Product Features

This product is a microcontroller development board that supports 2.4GHz Wi-Fi and Bluetooth BLE 5. It integrates large-capacity Flash and PSRAM, has an onboard 1.47-inch LCD screen, can smoothly run GUI interface programs such as LVGL, and combines multiple peripheral interfaces to quickly develop HMI applications for 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 (802.11 b/g/n) and Bluetooth 5 (LE), onboard antenna
• Onboard 512KB SRAM, 384KB ROM, 8MB PSRAM and 16MB Flash
• Onboard 1.47-inch LCD screen, 172×320 resolution, 262K colors
• Lead out most GPIOs and integrate full-speed USB serial port
• Onboard QMI8658 six-axis inertial measurement unit (3-axis acceleration, 3-axis gyroscope) can detect device deflection status, step counting and other functions
• Onboard RGB colored lamp beads, combined with transparent acrylic interlayer, can achieve cool lighting effects
• Onboard Micro SD card slot, can be connected to an external SD card to store pictures or files
• Onboard battery charging management module allows access to batteries to power the device
• Supports flexible clock, multiple power modes and other accurate control to achieve multi-scenario low power consumption mode
