A USB-to-serial converter is a device that allows a computer or other USB-enabled device to communicate with a serial device, such as a microcontroller, PLC, or scientific instrument, over a USB connection. The converter essentially translates the USB data sent by the computer into serial data that can be understood by the serial device, and vice versa.
A USB-to-serial converter typically consists of a small hardware adapter that connects to the USB port of the computer and a serial cable or connector that connects to the serial device. The converter may include a microcontroller or other chip that performs the conversion between USB and serial data.
USB type C to serial converters is commonly used in a variety of applications, such as industrial automation, scientific research, and hobbyist electronics.
