The ESP32-S3-ePaper-1.54 is an e-Paper AIoT development board, equipped with ESP32-S3 microcontroller, which supports Wi-Fi and BLE dual-mode communication. The onboard 1.54inch e-paper display, features ultra-low power consumption and sunlight readability, suitable for portable devices and long-lasting scenarios. It integrates an RTC chip, SHTC3 temperature and humidity sensor, TF card slot, low-power audio codec chip circuit, and Lithium battery recharge management circuit. It reserves interfaces including USB, UART, I2C, and GPIO for easy functionality expansion and sensor connectivity, providing a flexible and reliable development platform for IoT terminals, electronic tags, portable displays, and other applications.

Note
  • The V2 version will be phased in starting from November 1, 2025. The products labeled V2 on the back, or with V2 silkscreen in the top-left corner of the PCB, is the V2 version. Otherwise, it is the V1 version. Example programs are not interchangeable between different versions.
  • V1 Version: Equipped with ESP32-S3FH4R2, integrated 4MB Flash and 2MB PSRAM.
  • V2 Version: Equipped with ESP32-S3-PICO-1-N8R8, integrated 8MB Flash and 8MB PSRAM; also features optimized whole-board power consumption in sleep mode.

Development Methods​

The ESP32-S3-ePaper-1.54 supports two development frameworks: Arduino IDE and ESP-IDF, offering flexibility for developers. You can choose the appropriate development tool based on project requirements and personal preference.

Both development methods have their own advantages. Developers can choose based on their needs and skill levels. Arduino is simple to learn and quick to start, suitable for beginners and non-professionals. ESP-IDF provides more advanced development tools and stronger control capabilities, suitable for developers with professional backgrounds or higher performance requirements, and is more appropriate for complex project development.

  • Arduino IDE is a convenient, flexible, and easy-to-use open-source electronics prototyping platform. It requires minimal foundational knowledge, allowing for rapid development after a short learning period. Arduino has a huge global user community, providing a vast amount of open-source code, project examples, and tutorials, as well as a rich library ecosystem that encapsulates complex functions, enabling developers to implement various features rapidly. You can refer to the Working with Arduino to complete the initial setup, and the tutorial also provides related demos for reference.

  • ESP-IDF, short for Espressif IoT Development Framework, is a professional development framework launched by Espressif Systems for its ESP series of chips. It is based on C language development and includes compilers, debuggers, flashing tools, etc. It supports development via command line or integrated development environments (such as Visual Studio Code with the Espressif IDF plugin), which provides features like code navigation, project management, and debugging. We recommend using VS Code for development. For the specific configuration process, please refer to the Working with ESP-IDF. The tutorial also provides relevant demos for reference.
