In general, it is best to operate the display off of 5V to ensure enough power is available. Be careful of trying to operate the display from the built-in 3.3V available on Arduino and similar microcontrollers since these power sources often have limited current capability and may overheat.

This 2.8-inch SPI TFT LCD Touch SD card with Stylus has a 240 x 320 pixels resolution.
It uses the ILI9341 controller with an SPI interface.
It also includes a resistive touchscreen with a built-in XPT2046 controller.
These full-colour displays are large enough for many applications, even when using touch.
The supplied Stylus is helpful when using smaller touch targets.
The modules have an SD card socket. This socket has separate connections to the opposite end of the board.
Internally, the display operates at 3.3V, so if using a 5V microcontroller, include logic level shifters on the data lines to prevent possible damage.
Package included: 1x 2.8-inch SPI TFT LCD SD card Touch with Stylus
Arduino Arduino TFT library
The module power comes in on the VCC pin. The module includes an onboard 3.3V regulator, so the module should normally be operated off of 3.6 to 5.5V power on this pin to feed the regulator. Current is typically 55-60mA
If you would prefer to operate the module directly from a 3.3V power source, there are two solder pads labelled J1. The regulator is bypassed by solder shorting these two pads together, and the module can be powered directly from 3.3V.
In general, operating the display off of 5V is best to ensure enough power is available. Be careful of trying to operate the display from the built-in 3.3V available on Arduino and similar microcontrollers since these power sources often have limited current capability and may overheat.
This display incorporates the SPI interface, which provides for fast display updates. It is a 4-wire interface with a CS (Chip Select).
The touch screen also uses the SPI interface and can hook to the same pins as the display. It does use a separate CS to avoid conflict.
A hardware SPI interface should be used for the best performance to get the fastest screen updates.
The SD card socket comes out to solder pads on the opposite end of the module.
