100% brand new and high quality it can't use for win8,please know it Economy Nano is in arduino NANO NANO base was modified, fully compatible with arduino NANO. The difference is that USB TO TTL, PL2303 chip using a cheap alternative FT232RL, PL2303 driver needs to be installed separately, win XP, win7, 32 bit can normally be used. Drivers can go to google search download, you can contact us PL2303 driver. http://prolificusa.com/pl-2303hx-drivers/ MicrocontrollerATmega328 Operating Voltage (logic level)5 V Input Voltage (recommended)7-12 V Input Voltage (limits)6-20 V Digital I/O Pins14 (of which 6 provide PWM output) Analog Input Pins8 DC Current per I/O Pin40 mA Flash Memory32 KB (ATmega328) of which 2 KB used by bootloader SRAM2 KB (ATmega328) EEPROM1 KB (ATmega328) Clock Speed16 MHz Dimensions0.73" x 1.70" This is a terminal adapter for the Arduino Nano. It lables for Arduino Nano version 3.0, however you can still use this adapter for the older version (just have to remember that A0-A7 are in the reverse order). You can use this adapter to easily hook up Arduino Nano to an outside world via hook up wires.
