2.8 diagonal color touchscreen TFT 240x320 resolution 18bit (262 000) color our library uses 16 bit color mode ILI9341 (datasheet) controller with built in video RAM buffer STMPE610 touch screen controller High speed SPI display with digital SPI touchscreen driver The display uses digital pins 139. Touchscreen controller requires digital pin 8. microSD pin requires digital #4. That means you can use digital pins 2 3 5 6 7 and analog 05. Pin 4 is available if not using the microSD Works with any classic Arduino '328. Solder closed three jumpers to use the ICSP header for use with Leonardo or Mega Onboard 3.3V @ 300mA LDO regulator current draw depends on usage but is about 100mA for the display and touchscreen 4 white LED backlight. On by default but you can connect the transistor to a digital pin for backlight control 4wire resistive touchscreen attached to STMPE610 controller
