Arduino Leonardo R3 Clone

 

Arduino Leonardo has ATmega32u4 microcontroller. 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 includes everything needed to support the microcontroller; Connect it to a computer via USB cable and power it with an adapter or battery to get started. It is different from cards. In this way, the controller can operate as a HID device (such as a mouse or keyboard) as a virtual COM interface.
