Add some dazzle to your project with this 1.45" diagonal 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.

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 (see video below). At less than 5 grams, the display adds little weight to a handheld device.

Thanks to the integrated Sitronix ST7565P controller, you only need a single source 3.3v for both power supply and LED backlight. 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 FPC tail (Flexible Printed Circuit). To connect, all you need is a standard 10-conductor, 0.5 mm ZIF socket such as a SFV10R-2STE1HLF.
