Product information
Arduino Leonardo is based on the ATmega32u4, which handles USB itself. This lets it appear to a computer as a keyboard or mouse, ideal for custom controllers and input devices.
It has 20 digital I/O pins (7 PWM, 12 usable as analogue inputs), a 16MHz crystal, a micro USB connection, a power jack, an ICSP header and a reset button. Choose it with or without headers.
