3.5″ TFT 320×480 Touchscreen Breakout Board w/MicroSD Socket – HXD8357D

Description

Add some jazz & pizazz to your project with a color touchscreen LCD. This TFT display is big (3.5″ diagonal) bright (6 white-LED backlight) and colorful! 480×320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128×64 display, and double our 2.8″ TFT. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

This display has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. The display can be used in two modes: 8-bit or SPI. For 8-bit mode, you'll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and d/c) but is slower than 8-bit mode. In addition, 4 pins are required for the touch screen (2 digital, 2 analog) or you can purchase and use our resistive touchscreen controller (not included) to use I2C or SPI.

Of course, we wouldn't just leave you with a datasheet and a “good luck!”. Check out our detailed tutorial for wiring, test and example code!For 8-bit interface fans we've written a full open source graphics library that can draw pixels, lines, rectangles, circles, text, and more. For SPI users, we have a library as well, its separate from the 8-bit library since both versions are heavily optimized. We also have a touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it.

Specifications:

3.5″ diagonal LCD TFT display
320×480 resolution, 18-bit (262,000) color capable – our code uses only 16-bits since its faster.
HXD8357D (datasheet) controller with built in video RAM buffer
8 bit digital interface, plus 4 or 5 control lines (12 pins minimum) or SPI mode with 4 or 5 SPI data/control lines (4 pins minimum) – not including the touch screen.
5V compatible! Use with 3.3V or 5V logic such as an Arduino
Onboard 3.3V @ 150mA LDO regulator
6 white LED backlight with DC/DC constant-current boost. You can PWM dim the backlight
1×20 headers for easy breadboarding
4-wire resistive touchscreen
