Why Choose the Arduino UNO R4 WiFi?
- Massive Performance Upgrade: The 32-bit Arm Cortex-M4 processor at 48 MHz delivers up to 12x more computational power than the classic UNO R3's ATmega328P, with 256 KB flash and 32 KB SRAM.
- Built-in Wi-Fi & Bluetooth: The onboard ESP32-S3 module enables IoT projects out of the box - connect to cloud platforms like Arduino Cloud, Blynk, or MQTT brokers without additional shields.
- 12x8 LED Matrix Display: Create scrolling text, animations, visualizations, and real-time data displays directly on the board - no external display needed for quick prototyping.
- 14-bit ADC Resolution: Read analog sensors with significantly greater precision than the 10-bit ADC on UNO R3, ideal for scientific instruments and precision measurement projects.
- Built-in 12-bit DAC: Generate true analog output signals for audio projects, waveform generation, and analog control systems without external DAC modules.
- CAN Bus Support: Native CAN bus transceiver built into the board for automotive, industrial automation, and robotics communication protocols.
- Onboard Op-Amp: Built-in operational amplifier for signal conditioning and amplification directly on the board.
- USB-C Connector: Modern, reversible USB-C for programming and power - more durable and universally compatible.
- Full Backward Compatibility: Same UNO form factor, 5V logic, and pin layout - your existing shields, sensors, and code work seamlessly.
- 100% Authentic Arduino: Sourced directly from authorized Arduino distributors. Genuine product with full manufacturer backing.
- Fast 1-5 days shipping: Ships from our Bengaluru warehouse to most locations across India. Same-day delivery available in Bengaluru.
- Expert Technical Support: Our engineering team provides hands-on guidance for your projects via email and WhatsApp.
