Usb 2.0 To Ttl Uart Serial Converter Cp2102





CP2102 its high integration, built-in USB2.0 full-speed function controller, USB transceiver, crystal oscillator, EEPROM, and asynchronous serial data bus (UART), supports full-featured modem signals, without any external USB device. CP2102 with other USB-UART adapter circuits works similar to the PC through the driver’s USB port into a virtual COM port in order to achieve the purpose of expansion.
