Overview

This is a new SainSmart Leonardo R3 kit, which is easy for Arduino fans and starters to plug and play, containing one SainSmart Leonardo R3, one SainSmart IIC LCD2004.

 

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.
