Previous experience in soldering is essential. The module can be damaged via improper installation.
Setting up the internal keylogger is a simple solder job. The internal keylogger is designed to fit inside a keyboard. It is recommended to make sure the keyboard is compatible before installation. Keyboards using non standard HID protocols may not be compatible eg: Gaming Keyboards
A USB cable typically has 4 wires POWER, GROUND, DATA+, DATA-
The idea is to expose the wires on the keyboard’s USB connection and solder these wires to the corresponding pad on the KeyLogger module. The keylogger acts as a passive tap.
The KeyLogger comes labelled with the corresponding wires each pad should be soldered to.
Once tinned, a wire is much easier to solder to a pad.
Close up the keyboard, making sure none of the wires make contact with eachother.
Follow the first use tutorial just like you would a non-internal KeyLogger.
