ESP32-S3-Touch-AMOLED-1.64

Version Compatibility Note: V1 and V2 example programs are not interchangeable. Please download the corresponding example program based on the PCB version.

The version can be identified by the silkscreen location on the PCB:

• V1: Version silkscreen is located at the top of the PCB.
• V2: Version silkscreen is located on the right side of the PCB, near the pin headers.

Key differences in V2 compared to V1:

• Battery constant current charging current set to 500 mA.
• LCD_CS and IMU_INT1 pins are swapped: V1 uses LCD_CS = GPIO9, IMU_INT1 = GPIO46; V2 uses LCD_CS = GPIO46, IMU_INT1 = GPIO9.
• QMI8658 interrupt pin connected to ESP32 GPIO via resistor, with new IMU_INT2 = GPIO17.
• BOOT button circuit now includes an RC circuit.
• Added reverse polarity protection circuit for the Lithium battery.
• Added TP_INT = GPIO18, TP_RESET, and LCD_TE = GPIO45 pins.

The ESP32-S3-Touch-AMOLED-1.64 is a low-cost, high-performance microcontroller development board designed by Waveshare. It is equipped with an ESP32-S3R8 dual-core LX7 processor (240 MHz), supports 2.4 GHz Wi-Fi and Bluetooth 5 (LE), and features 512KB SRAM and 384KB ROM, with stacked 8MB PSRAM and 16MB Flash. The board includes a 1.64inch AMOLED capacitive touch display (280×456) with 16.7M color support, along with a 6-axis IMU, TF card slot, and Lithium battery charging functionality, making it ideal for rapid prototyping and embedded HMI applications.

Development Methods

The ESP32-S3-Touch-AMOLED-1.64 supports both the Arduino IDE and ESP-IDF development frameworks, giving developers flexible options. You can choose the development tool that best suits your project needs and personal preferences.

Arduino is generally easier to get started with and more beginner-friendly for hobbyists. ESP-IDF offers a more complete development toolchain and finer-grained system control, making it suitable for complex projects or applications with higher performance requirements.

• 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 example programs 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 example programs for reference.
