Description:
CP2102 its highly integrated, built-in USB2.0 full-speed function controller, USB transceiver, crystal oscillator, EEPROM and asynchronous serial data bus (UART), supports full-featured modem signal without any external USB devices. CP2102 works with other USB-UART adapter circuit similar to the driver through the PC"s USB port to a virtual COM port expansion in order to achieve the purpose.
This communication module USB to TTL module 5V power output TTL level kernel CP2102 is a highly integrated USB-UART bridge to provide a minimum of components and PCB space to achieve a simple USB RS232 converter to solve program. Simply put, it is this: the user CP2102 USB interface and RS232 interface will be able to convert each other.

This is the best USB/Serial "friend" IMHO. It has a micro USB port for connections, has the CP2102 USB2Serial chip, which is the most compatible and verastile on the market today. Has 5V and 3.3V signaling, so perfect for all my projects. The price is awesome. This is the best bang for the buck amongst all TTL serial converters. I almost always end up using this so I am thinking about getting a second one. :) This version comes with straight pins, that are perpendicular to the board. I ended up beding the pins 90 degrees, so it is a flatter and a more streamlined cable-like costruct this way.
