128x128 1.45


Add some dazzle to your project with this 1.45" diagonal graphic TFT display module. This small display packs 128x128 full-color pixels into one square inch of active display area. It is a great choice when you need color and sharp detail while using minimal front panel space. At less than 5 grams, the display adds very little weight to handheld devices.

Thanks to the integrated Sitronix ST7735S or compatible controller, a single 3.3v source powers everything. The SPI host interface allows full read and write control of the display while using only 10 pins. The single bright white LED backlight has anode (A,+) and cathode (K, -) pins brought out on the Flexible Printed Circuit (FPC) tail. To connect, all you need is a standard 10-conductor, 0.5 mm ZIF socket such as Omron Electronics XF2L-1025-1A sold by Digi-Key.

Arduino + TFT Display Demo Using Simple SPI Interface

While the SPI interface requires only a few lines to control this TFT LCD module, it is still possible to transfer data at a rate that supports 20 FPS (Frames Per Second) screen updates -- fast enough to play a full motion video.

The project write-up on how to connect this TFT, including the Arduino Sketch is on our forum.

To get started, download the datasheet and SPI sample code. And of course, Crystalfontz is always here to help you when you integrate this display into your application.
