Description
The Arduino Giga R1 WiFi brings the power of the STM32H7 to the same form factor as the popular Mega and Due, being the first Mega board to include onboard Wi-Fi and Bluetooth connectivity.
The board provides 76 digital inputs/outputs (12 with PWM capability), 14 analog inputs and 2 analog outputs (DAC) all easily accessible via pin headers. The STM32 microprocessor with dual-core Cortex-M7 and Cortex-M4, together with onboard memory and audio jack enables you to perform machine learning and signal processing on the edge.
This dual core 32-bits microcontroller allows you have two brain 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.
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 4x UARTs (hardware serial ports), 3x I²C ports (1 more than its predecessors), 2x SPI ports (1 more than its predecessors), 1x FDCAN.
GPIOs and extra pins
By keeping the same form factor of the Mega and the Due, you can easily adapt your custom made shields to the Giga R1 WiFi (remember this board works at 3.3 V though!). Also, additional headers have been added so that the total number of GPIO pins is now 76, and two new pins have been added: 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.
Connectors
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 keyboard or mouse.
- 3.5 mm 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 mouse or keyboard.
- Jtag connector, 2x5 1.27 mm.
- 20-pin Arducam camera connector.
Higher voltage support: In comparison with its predecessors that support up to 12 V, the Giga R1 WiFi can handle a range of 6 to 24 V.
