Getting Started with EE02

Introduction​

The EE02 is a high-performance E-ink screen driver board specifically designed for 13.3-inch electronic paper displays. Powered by the ESP32-S3 chip, it supports Wi-Fi and Bluetooth connectivity, making it an ideal solution for wireless display applications.

Similar to its sibling, the EE04 (designed for smaller screens), the EE02 offers a seamless experience for developers looking to integrate large-format E-ink displays into their IoT projects. It simplifies the driving process and supports the SenseCraft HMI platform for easy content management.

Features​

  • Powerful Controller: Built around the ESP32-S3, offering robust processing power and wireless capabilities.
  • Dedicated for Large Screens: Specifically optimized to drive 13.3-inch E-ink displays with high stability and clarity.
  • Wireless Connectivity: Supports Wi-Fi and Bluetooth 5.0 (LE), enabling remote data updates and cloud integration.
  • Low Power Consumption: Designed for energy efficiency, suitable for battery-powered applications.
  • Easy Integration: Compatible with SenseCraft HMI for drag-and-drop interface design and remote management.
  • Versatile Interfaces: Includes Type-C for power/programming and standard connectors for E-ink screens.

Getting Started with SenseCraft HMI​

This section will guide you through connecting your EE02 to the SenseCraft HMI platform, allowing you to easily update the screen content wirelessly.

Equipment Installation​

Step 1. Connect the Screen and Board Carefully connect the FPC cable of the 13.3-inch E-ink screen to the connector on the EE02 driver board. Ensure the locking mechanism is secure.

Step 2. Power On Connect the EE02 board to a power source (computer or USB adapter) using a USB Type-C cable. Upon powering up, the screen will refresh and display a welcome image.

Step 3. Enter Network Configuration Mode After the welcome image, the screen will automatically refresh to show the Network Configuration interface. This indicates the device is ready to connect to Wi-Fi.

Network Configuration​

Step 4. Configure Wi-Fi via Mobile Phone Use your mobile phone to scan the QR code displayed on the screen (or connect to the hotspot indicated). Follow the prompts on your phone to enter your local Wi-Fi SSID and password to connect the EE02 to the internet.

Step 5. Obtain Pairing Code Once the network configuration is successful, the screen will refresh again and display a unique Pairing Code (or Device ID). You will need this code for the next step.

Platform Binding & Update​

Step 6. Bind Device on SenseCraft HMI Go to the SenseCraft HMI Platform. Log in to your account. Navigate to the device management section and select "Add Device". Enter the Pairing Code displayed on your E-ink screen to bind the device to your account.

Step 7. Create and Push New Interface On the SenseCraft HMI platform, use the editor to create a new interface (e.g., upload an image or design a dashboard).

Step 8. Apply your images Once finished, click "Apply" button at the top right corner, and then select the device you want to receive the image. The EE02 will receive the data and refresh the 13.3-inch screen with your new content.

Step 9. Display on the screen

Finally the EE02 will receive the data and refresh the 13.3-inch screen with your new content.

Troubleshooting​

Q1: The screen does not refresh after powering on.

  • Check if the FPC cable is correctly inserted and locked.
  • Ensure the USB Type-C cable provides sufficient power.
  • Press the Reset button to restart the board.

Q2: Wi-Fi configuration fails.

  • Ensure your Wi-Fi network is 2.4GHz (5GHz is not supported).
  • Check if the Wi-Fi password was entered correctly.
  • Move closer to the router to ensure a strong signal.

Q3: The screen display is blurry or has ghosting.

  • This can happen if the screen hasn't been refreshed for a long time or if the power supply is unstable. Try refreshing the screen again via the HMI platform.
