CJMCU-Posture Module Communication USB to TTL Module, 5V Power Output, TTL Level CP2102 Core. The CJMCU-CP2102 is a highly integrated USB-UART bridge, providing a simple RS232 to USB conversion solution using minimal components and PCB space. Simply put, the CJMCU-CP2102 allows users to convert USB interfaces to RS232 interfaces and vice versa.

Module Description:
1. Original CP2102 chip, which generates a COM port after driver installation.
2. Connects to a computer USB port using a standard MICRO MINI-USB cable input, with 3.3V and 5V power outputs.
3. Includes a resettable fuse to effectively protect your downloader and computer USB port in the event of an accidental short circuit.
4. Onboard status and transmit/receive indicators. The status indicator will be solid when the driver is correctly installed, and the transmit/receive indicator will flash during communication. Also includes an operation LED indicator.
5. Supports baud rates from 300bps to 1Mbps.
6. Supported communication formats: 1) 5, 6, 7, and 8 data bits; 2) 1, 1.5, and 2 stop bits; 3) odd, even, mark, space, and none parity.
7. Supported operating systems: Windows 8.1/7/Vista/XP/98, Mac OS-X/OS-9, and Linux.
8. MICRO MINI-USB USB connector.
9. SMD components are soldered by a reputable company, ensuring stable quality and an attractive appearance.
10. Equipped with a DTR trigger signal output, it can directly communicate with motherboards such as the Arduino Pro Mini and ATMEGA328P for program downloads.
11. Module size: Super compact, 16mm*20mm.

Driver Installation Overview:
Instructions
Win7/Win8
1. First, open the installation package and click Next. Remember the installation directory.
2. Start the service as follows.
3. Find the driver in Device Manager, select Update Driver, browse your computer for the driver, select the directory you just installed, confirm, and wait.
Win8.1
Right-click the driver and it will automatically search for the driver. You may get a message saying the driver data is invalid. This problem often occurs in Windows 8. The driver is fine, but it may not install initially. Later, it turns out it may be due to hardware incompatibility. If you’re using Windows 8 or Windows 8.1, running Ghost or another non-genuine operating system, and have used various optimization tools to streamline and optimize the system, you may encounter an “Invalid Data” error during driver installation. Here’s how to fix this:
1. Press Winkey+R on your keyboard and enter “services.msc” in the “Run” dialog box that pops up. You can also find “Services” in the “Computer Management” window.
2. In the services list, find “Device Install Service” and “Device Setup Manager” and confirm whether these services are enabled. If not, click “Start” on the left to enable them.
