Note: This product is discontinued, but you can purchase the Seeeduino Lite, which is an equivalent alternative that can be used instead.
The Arduino Leonardo is a microcontroller board based on the ATmega32u4. It has 20 digital input/output pins 7 of which can be used as PWM outputs and 12 as analogueue inputs a 16 MHz crystal oscillator a micro USB port a power supply jack an ICSP header and a reset button. It contains everything was needed to support the microcontroller; simply connect it to a computer with a USB cable or supply it with an AC/DC adapter or a battery to get started.
