CJMCU-CP2102 its highly integrated, built-in USB2.0 full-speed function controller, USB transceiver, crystal oscillator, EEPROM and asynchronous serial data bus (UART), supports full-featured modem signal without any external USB devices. CJMCU-CP2102 works with other USB-UART adapter circuit similar to the driver through the PC's USB port to a virtual COM port expansion in order to achieve the purpose.


CJMCU- gesture communication module USB to TTL module 5V power output TTL level kernel CJMCU-CP2102 CP2102 is a highly integrated USB-UART bridge to provide a minimum of components and PCB space to achieve a simple USB RS232 converter to solve program. Simply put, it is this: the user CJMCU-CP2102 USB interface and RS232 interface will be able to convert each other.



Original CP2102 chip to generate COM port after installing the driver.
