Introduction
For beginners to Arduino it can be daunting and risky to wire LCD driver circuits - one wrong
connection and your component can be damaged. This LCD expansion board removes all the
complications and risks.
The TELEMATICS 3.5" TFT Touch LCD Shield is an Arduino compatible display designed by
DFRobot, with a resolution of 320x480, three serial ports and one IIC interface. It is perfectly
compatible with Arduino DUE, Mega1280/2560, and Bluno Mega1280/2560. There is an on-board
voltage switch which supports changing the output voltage between 3.3V and 5V to ensure that it
won't damage your DUE. In addition, the LCD shield comes with a MicroSD card slot on the back
that can be used for data storage up to a maximum of 32GB. We also offer a variety of driver
packages to help you implement different features.
Note: Since the operating voltage of DUE and MEGA are different, the backlight
brightness will change if you replace your Arduino platform. Please adjust the D8 PWM
signal to control the brightness of the backlight

Sample Code 1
In this section, we'll explain how to initialize the LCD screen. You can use
"setFontSize"
and
"setColor"
function to change the font and the color of the characters
