Arduino GIGA R1 WiFi Bridges Portenta H7’s Computing Capacity on Mega Form Factor

Arduino GIGA R1 WiFi

The flexibility of upgrading primitive use cases using the existing hardware can reduce the time of delivery and decrease the additional hardware costs. However, the architectural techniques and power requirements might vary in this process of upgradation, but it should be far better than exploring other hardware options for the same application at an advanced level.  GIGA R1 WiFi board, recently launched by Arduino, brings flexibility in the range of use cases with advanced computing capacity in the form factor of the company’s fundamental microcontroller boards; Mega and Due.

Arduino GIGA R1 WiFi board is powered by STMicroelectronics’ dual-core microcontroller STM32H7, with its core Cortex®-M7 at 480 MHz frequency and Cortex®-M4 at 240 MHz frequency. As Portenta H7 boards have the same STM32H7 microcontroller, hence GIGA R1 WiFi could be expected to have the same high computing capacity. Additionally, the core split in the board allows the developers to use the cores separately for two different technological stacks; MicroPython and Arduino IDE. Arduino says, “you can run MicroPython in one and Arduino in the other core.”

Connectivity of Arduino GIGA R1 WiFi

  • USB-A connector for hosting USB sticks and other mass storage devices
  • HID devices such as keyboards or mouse
  • 3.5mm input-output jack connected to DAC0, DAC1, and A7
  • USB-C for powering and programming the board, as well as simulating HID devices
  • Jtag connector, 2×5 1.27mm
  • 20-pin Arducam camera connector


Talking more about the connectivity, the board comes with a Murata WiFi Bluetooth module for wireless communication ranging from short-range simple applications with Bluetooth to longer-range complex applications with WiFi, using a single component on the board. Also, the board can be connected to the Arduino IoT cloud for collaborative team developments along with tracking the progress of an application or project.
