USB to TTL with Silabs CP2102 chip

Brand new and high quality. PCB Dimensions: 26.5mm * 15.6mm PCB Color: Black Weight: 4g using a new chip factory in 2013 CP2102 with self-recovery fuse. In the event of accidental short circuit, it can effectively protect your computer USB port and Downloader with three LEDs: power indicator, data reception indicator, the data transmission indicator, working status with 3.3V and 5V dual power output pin leads to all sorts of useful with reset signal output, etc. directly to the FOR ARDUINO board Promini download! Supported operating systems: Windows 98/Me/2000/XP/7 OS-9 OS X-Windows CE Linux 2.40 or later CP2102 its high integration, built-in USB2.0 full-speed function controller, USB transceiver, crystal oscillator, EEPROM, and asynchronous serial data bus (UART), supports full-featured modem signals, without any external USB device. CP2102 with other USB-UART adapter circuit works similar to the PC through the driver's USB port into a virtual COM port in order to achieve the purpose of expansion.
