Using this HDMI connector is easy. First, make sure your CrowPi and Raspberry Pi 4B are powered off. Then, plug one end of the HDMI connector into the HDMI port of the Raspberry Pi 4B and the other end into the corresponding port on the CrowPi. Power on your devices, and you're good to go. When handling the connector, be gentle to avoid bending the pins. Keep it away from moisture and dust. If it gets dirty, you can use a dry, soft cloth to clean it. Don't use any liquid cleaners as they may damage the connector.
