in one way or another. Some are full-blown projects, while many are trivial breadboard experiments, intended to learn and explore something interesting.

Projects are often inspired by things found wild on the net, or ideas from the many great electronics podcasts and YouTube channels. Feel free to borrow liberally, and if you spot any issues do let me know or send a pull-request.

NOTE: For a while I included various scale modelling projects here too, but I've now split them off into a new repository: check out LittleModelArt if you are looking for these projects.
