USB to UART Connectivity Bridges

Our USB to UART devices are highly optimized solutions created to enable designers to easily add USB to existing and new applications. The fixed function devices provide the easiest method to add USB without the need for any firmware or driver development. The USBXpress portfolio supports several USB to serial bridge devices, including human interface (HID) devices and USB Audio devices. Additionally, our Driverless USB to UART portfolio features a CDC driver, which further simplifies the integration process by enabling seamless communication between USB and UART interfaces without the need for custom USB driver installation.
