With 2MB flash and 1MB RAM, it handles demanding applications like real-time audio processing, computer vision, machine learning, and simultaneous wireless communication. WiFi and Bluetooth connectivity come via the Murata 1DX module, while the board offers an impressive 76 GPIO pins, 4 UARTs, 3 I2C ports, 2 SPI ports, CAN FD, a 3.5mm audio jack with DAC output, and an Arducam camera connector for vision projects. Both USB-A host and USB-C device ports enable connecting peripherals like keyboards, mice, or USB drives. Maintaining the Mega/Due form factor ensures compatibility with existing large-format shields while delivering processing power that rivals single-board computers. The dual-core architecture allows running time-critical tasks on the M7 while the M4 handles wireless communication or secondary processing independently. ## Where to Buy - [Arduino Store (US)](https://openhardware.directory/r?to=https%3A%2F%2Fstore-usa.arduino.cc%2Fproducts%2Fgiga-r1-wifi&ref=openhardware.directory&product=arduino-giga-r1-wifi&source=md-export) — $53.00 - [Arduino Store (EU)](https://openhardware.directory/r?to=https%3A%2F%2Fstore.arduino.cc%2Fproducts%2Fgiga-r1-wifi&ref=openhardware.directory&product=arduino-giga-r1-wifi&source=md-export) — €58.47 - [DigiKey](https://openhardware.directory/r?to=https%3A%2F%2Fwww.digikey.com%2Fen%2Fproducts%2Fdetail%2Farduino%2FABX00063%2F18075937&ref=openhardware.directory&product=arduino-giga-r1-wifi&source=md-export) — $62.40 - [Mouser](https://openhardware.directory/r?to=https%3A%2F%2Fwww.mouser.com%2FProductDetail%2FArduino%2FABX00063&ref=openhardware.directory&product=arduino-giga-r1-wifi&source=md-export) — $62.40 - [Amazon US](https://openhardware.directory/r?to=https%3A%2F%2Fwww.amazon.com%2Fdp%2FB0BZ2LN2WJ&ref=openhardware.directory&product=arduino-giga-r1-wifi&source=md-export) — $62.40 - [SparkFun](https://openhardware.directory/r?to=https%3A%2F%2Fwww.sparkfun.com%2Farduino-giga-r1-wifi.html&ref=openhardware.directory&product=arduino-giga-r1-wifi&source=md-export) — $62.40 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fstore.arduino.cc%2Fproducts%2Fgiga-r1-wifi&ref=openhardware.directory&product=arduino-giga-r1-wifi&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.arduino.cc%2Fhardware%2Fgiga-r1-wifi%2F&ref=openhardware.directory&product=arduino-giga-r1-wifi&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.arduino.cc%2Fresources%2Fdatasheets%2FABX00063-datasheet.pdf&ref=openhardware.directory&product=arduino-giga-r1-wifi&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fdocs.arduino.cc%2Fresources%2Fschematics%2FABX00063-schematics.pdf&ref=openhardware.directory&product=arduino-giga-r1-wifi&source=md-export) ## Tags `arduino`, `giga`, `stm32h747`, `dual-core`, `wifi`, `bluetooth`, `audio`, `camera`, `can-bus`, `usb-c` ## Images ![Arduino GIGA R1 WiFi](https://nbg1.your-objectstorage.com/openhardware-directory/entities/arduino-giga-r1-wifi/2ecb6f8841a3.jpg) ![Arduino GIGA R1 WiFi](https://nbg1.your-objectstorage.com/openhardware-directory/entities/arduino-giga-r1-wifi/1c414f6c9c62.jpg) ![Arduino GIGA R1 WiFi](https://nbg1.your-objectstorage.com/openhardware-directory/entities/arduino-giga-r1-wifi/9ebbd10f50f9.jpg) --- [View full device page](https://openhardware.directory/devices/arduino-giga-r1-wifi)
