Arduino GIGA R1 WiFi board launches with STM32H7 MCU, up to 76 I/O pins

Arduino GIGA R1 WiFi board brings the STM32H7 dual-core Cortex-M7/M4 microcontroller found in the Portenta H7 boards to the larger Arduino Mega/Due form factor with up to 76 GPIO pins.

As its name implies, the board also comes with a WiFi 4 (and Bluetooth 5.1) module, as well as an audio jack, a USB Type-C port for programming, a USB 2.0 Type-A host port, and extra connectors for a display and a camera.

It’s not a member of the Arduino Pro family and the Arduino GIGA R1 WiFi loses some of the features from the Portenta H7 series with no support for DisplayPort over USB-C, no on-board 10/100M Ethernet PHY, no high-density connectors, no built-in battery support, and the temperature range is not specified.

Still, the new board has plenty of I/Os, WiFi & Bluetooth connectivity, and a powerful microcontroller that makes it suitable for a range of applications such as robotics, IoT, music, computer vision, and projects requiring real-time processing such as motor control.

Just like the Portenta boards, the Arduino GIGA R1 WiFi board can be programmed with the Arduino IDE or MicroPython, and the company says that thanks to the dual-core design two programs can run simultaneously with both cores running Arduino code, or one core running an Arduino sketch and the other a MicroPython script. You’ll find instructions to get started on the documentation website.

The Arduino GIGA R1 WiFi board is available now for $72.82 or 68.70 Euros on the Arduino store.
