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 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.
