Overview

The SainSmart Leonardo R3 for Arduino is a microcontroller development 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
provides everything needed to support the microcontroller; simply power it with
a AC-to-DC adapter to get started. A battery may also be used, or it can get
power from the USB port.

SainSmart IIC/I2C/TWI Serial 2004 20×4 LCD Module Shield, a new high-quality 4
line 20 character LCD module not only set the contrast control knob selector
switch also has a backlight and IIC communication interface. For Arduino
beginners, not for the cumbersome and complex LCD driver circuit connection and
a headache, the real significance of this LCD module will simplify the circuit,
this module directly into the Arduino Sensor Shield V5.0 sensor expansion board
IIC device interface can, GM 4P sensor connection cable, programmed through the
Arduino controller, you can easily identify the slogan, sensor data records.
