SainSmart 3.2" TFT LCD Display +FT LCD Adjustable Shield for Arduino UNO Mega2560 R3 (with Mega2560)
3.2" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and multifunctional module for your project. The Screen include a controller SSD1289, it's a support 8/16bit data interface , easy to drive by many MCU like STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is ADS7843 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.
3.2 TFT LCD shield works in 3.3V voltage level and you need to use cables to connect with Mega. And this shield can help you out of the bothers to use other cables. You just need to plug the module to Mega through this shield. It supports both 16 bit mode. And Mega board has enough pins for using SD card and touch function at the same time. It also has an adjustable button for contrast of the LCD display.
MEGA 2560 Board is based on the ATmega2560. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a 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.
MEGA2560 R3 uses an ATMega16U2 which allows for faster transfer rates and more memory. No drivers needed for Linux or Mac, and the ability to have the Uno show up as a keyboard, mouse, joystick, etc. It also adds SDA and SCL pins next to the AREF. The MEGA2560 R3 works with all existing shields but can adapt to new shields which use these additional pins.ns.
