Low cost WiFi BADUSB

Overview

ESP8266+CH9328 DIY BADUSB keyboard (single panel, double-sided for proofing is no problem)

Source code (available in the attachment, the latest version will be released to GitHub if available): https://github.com/1452206376/ESP8266_BADUSB

# Important note (if you use the software serial port in the future, change it again)

## Connect the filter capacitor, connect the filter capacitor, connect the filter capacitor! ! ! Otherwise, it will be very unstable, and strange things will be entered if the keyboard is reset.

Now this version has changed the voltage regulator, but it is better to add a capacitor (why has the PCB picture not changed?)

## Use the configuration tool to configure the baud rate of CH9328 to 38400. The tool is in the attachment.
