Description This is a 2.2-inch TFT LCD expansion board, the monitor built-in controller with RAM cache, so almost no work is done by the microcontroller. Module will be the LCD screen pin into 2.54mm pitch pin, secondary development difficult to reduce. feature With GPRS module With NFC read and write modules, you can make access control and photo display system. With the voltage, current sensor, you can create an oscilloscope. BMP format picture, can achieve touch control Driver chip: ILI9225 - Touch screen type: Resistive touch screen - touch pen: length of 9cm - Resolution: 176X220, 16 (262,000) color - Display size: 2.2 inches - Operating voltage: 3.3V - Logic level: 3.3V - Operating current: Max is 150mA - LED pin can be used for external backlight control circuit to control the backlight brightness, you can directly link to GND, has been lit backlight LED - very suitable for the production of digital photo frame, oscilloscope, function generator, detection system display list 1 x module 1 x touch pen
