USB UART 3 click is a versatile and feature-rich USB to UART interface from Silicon Labs. It uses CP2102N which is a part of their USBXpress™ family. These devices are designed to quickly add a USB 2.0 full-speed compliant UART interface for custom applications, by eliminating firmware complexity and reducing development time. The Click board™ requires appropriate drivers to be installed in the host OS, in order to support the virtual COM port functionality. Once installed, this device offers amazing connectivity options, up to 3 Mbaud, a very low number of external components, simplified setup of the advanced options via the GUI-based configurator (if required), out-of-the-box functionality with the royalty-free virtual COM port drivers, provided by the Silicon Labs.
