CP2102 module USB to TTL USB to serial UART STC downloader

The MCU-CP2102 is highly integrated, with built-in USB2.0 full speed function controller, USB transceiver, crystal oscillator, EEPROM and asynchronous Serial Data bus (UART), supporting the modem full function signal without any external USB device. The CJMCU-CP2102 works similarly to other USB-UART switching circuits by virtualizing the PC's USB port into a COM port through a driver to achieve the purpose of expansion.

Cjmcus - Attitude Module Communication USB-to-TTL module 5V Power Output TTL level CP2102 Core CJMCUs -CP2102 is a highly integrated USB-UART bridge that provides an easy solution for RS232 to USB using minimal components and PCB space. To put it simply, the user can convert the USB interface to the RS232 interface using the CJMCU-CP2102.

Module description:

1, the original CP2102 chip, the COM port is generated after installation.

2, Connect to the standard MICRO MINI-USB cable input to the computer USB interface, with 3.3V and 5V voltage two power output

3, with self-recovery fuse. In the event of an unexpected short circuit, it can effectively protect your downloader and computer USB port

4, the on-board status indicator and transceiver indicator light, the status indicator light will be steady after the correct installation of the driver, the transceiver indicator light will blink during communication, with the operation LED indicator light.

5, support from 300bps to 1Mbps baud rate

6, communication format support: 1) 5,6,7,8 data bits; 2) Support 1,1.5,2 stop bits; 3) odd,even,mark,space,none check

Driver installation introduction:

Instructions for use

win7/win8

1, first open the installation package, all the way next, remember the installation directory

2. Start the service as follows

3. Find the driver in the device manager, select the update driver, browse the computer to find the driver, select the directory just installed, and wait after determining

win8.1

Right click to update the driver, automatically find the driver, will prompt the driver data is invalid, in fact, this problem is often encountered under windows8, the driver is no problem, the beginning has not been installed, and later found that the hardware may be incompatible.

If you use the system is Windows8 or windows 8.1, and is ghost or other non-legitimate system, and have used a variety of optimization tools to streamline the optimization system, then in the process of installing drivers, you may encounter "data invalid" error

The "data invalid" solution is as follows:

1. Press Winkey+R on the keyboard, enter "services.msc" in the pop-up "Run" dialog, or find "Service" under the "Computer Management" window;

2. Find "Device Install Service" and "Device Setup Manager" in the service list and check whether these two services are enabled. If they are not enabled, click "Start" on the left
