This 2.4-inch TFT LCD shield adds vivid graphics and touch interaction to Arduino projects. Featuring a bright 240x320 pixel display, a 4-wire resistive touchscreen, and an onboard microSD slot, it is ideal for GUI dashboards, sensor visualization, and interactive control panels. The shield is designed to plug directly into an Arduino Uno or Mega, providing a seamless hardware integration without the need for complex wiring.
