Description
This 2.2" 18-bit color TFT LCD display breakout uses 4-wire SPI to communicate and has its own pixel-addressable frame buffer, it can be used with every kind of microcontroller. The breakout has 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 and a microSD card holder so you can easily load full-color bitmaps from a FAT16/FAT32 formatted microSD card.
