Touch screen Adafruit LCD display 2,8'' 320x240px + microSD reader - Adafruit 1770

Product description:TFT LCD 2.8'' 320x240px Adafruit touch screen display with microSD reader

2.8" TFT LCD touch screen graphic display with 320 x 240 px resolution and 18-bit colour depth. It works with both 3.3 V and 5 V. Additionally, there is a micro SD memory card reader on the board.

The screen is based on the ILI934 controller and has a built-in RAM memory, so the microcontroller is not burdened with display control. The device can communicate in two modes: 8-bit mode and via SPI bus. For 8-bit mode, eight digital data lines and four control lines must be connected. SPI requires only five transmission lines, but is slower than 8-bit communication. In addition, four additional pins are required to operate the touch screen.

The leads areholes for the includedgoldpin connector- 2.54 mm raster (for self-soldering). They allow for connection of the display through wires or plugged into the contact plate.

Thanks to the built-in voltage converter the system works with both 3.3 V and 5 V logic. The installed slot allows to provide graphic files on micro SD card with FAT16/FAT32 system.
