Arduino Uno WiFi Rev2 Wireless Development Board
Arduino Uno WiFi Rev2 board with ATmega4809, integrated Wi-Fi, secure ECC608 chip, onboard IMU sensor, and OTA programming for IoT projects.
The Arduino Uno WiFi Rev2 is a powerful development board that combines the classic Arduino Uno form factor with integrated Wi-Fi connectivity and advanced sensing capabilities. Featuring the new ATmega4809 8-bit microprocessor from Microchip, this board offers enhanced performance for a wide range of IoT (Internet of Things) and embedded projects.
A key upgrade is the onboard IMU (Inertial Measurement Unit), enabling motion and orientation sensing for robotics, drones, and interactive installations. The ECC608 crypto chip accelerator ensures secure Wi-Fi connections, making it suitable for applications requiring encrypted data transmission. The self-contained Wi-Fi module includes a full TCP/IP protocol stack, allowing the board to easily connect to existing networks or function as its own access point.
Programming and Development
Support for OTA (Over-The-Air) programming is a standout feature, permitting wireless updates for both your Arduino sketches and the Wi-Fi module's firmware, streamlining remote deployment and maintenance. The board retains the familiar Uno footprint with 14 digital I/O pins (6 usable as PWM outputs), 6 analogue inputs, a 16 MHz ceramic resonator, USB connection, power jack, ICSP header, and a reset button. It is powered via USB or an external 7–12V source.
