# How To Install Drivers for WCH CH34X / CH340 / CH341 / CH342 / CH343 / CH344 / CH346 / CH347 / CH9101 / CH9102 / CH9103 / CH9104 / CH9111 / CH9114 / CH9143 USB to Serial Chips ## Overview ![](https://cdn-learn.adafruit.com/assets/assets/000/120/906/medium800/arduino_compatibles_5400-13.jpg?1683669753) Certain boards, like the [ESP32 Feather V2](https://www.adafruit.com/product/5400), have a USB to serial converter chip that communicates between the processor and your computer. These chips require drivers to be installed on your computer's operating system. This guide will show you how to install the drivers for the WCH USB to serial chips - also known as CH9102F or CH9102. These chips are replacing the SiLabs chips, like the [CP2104](https://www.adafruit.com/product/3309) and [CP2102N](https://www.adafruit.com/product/5335), that have been used on Adafruit boards in the past. There are drivers for Windows and Mac computers available. If you're on Linux, the drivers are built-in. - [Next Page](https://learn.adafruit.com/how-to-install-drivers-for-wch-usb-to-serial-chips-ch9102f-ch9102/windows-driver-installation.md) ## Primary Products ### Adafruit WCH CH9102F Friend - USB to Serial Converter [Adafruit WCH CH9102F Friend - USB to Serial Converter](https://www.adafruit.com/product/5568) Long gone are the days of parallel ports and serial ports.
