= Key Features =
Native USB Support - ATmega32u4 handles USB directly, enabling HID functionality[citation:6]
Keyboard/Mouse Emulation - Appears as HID device to computer[citation:1][citation:4]
High Analog Count 12 analog inputs for sensorrich projects[citation:1]
40mA I/O Current Higher perpin current than standard Arduino boards[citation:3]
ICSP Header - Supports SPI communication and firmware programming[citation:4]
√ USB Cable included in package
√ Works with existing Arduino shields
√ Official board with quality certification
Connect the Leonardo R3 to your computer using the included USB cable[citation:4]. Open Arduino IDE, select *Tools > Board > Arduino Leonardo*, then select the correct COM port[citation:4]. Upload your sketch directly - no additional programmer needed.
The ATmega32u4's native USB means the board appears as a keyboard, mouse, or joystick to the computer, enabling creative HID applications[citation:6].
Plug and Play - USB cable included for instant connection
IDE Compatible - Standard Arduino programming environment[citation:4]
√ LED pin 13 for basic testing
√ Reset button and power jack included
√ Compatible with Arduino shields[citation:9]
