Product Description
Variant: ESP32-S3-Touch-LCD-3.5B-C.
The ESP32-S3 3.5inch Capacitive Touch Display Development Board Type B combines a touch-sensitive display with wireless connectivity, audio processing and motion sensing. This version includes a case and an OV5640 camera. It supports development of connected user interfaces and applications involving speech interaction and image capture. A microphone, audio codec, real-time clock and power management circuitry are integrated on the board.
Peripherals connect through I2C, UART, USB and exposed GPIO connections. A microSD card slot provides storage for logged data or media. Software development is supported through ESP-IDF and Arduino IDE, while a rechargeable lithium battery connection enables battery-powered designs.
