Leonardo R3 Development Board - Compatible with Arduino

The Leonardo 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 specialty of Leonardo is that unlike UNO it has a built-in USB communication without the requirement of additional hardware, this enable the board to be used as HID devices like wireless mouse or keyboards.
• Along with Serial port (COM) communication it also supports Virtual CDC communication.
• Its operating voltage is 5V with recommended input voltage limit is 7-12V.
• You can use it as a replacement of Uno board if you want a greater number of Analog pins and PWM outputs with more processing power.
• Else you can check out Nano, Mega, pro mini etc.
• Specifications Operating Voltage: 5V Current O/P at GPIO pins: 40mA Flash Memory: 32KB SRAM: 2.5KB Clock Speed: 16MHz PWM channels: 7 Analog Pins: 12 Product Additional Resources Datasheet ATMega32u4 Getting Started with Leonardo Joystick Game controller with Arduino Leonardo Package contents 1×Leonardo Development Board.
