1. CJMCU-CP2102 has high integration, built-in USB2.0 full speed function controller, USB transceiver, crystal oscillator, EEPROM and asynchronous serial data bus (UART), supporting modem full-function signal, without any external USB device.
2. CJMCU-CP2102 is similar to other usb-uart transfer circuits in working principle. The USB port of PC is virtual to com port through driver to achieve the purpose of expansion.
3. CJMCU module communication USB to TTL module 5V power output TTL level CP2102 core CJMCU-CP2102 is a highly integrated usb-uart bridge, which can provide a simple solution to realize RS232 to USB conversion by minimizing the space of components and PCB. Simply put: users can use CJMCU-CP2102 to convert USB interface and RS232 interface.
1. 2102 chip. COM port is generated after the driver is installed.
2. Connect standard micro mini-USB cable input to USB interface of computer, with 3.3V and 5V power output.
3. On board status indicator light and transceiver indicator light. After the driver is installed correctly, the status indicator light will always be on, and the transceiver indicator light will flash when communicating, with operation led indicator light.
4. Support baud rate from 300bps to 1Mbps.
5. Communication format support: 1) 5,6,7,8 bits of data; 2) 1,1.5,2 stop bits; 3) odd, even, mark, space, none verification.
6. Supporting operating system: Windows 8.1/7/vista/xp/98, for MAC OS-X / OS-9, Linux.
7. The USB port is MICRO MINI-USB port.
8. SMD components are welded by regular company, with stable quality and beautiful appearance.
9. With DTR trigger signal output, it can directly download program communication to Pro Mini ATMEGA328P and other mainboards.
