CP2102 USB to TTL Converter

CP2102 USB to TTL UART Converter

The CP2102 USB to UART/TTL Converter Module provides a serial port for your computer, i.e. a virtual COM port to connect to a serial device. The IC used CP2102 is stable and reliable. It supports baud rates from 300bps to 1.5Mbps and driver support for a wide range of Operating Systems. This is a great little tool for embedded systems that require a serial connection to a computer. The board can simply attach to a USB bus and will appear as a standard COM port.

ThisCP2102 doesn't require any external oscillator, it onboard-board voltage regulator, and it even uses a reprogrammable internal EEPROM for the device description. The full hardware UART has flow control for baud rates from 300bps to 921600bps.

This breakout also allows you to connect the TX/RX pins of your favorite microcontroller or serial application to the RX/TX pins of the breakout, creating a simple serial cable replacement.
