Elecrow 3.5 Inch ESP32-S3 Display with 320x480 Capacitive IPS Touch Panel | With Speaker/Mic/BAT Interface | Supports AI Voice Chat

This 3.5-inch ESP32-S3 development board integrates display, touch, voice, and wireless communication, specifically designed for intelligent interaction and IoT applications. It utilizes a dual-core ESP32-S3 processor with a clock speed of up to 240 MHz, 8 MB of PSRAM, and 16 MB of Flash memory. It supports 2.4GHz Wi-Fi and Bluetooth 5.0, providing ample computing power for complex human-machine interfaces and AI algorithms.

The screen is a 3.5-inch IPS full-view color display with a resolution of 320×480 and 65K colors, offering vibrant colors and a wide viewing angle. The capacitive touchscreen ensures high sensitivity and a smooth human-machine interaction experience. An onboard high-sensitivity microphone and speaker interface (with a speaker included) enable voice capture and playback, supporting the "Xiao Zhi AI" voice chat function, simplifying voice interaction development.

The module integrates a Type-C interface (supporting one-click download), a TF card slot, and a lithium battery charging management circuit (supporting external 3.7V lithium batteries), facilitating the development of portable devices. It offers multiple expansion interfaces such as SPI, IIC, and UART, facilitating connection to various sensors and peripherals. The product has undergone aging tests and multiple inspections, supports a wide operating temperature range of -30~80℃, and, with abundant sample programs and underlying driver technology support, is an ideal choice for smart home control systems, AI voice assistants, and portable smart terminals.
