Using this Pimoroni screen kit is easy. First, connect the driver board to a 5V power source with at least 780mA through a micro USB cable or a power supply. If you're using it with a Raspberry Pi, make sure the power supply can handle the combined power needs as it'll get close to 2 Amps. Once powered, use the included cable to connect the screen to your device with HDMI output. You can control the display and navigate the menu using the provided keypad, or you can use your own buttons as the pins on the board are accessible. For maintenance, keep the screen clean by using a soft, dry cloth. Avoid using harsh chemicals or abrasive materials. Store it in a dry and cool place when not in use. When using it for projects like arcade cabinets, make sure it's installed securely to prevent any damage.
