I saw in matters other guests talked about the touch, driver etc ... Except that I did not at all what they have. The controller is a HX8347 (drivers are difficult to find), it lacks indication (screen printing) on the back of the card (the pines of touch, for example). I have an Arduino Mega board and it's a hassle to turn. Maybe it work with UNO. It is a parallel port for read / write.
