Seeedstudio 2.8’’ TFT Touch Shield V2.0 is a multifunctional Arduino/Seeeduino/Arduino Mega compatible resistive touch screen. It can be used as display device or sketch pad. Compared with the previous version, 2.8’’TFT Touch Shield V1.0 , the screen driver is replaced with a more professional chip, ILI9341 driver, providing different pin-saving SPI communication without sacrificing the data transmitting speed. Due to the communication method change, programs developed for the previous version need modifications before being transplanted to the new version. With an SD card module integrated also on Seeedstudio 2.8’’ TFT Touch Shield V2.0, this shield reserves great room for other expansions to your project.
