Leonardo R3 ATMEGA32U4 IDE 1.0.3 Arduino Compatible w/ USB cable

Leonardo R3 ATMEGA32U4 IDE 1.0.3 Arduino Compatible w/ USB cable

Description:
- The design of the board is exactly based on the open source official Arduino schematics.
- The logo on the board and color of usb cable may be different from different production series.
- Arduino Leonardo is a the Arduino team recently launched low-cost Arduino controller . It has 20 digital input and output ports , 7 PWM ports and 12 analog input . Compared to other versions of the Arduino using a separate USB-Serial converter chip uses a single-chip solution , the Leonardo innovative . Only with a Atmega32u4 USB communication and control . This innovative design reduces the cost of Leonardo . The original ecological support Atmega32u4 USB characteristics can let the Leonardo modeled as the mouse and keyboard , and greatly improve the applications . Arduino Leonardo need Arduino IDE1.01 version of the new version of the . Arduino Leonardo and ordinary Arduino , there are some obvious differences , the specific content can be found in the the Arduino Leonardo guidance document :arduino.cc/en/Guide/ArduinoLeonardo
