The CP210x is a family of USB-to-UART bridge controllers developed by Silicon Laboratories. These devices enable USB connectivity to devices that have UART interfaces, such as microcontrollers and embedded systems. CP210x devices offer features such as voltage regulators, programmable GPIO pins, and UART signal inversion. The devices are supported by a range of operating systems and require drivers for proper functioning. The CP210x Port Read/Write Example illustrates how the GPIO latch can be read from and written to. The CP210x-program project on GitHub provides an open-source tool for programming CP210x devices. The CP210x USB to UART Bridge Virtual COM Port (VCP) drivers are available on the Silicon Labs website.
