ESP32-S3 UNO WROOM-1-N8R2 development board with Wi-Fi and Bluetooth LE

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The ESP32-S3 UNO WROOM-1-N8R2 Development Board is a powerful development board based on the Espressif ESP32-S3 WROOM-1-N8R2 module. It features an Arduino UNO compatible form factor, making it easy to use with many Arduino shields and expansion boards. The powerful dual-core processor together with built-in Wi-Fi and Bluetooth Low Energy makes it suitable for IoT, smart home, robotics, data logging, automation and advanced embedded applications.

The ESP32-S3 operates with 3.3 V logic levels and delivers significantly higher performance than a traditional Arduino UNO R3. The microcontroller features a dual-core Xtensa LX7 processor running at up to 240 MHz, 8 MB Flash memory and 2 MB PSRAM, providing plenty of memory for large applications, web servers, graphics and wireless communication.

The board includes a USB Type-C connector for programming and power. An onboard CH340C USB to serial converter provides reliable programming and communication through a standard COM port. Power is supplied through an onboard DC-DC step-down converter followed by a 3.3 V regulator for efficient operation.

In addition to the Arduino UNO compatible headers, the board provides 13 extra GPIO pins for expanded connectivity. It also includes a built-in addressable RGB LED that can be controlled using libraries such as Adafruit NeoPixel or FastLED.

The board is compatible with Arduino IDE, PlatformIO, ESP-IDF and MicroPython. It supports UART, SPI, I2C, I2S, PWM, ADC and interrupts, making it suitable for both beginners and experienced developers.
