Leonardo Atmega32u4 (100% compatible with Arduino IDE)

Description

CANADUINO Leonardo (100% compatible to Arduino Leonardo and Arduino IDE) is a microcontroller board based on the ATmega32u4. 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, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

The Leonardo differs from all preceding boards in that the ATmega32u4 has built-in USB communication, eliminating the need for a secondary processor. This allows the Leonardo to appear to a connected computer as a mouse and keyboard, in addition to a virtual (CDC) serial / COM port.

Its RAM size of 2.5kB is still very limited, but already 25% bigger than that of an Arduino UNO or Nano with Atmega328P, allowing for more memory-hungry applications like driving of larger WS2812B addressable LED setups.
