We now introduce a new 2.8” display, this is in the form of an Arduino shield and works with 3.3V or 5.0V, which means it work with most hardware with an Arduino pin header.
It has a great 320x240 TFT screen and also features a resistive touch screen, micro-SD card slot and a 4MB flash memory. With all these features enabled there are still 11 pins free on the Arduino header (D0, D1, D3, D5, D7 and A0->A5).
It runs at full speed on both Arduino UNO and Arduino Mega, just use the onboard switch to select hardware platform. No hardware modification or soldering required. Check it out at: here
