The USB-SERIAL CH340K is a USB-to-serial adapter chip commonly used for converting USB signals to a standard serial communication (RS-232, TTL, etc.) format. It's often found in devices like Arduino boards, microcontroller-based projects, or other embedded systems that need serial communication with a computer.
The CH340K chip is manufactured by WCH (Nanjing Qinheng Electronics), and its corresponding Windows driver is needed to enable your operating system to recognize and communicate with the device via the USB port.
