Product Features
This product uses the ESP32-S3R8 chip, supports 2.4GHz Wi-Fi and BLE 5 Bluetooth functions, and has built-in large-capacity Flash and PSRAM. It is equipped with a 3.16-inch high-definition LCD display and can run GUI programs such as LVGL smoothly. It has onboard RTC, IMU, Micro SD card slot and lithium battery charging function, rich peripheral resources, and reserved USB, UART and I2C interfaces, providing flexible expansion capabilities. It is an ideal choice for rapid development of HMI applications based on ESP32-S3.
The main features are：
- Equipped with high-performance Xtensa 32-bit LX7 dual-core processor, with a main frequency of up to 240MHz
- Supports 2.4GHz Wi-Fi and Bluetooth 5 (LE), with internal antenna on board and reserved solder points for external antenna
- Built-in 512KB SRAM and 384KB ROM, stacked with 16MB Flash and 8MB PSRAM
- Onboard 3.16-inch LCD display, 320 × 820 resolution, 64K color, communication interface uses RGB565
- Onboard QMI8658 six-axis inertial measurement unit (3-axis acceleration, 3-axis gyroscope) for motion detection, step counting, etc.
- Onboard PCF85063 RTC chip, reserved SH1.0 battery slot, can easily realize RTC function requirements
- Use a toggle switch to control the power on and off of the system, which is more controllable
- Onboard RST and BOOT side buttons, BOOT supports custom button functions, making development and use more flexible
- Onboard 3.7V MX1.25 lithium battery charging and discharging interface
- Onboard Micro SD card slot, can be connected to an external Micro SD card to store pictures or files
- Lead out UART, I2C SH1.0 4PIN interface and USB MX1.25 4PIN interface
- Onboard USB Type-C interface, which can be used for power supply and download debugging, making it convenient for development and use
