for Arduino CP2102 module USB to TTL USB to serial UART for STC downloader
CJMCU-CP2102 has a high integration level and is equipped with a USB2.0 full speed functional controller, USB transceiver, crystal oscillator, EEPROM, and asynchronous serial data bus (UART). It supports full function signals from modems without the need for any external USB devices. The working principle of CJMCU-CP2102 is similar to other USB-UART adapter circuits, where the USB port of the PC is virtualized into a COM port through a driver program to achieve expansion.
1. The original CP2102 chip generates a COM port after installing the driver.
2. Connect standard MICRO MINI-USB cable input to computer USB interface, with two power outputs of 3.3V and 5V voltage
3. With self recovery fuse. In the event of an unexpected short circuit, it can effectively protect your downloader and computer USB port
4. On board status indicator light and transceiver indicator light. After the driver is correctly installed, the status indicator light will remain on, and the transceiver indicator light will flash during communication, with a running LED indicator light.
5. Supports baud rates from 300bps to 1Mbps
6. Communication format support: 1) 5,6,7,8 data bits; 2) Supports stop bits 1, 1.5, and 2; 3) Odd, even, mark, space, none verification
7. Supported operating systems: Windows 8.1/7/vista/xp/98, Mac OS-X/OS-9, Linux
8. The USB socket interface is a MICRO MINI-USB socket
9. The SMD components are welded by a legitimate company, with stable quality and beautiful appearance
10. With DTR trigger signal output, it can directly download program communication to for Arduino motherboards such as for Arduino pro mini ATMEGA328P.
11. Size: 22 * 16 * 4MM
Introduction to Drive Installation:
Instructions for use
1. First, open the installation package and proceed to the next step. Remember the installation directory
2. Start the service as follows
3. Find the driver in Device Manager, select Update Driver, browse the computer to find the driver, select the directory you just installed, confirm, and wait
Right click to update the driver, automatically search for the driver, and it will prompt that the driver data is invalid. In fact, this problem is often encountered in Windows 8, and the driver is not a problem. At first, it was not possible to install it, but later it was discovered that it may be due to hardware incompatibility.
If you are using Windows 8 or Windows 8.1, ghost or other non genuine systems, and have used various optimization tools to streamline and optimize the system, you may encounter an error of \"invalid data\" during the driver installation process
The solution to \'invalid data\' is as follows:
1. Press Winkey+R on the keyboard, enter \"services. msc\" in the \"Run\" dialog that pops up, and you can also find \"services\" in the \"Computer Management\" window;
2. Find the two service items \"Device Install Service\" and \"Device Setup Manager\" in the service list, and confirm whether these two services are enabled. If they are not enabled, you can click \"Start\" on the left side of the service.
