- Power Connection: Connect the module to a 5V power source using the Type-C USB cable. Alternatively, if using a battery, connect it to the 1.25mm 2-pin BAT connector.
- Driver Installation: Ensure you have the necessary USB-to-serial drivers installed on your computer for the ESP32-C3. These are typically included with the ESP-IDF or Arduino IDE ESP32 board packages.
- IDE Setup: Install the Arduino IDE or ESP-IDF (Espressif IoT Development Framework) on your computer. Configure the IDE to support ESP32-C3 boards.
- Connect to Computer: Plug the Type-C USB cable into the module and your computer.
Operating Instructions
The ESP32 Round Display Module operates by executing code uploaded to its ESP32-C3 microcontroller. Here's how to get started:
-
Upload Code:
You can upload your custom code to the screen via an Integrated Development Environment (IDE) like Arduino IDE or using the ESP32 Download Tool.
Figure 3: Code Upload Process. Demonstrates using an IDE (like Arduino) or the ESP32 Download Tool to program the module. - Arduino IDE: Select the correct ESP32-C3 board and COM port. Hold down the "Boot" button, press "Reset", then release "Boot" to enter upload mode. Upload your sketch.
- ESP32 Download Tool: Use this tool for flashing pre-compiled firmware (.bin files). Configure SPIFlash settings (e.g., SPI Speed, SPI Mode) and select the correct COM port and baud rate.
- Display Interaction (for touch versions): If your module includes capacitive touch, your uploaded code will define how touch inputs are processed. This typically involves detecting taps, swipes, or presses to navigate menus or trigger actions.
-
Display Examples: The module is capable of displaying various types of information, from simple text and graphics to complex watch faces and sensor data.

Maintenance
- Keep the module clean and free from dust and moisture.
- Avoid exposing the display to direct sunlight or extreme temperatures.
- Handle with care to prevent physical damage to the screen or PCB.
- Regularly check for firmware updates from the manufacturer or community to improve performance and add features.
Troubleshooting
- Display not turning on:
-
- Ensure the Type-C cable is securely connected and providing 5V power.
- If using a battery, check its charge and connection to the 1.25mm 2-pin BAT connector.
- Verify that the correct firmware has been uploaded to the ESP32-C3 module.
- Code upload fails:
-
- Check if the correct COM port is selected in your IDE/tool.
- Ensure the necessary USB-to-serial drivers are installed.
- Make sure the module is in bootloader mode (hold "Boot" button, press "Reset", then release "Boot").
- Try a different Type-C USB cable.
- Touchscreen unresponsive (for touch versions):
-
- Verify that your uploaded code includes touch screen initialization and handling.
- Check for any physical damage to the touch surface.
- Ensure the touch controller is correctly configured in your software.
User Tips
- Community Resources: Explore online forums and communities for ESP32 and display modules. Many users share code examples and troubleshooting tips.
- Power Management: When running on battery, optimize your code for low power consumption to extend battery life.
- Experiment with Libraries: Utilize existing display and ESP32 libraries (e.g., LVGL, TFT_eSPI) to simplify development and create rich user interfaces.
