Driver Installation

To evaluate and develop the X4 under Windows, you need to install the serial port driver of the USB
adapter board. The USB adapter board of this kit adopts CP2102 chip to realize serial port (UART)
to USB signal conversion. Its driver can be downloaded from our official website or downloaded
from the official website of Silicon Labs:

After extracting the driver package, run the CP2102's Windows driver installation file (exe file under
CP210x_VCP_Windows). Please select the 32-bit version (x86) or 64-bit version (x64) installation
program according to the version of the windows operating system.
