Features

SainSmart Leonardo R3 Improved Version Board

The SainSmart 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.
