The exact same ATmega328P processor found on the Arduino UNO boards, but in 32-pin surface mount. http://www.atmel.com/Images/Atmel-42735-8-bit-AVR-Microcontroller-ATmega328-328P_Summary.pdf
NOTE!! This micro does not come with the Arduino Bootloader pre-flashed. You can do this easily by using an existing Arduino board, and can simply contact us if you need assistance or more information on how to do so.
