## Description

The ESP32-S3 development board with 1.47 inch LCD display is ideal for IoT prototypes and compact graphical interfaces, offering a dual core processor up to 240 MHz, WiFi and Bluetooth 5 connectivity, ST7789 screen with fluid display and Micro SD slot for storage, fast programming via USB and Arduino IDE and ESP-IDF compatibility.
ESP32-S3 development board from Waveshare with 1.47 inch LCD screen, RGB LED, WiFi and Bluetooth 5 compatible with Arduino IDE.
It is equipped with a dual-core Xtensa LX7 processor operating at a frequency of up to 240 MHz, which provides the computational power necessary for developing complex and interactive applications.
A distinctive element is the 1.47-inch LCD screen controlled by the ST7789 chip which allows the implementation of fluid graphic interfaces.
Connectivity is provided by WiFi 802.11 b/g/n (2.4GHz) and Bluetooth 5, offering a wide range of options for communication and integration into IoT systems. The Micro SD slot allows for storing files or images.
Thanks to the extensive software support, developers have access to the Arduino platform and ESP-IDF, which facilitates the development of custom applications and complex functionalities.
It features an integrated RGB LED under the display, with light diffusion through the acrylic plate, for pleasant optical effects.
