4. Setup
4.1 Physical Connection
Connect the display to your host device (Raspberry Pi, Jetson Nano, or PC) using the provided cables and adapters. The display requires both an HDMI connection for video output and a USB-C connection for touch functionality and power supply.
- HDMI Connection: Use the HDMI cable and appropriate adapter (C or B) to connect the display's HDMI port to your host device's HDMI output.
- USB-C Connection (Power & Touch): Connect the USB-A to USB-C cable from a USB port on your host device to the USB-C port on the display. This provides power and enables touch functionality.
- I2C Connection (Optional Touch): For I2C touch, a configuration file is required. Refer to the manufacturer's resources for specific instructions. The USB-C port can still be used for power.
