[LED/LCD Display Module] Since the 1.8 Inch TFT LCD Module display uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. Even a very small one with low memory and few pins available! The 1.8″ display has 128×160 colour pixels. Unlike the low cost “Nokia 6110” and similar LCD displays, which are CSTN type and thus have poor colour and slow refresh, this display is a true TFT! The TFT driver (ST7735R) can display full 18-bit colour (262,144 shades!). And the LCD will always come with the same driver chip so there are no worries that your code will not work from one to the other. The breakout has the TFT display soldered on (it uses a delicate flex-circuit connector) as well as an ultra-low-dropout 3.3V regulator and a 3/5V level shifter so you can use it with 3.3V or 5V power and logic. We also had a little space so we placed a microSD card holder so you can easily load full-colour bitmaps from a FAT16/FAT32 formatted microSD card.
