Product Description
The ESP32-S3 3.5inch Capacitive Touch Display Development Board Type B combines a graphical user interface with wireless connectivity, audio processing and motion sensing. It supports the development of connected control panels, voice-controlled applications and mobile data acquisition devices. The ESP32-S3-Touch-LCD-3.5B version is supplied without an enclosure or camera module.
External components connect through USB Type-C, the GPIO header and the camera interface. A lithium battery connector with charging management supports battery-powered designs. Software development is supported through ESP-IDF and Arduino IDE, while a microSD slot provides storage for recorded data or media.
