Development Board Battery Assembly Guide

info

When disassembling, pay special attention to the cable area. The connection in this part is fragile. Pulling, twisting, or applying excessive force can easily cause breakage and affect device operation. Before disassembly, understand the importance of cable protection. During disassembly, move slowly and gently. When separating the enclosure from the motherboard, observe the location and routing of the cable connections. Support the motherboard or cable to keep it in a natural, tension-free state to avoid forced dismantling.

Usage Limitations and Multiplexing Notes

• GPIO14 and GPIO15 are the shared onboard I2C bus. External devices must avoid address conflicts with existing devices and ensure bus voltage level compatibility.
• GPIO19 and GPIO20 are the native USB data lines; multiplexing them will affect USB downloading, communication, and debugging.
• GPIO43 and GPIO44 are UART0, typically used for logging and debugging. Please confirm your debugging requirements before occupying them.
• GPIO0 is the boot configuration pin and is also connected to the BOOT button. It should not be used as a fixed pin for general peripherals.
• Display, touch, audio, TF, IMU, and RTC use the GPIOs listed in the table. Before starting secondary development, please confirm whether the corresponding functions need to be disabled or used in conjunction with the existing drivers.

Button Description

Button	Function
BOOT	Long-press and power on to enter download mode, suitable for recovery when the program is abnormal or USB/GPIO is occupied. During normal operation, the button state can be read via GPIO0; a low level indicates it is pressed.
PWR	Long-press for about 6 seconds to power off while the device is on. Single-click to power on when the device is off (charging is still possible while off). During normal operation, the button state can be read via GPIO10; a high level indicates it is pressed. Long-pressing for more than about 6 seconds will trigger a shutdown.

Development Methods

The ESP32-S3-Touch-AMOLED-2.06 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.
