Freenove Control Board V5 for Arduino UNO R4 WiFi Mini with ESP32-S3 LED Matrix

Meet the Freenove Control Board V5 for Arduino UNO R4 WiFi Mini with ESP32-S3 LED Matrix — a powerful, ready-to-build microcontroller kit designed for ambitious Arduino projects. This latest board packs a 32-bit Renesas RA4M1 ARM Cortex-M4 microcontroller, delivering solid processing power, generous memory, and a streamlined path from idea to code.

Key differences: the V5 WiFi version includes an onboard ESP32-S3 module and a 12x8 red LED matrix for expressive visual projects, while the V5 Mini does not. The board is fully compatible with Blue Rev4, though some code and libraries may not work with Blue Rev3. A detailed tutorial and complete example code are provided for quick start, with downloadable resources available before you purchase.

Install and go — simply connect the board to your computer with a USB cable to program it. Freenove offers free technical support to help with any questions or problems you encounter along the way.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.

Benefits & Tips

• Leverage the 32‑bit ARM Cortex‑M4 core for faster sketches, smoother peripherals, and more reliable real‑time performance in projects ranging from robotics to sensor networks.
• Use the V5 WiFi version for ESP32‑S3 powered features and LED matrix demonstrations, or opt for the V5 Mini when you don’t need onboard Wi‑Fi or the LED matrix. This makes it easier to tailor your build to your needs.
• Take advantage of 14 digital I/O pins, 6 analog inputs, DAC, and multiple communication interfaces (UART, I2C, SPI, CAN) to connect sensors, displays, and modules with confidence.
