A new board joins the Arduino family, and it’s the most powerful ever designed for makers, engineers and creators: the GIGA R1 WiFi! Bridging you from great fun to amazing performance, it opens the door to infinite possibilities in robotics, IoT, music, computer vision, digital fabrication, and any kind of projects involving machines, interfaces, and real-time processing - in the same form factor as the popular Mega and Due boards.

The Arduino GIGA R1 WiFi is designed for ambitious makers who want to step up their game. It levels the playing field for gamers, artists, sound designers and anyone coming to the tech world with big ideas on a budget – because it packs advanced features into an accessible component, with the same form factor as our popular Mega and Due.

You can also find a case for the Giga here

Let’s break down all the powerful features of this board:

Microcontroller (STM32H747XI)

This dual-core 32-bit microcontroller allows you to have two brains talking to each other (a Cortex®-M7 at 480 MHz and a Cortex®-M4 at 240 MHz) you can even run micropython in one and Arduino in the other.

It’s “two brains in one” thanks to the dual-core microcontroller (Cortex®-M7 core at 480 MHz and Cortex®-M4 at 240 MHz) which allows you to run two Arduino programs simultaneously – or, why not run an Arduino program and a MicroPython? With this architecture, you can separate higher-level logic such as displays, interfaces, and networking from time-critical tasks such as motor control.

Wireless communication (Murata 1DX)

Whether you prefer Wi-Fi® or Bluetooth®, the GIGA R1 WiFi got you covered. You can even quickly connect to the Arduino IoT Cloud and keep track of your project remotely. And if you are concerned about the security of the communication, the ATECC608A keeps everything under control.

Hardware ports and communication

Following the legacy of the Arduino Mega and the Arduino Due, the GIGA R1 WiFi has 4 UARTs (hardware serial ports), 3 I2C ports (1 more than its predecessors), 2 SPI ports (1 more than its predecessors), 1 FDCAN.

GPIOs and extra pins

We wanted to keep the same form factor of the Mega and the Due, so you can easily adapt your custom-made shields to the GIGA R1 WiFi (remember this board works at 3.3V though!) and we added extra headers to access extra pins, leaving the total count to 76 GPIO pins, and the best part, you can access them from underneath, so keep your project as it is and just think on how to expand it. Also, we added two new pins: a VRTC so you can connect a battery to keep the RTC running while the board is off and an OFF pin so you can shut down the board.


The GIGA R1 WiFi has extra connectors on board which will facilitate the creation of your project without any extra hardware. This board has:

  • USB-A connector suitable for hosting USB sticks, other mass storage devices and HID devices such as keyboards or mice
  • 3.5mm input-output jack connected to DAC0, DAC1 and A7
  • USB-C® to power and program the board, as well as simulate an HID device such as a mouse or keyboard
  • Jtag connector, 2x5 1.27mm
  • 20-pin Arducam camera connector (camera available separately)

Higher voltage support

Compared with its predecessors that support up to 12 volts, the GIGA R1 WiFi can handle a range of 6 to 24 volts.

Package Contents

  • 1x Arduino GIGA R1 WiFi
  • 1x Clear frame case
  • 1x Mini u.FL Antenna



    • Do I need an external antenna? Is it included with the product? Yes and yes, this board has no on board antenna however a u.FL antenna is provided in the box.

    • Which Arducam models are compatible with the on board camera connector? The camera adapter (J6 header) is a 20-pin adapter for Arducam cameras such as OV7675 and OV7670. For more information on how to use the camera visit the GIGA R1 WiFi Camera guide.

    • What is the difference between the Portenta H7 and the GIGA R1 WiFi?

      The difference between these two products are:

      • The GIGA R1 WiFi uses the USB-C® to power and program the board, as well as simulate an HID device such as mouse or keyboard. In the case of the Portenta H7, the USB-C® can also be used as DisplayPort out, USB Hub or to deliver power to OTG connected devices.

      • The GIGA R1 WiFi exposes all the possibilities of the STM32H7 in a more accessible way using 2.54 mm pin headers making it a more suitable option for prototyping whereas the Portenta H7 is suitable for mass production since it uses high-density connectors to save space.

      • Given its form factor the GIGA R1 WiFi has the space to provide additional services such as a USB-A connector, 3.5mm input-output jack and JTAG connector on board.

    • Can I use my previous Arduino UNO, Arduino Mega or Arduino Due shields with the GIGA R1 WiFi? Yes, mechanically the shields are compatible however take into account that the GIGA R1 WiFi operates at 3.3V, so we recommend double-checking the tech specs of the shield to make sure it works at this voltage.

    • What is the difference between the two USB connectors? The GIGA R1 WiFi has two USB connectors. The USB-C® connector (USB0), next to the reset button and the u.FL antenna connector, is used for programming, serial communication and 5V power. The USB-A connector (USB1), next to the 3.5mm jack connector, is used as a USB host (not a programming port).
