  • If your display device does not have a USB Type C port, you will need a USB Type C Dock. Please follow these steps:

    a. Connect the USB Type C Dock to the USB Type C port of your LattePanda.
    b. Connect the USB Type C Dock to your TV or monitor by HDMI or DP cable.
    c. Connect the USB Type C PD power adapter to the USB Type C Dock.
  • If your display has a full fuction USB Type C port that supports DP, PD and USB, a single USB Type C cable is sufficient. Please follow these steps:


a. Connect the USB Type C cable to the USB Type C port of your LattePanda.
b. Connect the other end of the USB Type C cable to the display device. 
c. Connect the USB Type C PD power adapter to the display device.

eDP(Embedded DisplayPort)


In most cases, any display devices which have a 30Pin eDP connector and is powered by 3.3V is compatible with LattePanda 3 Delta and don't require additional drivers. The eDP connector of LattePanda 3 Delta has 2 lanes.


Installation Steps

Ensure Correct eDP Cable Installation

To avoid any potential damage to your LattePanda or display device, it's important to ensure that the eDP cable is correctly installed and the display is connected before turning on your LattePanda. Please double-check these connections carefully, as failure to do so may cause a short circuit.

  • Ensure the LattePanda is powered off and disconnected from power supply cable.

Touch Panel

Touchscreen connections can be made using USB, I2C, or Type-C.

  • USB and Type-C connections are simple and convenient, suitable for most PCs and tablets.
  • I2C connection is commonly used in embedded applications, especially for eDP touchscreen screens.

When choosing a touchscreen, it is important to consider the requirements of the device and the intended application scenario in order to choose the appropriate connection method.

The USB connection is a common method for connecting a touchscreen, known for its simplicity, convenience, and wide compatibility. Most personal computers and tablets support USB interfaces, making it suitable for these devices. USB connection typically utilizes the USB HID (Human Interface Device) protocol for communication, enabling basic touchscreen functionality.

The I2C connection is a serial communication protocol commonly used for embedded devices. In the context of touchscreens, the I2C connection is often employed for connecting eDP (Embedded DisplayPort) touchscreen screens. Compared to USB connection, I2C has a lower transmission rate but is more prevalent in embedded applications. Selecting an I2C connection usually requires considering factors such as device power consumption and space limitations.

The Type-C connection is a versatile and comprehensive standard that supports various protocols and functions, including USB, DisplayPort, and Power Delivery. Opting for a Type-C connection is typically suitable for scenarios that demand both data transfer and power charging capabilities simultaneously, such as high-performance tablets and mobile devices.
