Description

High-performance development board based on the ESP32-S3R8 chip with a dual-core Xtensa LX7 processor running at up to 240 MHz, integrated with a 3.49-inch IPS color display with a resolution of 172 × 640 pixels and a capacitive touch panel. Supports 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), uses a built-in antenna and allows expansion with an external one via an IPEX1 connector.

On board are: 8 MB PSRAM, 16 MB Flash memory, PCF85063 RTC, 6-axis QMI8658 IMU, dual digital microphone, and ES8311 & ES7210 audio codecs with noise and echo reduction. The microSD slot allows storage expansion, and the 22-pin (2.54 mm) expansion header enables integration with additional modules.

The case A enclosure includes front function buttons (power, BOOT, backlight control) and a battery bay for an 18650 cell, though in this version the battery is not included.

The board supports ESP-IDF and Arduino IDE environments, and enables implementation of offline and online voice recognition functions.
