ESP32-S3-Touch-LCD-1.83 - ESP32-S3 development board with 1.83" IPS touch display 240x284px + battery - Waveshare 32790

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, delivering 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, combined with the included 3.7 V lithium battery, enables the development of self-powered prototypes and testing of devices in mobile operating conditions without the need for a permanent external power source.
