Arduino Uno Wi-Fi V2

Quick Answer: The Arduino Uno Wi-Fi V2 Development Board keeps the familiar Uno form factor and ATmega4809 microcontroller while adding an onboard NINA-W102 Wi-Fi and Bluetooth module, an ATECC608 crypto authentication chip, and an LSM6DS3TR IMU, making it a strong choice for IoT, robotics, and wireless sensor coursework.

Description

The Arduino Uno Wi-Fi V2 is built around the ATmega4809 microcontroller running at 16 MHz with 5V logic, 48 KB of flash memory, 6 KB of SRAM, and 256 bytes of EEPROM. It keeps the standard Uno form factor with 14 digital I/O pins (5 of them PWM-capable) and 6 analog input pins, so existing Uno shields and wiring diagrams remain compatible. What sets this board apart is its onboard NINA-W102 module for Wi-Fi and Bluetooth connectivity, letting students build connected IoT projects directly from the board without an external shield. An ATECC608 crypto authentication chip adds hardware-level security for cloud and IoT applications, while the onboard LSM6DS3TR IMU provides a 3-axis accelerometer and gyroscope for motion-sensing projects. The board is programmed through the standard Arduino IDE and connects via USB, Wi-Fi, or Bluetooth, making it well suited for IoT projects, STEM education, robotics, automation, and wireless sensor work.

Specifications

Compatibility & Safety Note

• Keeps the standard Uno form factor and pinout, so most Uno-compatible shields and accessories remain usable.
• Program via the Arduino IDE over USB; Wi-Fi and Bluetooth connections require the appropriate board definitions and libraries.
• Operate at the board’s rated 5V logic level; avoid connecting sensors or shields requiring different voltage without proper level shifting.
• Handle the board by its edges and avoid touching the NINA-W102 module or ATECC608 chip directly to prevent static damage.
• Keep the board away from moisture and conductive surfaces during wireless-connected experiments.
• Supervise students during IoT and wireless connectivity exercises, particularly when boards are connected to school networks.
