The Arduino Portenta H7 is based on a dual-core STMicroelectronics STM32H747 microcontroller that enables the board to simultaneously run high-level code along with real-time tasks.
The STM32H747 processor’s 480 MHz Arm Cortex-M7 core and 240 MHz Arm Cortex M4 core communicate via a Remote Procedure Call mechanism that allows each processor to call functions on the other processor seamlessly. Both processors share all the in-chip peripherals and can run Arduino sketches on top of the Arm Mbed operating system, native Mbed applications, MicroPython and JavaScript (via an interpreter), and TensorFlow Lite.
The Portenta can run like other embedded microcontroller boards, or as a main processor of an embedded computer, with the STM32H747 processor’s GPU enabling engineers to connect the board to an external monitor.
An onboard Murata Type 1DX wireless module facilitates simultaneous Wi-Fi and Bluetooth Classic and Bluetooth Low Energy connectivity. The Wi-Fi interface can be operated as an access point (AP), station (STA), or dual-mode simultaneous AP/STA, with a transfer rate up to 65 Mbps.
The board supports wired interfaces such as UART, SPI, Ethernet, and I²C, through the MKR-compatible connectors or through two 80-pin high-density connectors, which ensure scalability for a wide range of applications.
