Arduino Leonardo with Headers — Arduino Official Store
Arduino Micro with Headers - 5V 16MHz - (ATmega32u4 - assembled) : ID 1086 : $24.95 : Adafruit Industries, Unique & fun DIY electronics and kits
The Micro is a microcontroller board based on the ATmega32U4, developed in conjunction with Adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a micro USB cable to get started. It has a form factor that enables it to be easily placed on a breadboard.
