![]() ![]() ![]() The SD card socket comes out to solder pads on the opposite end of the module. The number do not match, so use one of the following combinations. You will also need to set the rotation of the touch screen. Use setRotation(n) to rotate the image to match the physical rotation where n ranges from 0 to 3. The display can be rotated in all 4 directions. It does use a separate CS to avoid conflict.įor best performance a hardware SPI interface should be used if possible to get the fastest screen updates. The touch screen also uses the SPI interface and can hook up to the same pins as the display. It is a 4-wire interface so includes a CS (Chip Select). This display incorporates the SPI interface which provides for fast display updates. 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. In general, it is best to operate the display off of 5V to ensure enough power is available. By solder shorting these two pads together, the regulator is bypassed and the module can be powered directly from 3.3V. If you would prefer to operate the module directly from a 3.3V power source, there are two solder pads labeled J1. The module includes an on-board 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. The module power comes in on the Vcc pin. Internally the display operates at 3.3V, so if using with a 5V microcontroller, be sure to include logic level shifters on the data lines to prevent possible damage. This socket has separate connections to the opposite end of the board. The supplied stylus is helpful when using smaller touch targets. These full color displays are large enough for many applications even when using touch. Resistive touch screen with XPT2046 controller.KEY FEATURES OF TFT LCD 2.8″ 240×320 DISPLAY WITH TOUCHSCREEN : TFT LCD 2.8″ 240×320 RGB Display with ILI9341 controller and touchscreen.Same as our 3.2″ version, just a little smaller and a little less expensive. It also includes a resistive touchscreen with built-in XPT2046 controller. It uses the ILI9341 controller with SPI interface. This 2.8″ TFT LCD is a full color display with a resolution of 240 x 320 pixels or 320 x 240 pixels depending on how it is oriented. ![]()
