Arduino Uno R4
₦40,000 · In stock
The Arduino Uno R4 is a significant upgrade to the classic Uno line, built around a 32-bit Renesas RA4M1 (Arm Cortex-M4) microcontroller running at 48 MHz, with 256 kB Flash and 32 kB SRAM—a major leap over the R3's 8-bit architecture. It retains the classic Uno form factor, pinout, and 5V operating voltage for full shield compatibility, while adding a USB-C connector, a 12-bit DAC, a real-time clock (RTC), CAN bus support, and 14-bit ADC resolution. The **Uno R4 WiFi** variant also includes an ESP32-S3 module for Wi-Fi and Bluetooth connectivity, a 12x8 red LED matrix, and a Qwiic I2C connector for solderless prototyping, making it ideal for IoT and wireless projects.
