This is a 2.0 inch TFT LCD expansion board. This display has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller.It leads out the pins of the TFT and breakout pins pitch is 2.54mm, so the secondary development is less difficult. With GPRS module, you can design your Arduino phone. With NFC reader module, you can create access control systems with the photos show. With voltage and current sensor, you can make oscilloscope. Can use it directly to display characters, graphics and BMP format images. Compatibility: Because the logic level is 3.3V, it is compatible with 3.3V Arduino board, you generally need to add a level conversion circuit if you use a 5V Arduino Board (Arduino UNO R3 / Arduino Mega2560 / Arduino Leonardo). Arduino library: UTFT Driver IC: S6D1121 Touch screen type: resistive touchscreen. Touch Pen: length is 9cm; Resolution: 240X320, 16-bit (262,000) color Display size: 2.0 inch; Operating voltage: 3.3V; Logic level: 3.3V; Operating current: the maximum is 150mA LED pin can connect to external backlight control circuit to control the brightness of backlight. You can connect it to GND to turn on the backlight all day. Very suitable for digital photo frame, oscilloscope, function generator, detection system monitor
