Funduino Leonardo R3

Funduino Leonardo is the latest low-cost controller. It has 20 digital input and output ports, 7 PWM ports, and 12 analog inputs. Compared to other versions of the Arduino using a separate USB-Serial converter chip, Leonardo innovative uses a single-chip solution. It only took a Atmega32u4 to realize USB communication, and control. This innovative design reduces the cost of Leonardo. Atmega32u4 the original ecosystem supports USB features also allow Leonardo simulate mouse and keyboard, which greatly improved the applications. Leonardo need to use the new version of Ardu IDE1.01 later.
