ESP32-S3-LCD-3.16 - development board with ESP32-S3 module and 3.16" display

Description

ESP32-S3 3.16inch Display is a modern and high-performance development board designed for HMI, IoT, and data visualization applications. It is powered by the advanced ESP32-S3R8 microcontroller featuring a 32-bit dual-core Xtensa LX7 processor running at up to 240 MHz, providing excellent computing power and reliable operation. The module supports Wi-Fi 2.4GHz (802.11 b/g/n) and Bluetooth 5 (BLE), making it ideal for wireless communication and integration with modern smart devices. The board includes a 3.16-inch color LCD display with a resolution of 320×820 pixels and 64K colors, driven by the ST7701 controller, ensuring smooth operation of graphical interfaces such as LVGL. A built-in RTC (PCF85063) provides accurate timekeeping, while the QMI8658 sensor offers 6-axis IMU functionality (accelerometer + gyroscope), enabling motion detection, gesture recognition, and step counting. The board also features UART, I2C, and USB connectors (MX1.25 and SH1.0), allowing easy expansion with additional modules. In addition, the module includes a micro SD card slot for reading and writing data such as images or configuration files. The integrated 3.7V lithium battery connector with a charging function and USB Type-C port ensure convenient power supply and programming.

The board includes a power switch for quick system control and BOOT and RESET buttons to simplify software development and testing. With 16MB Flash and 8MB PSRAM, the module efficiently handles complex graphical interfaces, AI computations, and real-time data processing. High-quality components, a compact design, and broad connectivity options make it an excellent solution for embedded systems, smart displays, control devices, and AIoT projects. The ESP32-S3 3.16inch Display combines performance, flexibility, and functionality, making it a perfect platform for learning, prototyping, and developing advanced applications.
