Product description:TFT LCD 3.5'' 320x480px Adafruit touch screen display with microSD reader
3.5" TFT LCD touch screen graphic display with 320 x 480 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 HXD8357D controller, it has a built-in RAM memory, so the microcontroller is not loaded with the display control. The device can communicate in two modes: 8-bit and through the 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.
