USB power meter WeChat version

Overview

USB galvanometer (WeChat applet version)

V1.0

It is characterized by simplicity and low cost, and you can just use the WeChat applet to receive it. No Bluetooth connection is required, but Bluetooth reception needs to be turned on. (This is the first time this application has been launched on the Internet, that’s what I’m saying)

Just search for "Simple Power Meter" on WeChat .

Connect the adapter board and scan the QR code on WeChat to view the voltage, current, power and other parameters currently passing through the adapter board. No binding or connection required.

Notes and instructions
Bluetooth must be turned on.
The data update speed varies from mobile phone to mobile phone, usually the update cycle is about 3 seconds.
