This ESP32-S3 development board is built around the Xtensa 32-bit LX7 dual-core processor, capable of running at speeds up to 240MHz, making it ideal for a wide range of projects. With support for 2.4GHz Wi-Fi (802.11 b/g/n) Bluetooth 5 (LE), and an onboard antenna, this board provides strong wireless communication for your projects.
The board comes with 512KB SRAM, 384KB ROM, 16MB of Flash, and 8MB of PSRAM, offering ample memory and storage using an SD card for trickier projects. It also has a 4.3" capacitive touch display with an 800 x 480 resolution, capable of displaying 65K colours and supporting up to 5-point multi-touch control via an I2C interface. This display is ideal for creating interactive GUI programs, such as those built with LVGL, and has a wide 160° viewing angle for an improved watching experience.
Designed for quick development of Human-Machine Interfaces (HMI) and other ESP32-S3 applications, this board also includes various peripheral connectors, allowing you to easily integrate additional components and expand functionality. Whether you're working on IoT projects, smart devices, or interactive displays, this development board offers the tools to help you create many different projects.
