ESP32-S3-Touch-LCD-1.83-EN - ESP32-S3 development board with 1.83" IPS touch display 240x284px - Waveshare 32791

Description

Development board based on the ESP32-S3 microcontroller, designed for prototyping and integration of smart devices, including IoT applications, interactive systems, and voice-based solutions. The integrated IPS touch display with a diagonal size of 1.83 inch and a resolution of 240 x 284 enables the design of user interfaces without the need for external display modules.

The ESP32-S3 integrates a dual-core Xtensa LX7 processor with a clock frequency of up to 240 MHz, providing high computing performance for graphics processing, audio handling, and wireless communication. Support for 2.4 GHz WiFi and Bluetooth 5 LE enables modern wireless connectivity, while the onboard antenna simplifies end-device design. The board also integrates an audio codec, dual microphone array, speaker, 6-axis IMU, and an RTC chip, allowing advanced multimedia and sensing functions to be implemented in a compact form factor.

The availability of GPIO pins and I2C, UART, and USB interfaces enables project expansion with external modules and seamless integration into custom test and application environments.
