Arduino Portenta H7 / ABX00042

TheArduino Portenta H7 / ABX00042 is a high-performance microcontroller based on a dual-core STM32H747 processor, including a 480 MHz Cortex® M7 and a 240 MHz Cortex® M4, which allows you to simultaneously process high-level programming language code (such as processes created using TensorFlow™ to compute computer vision algorithms) and combine this with the execution of low-level tasks in real time (such as motor control). This microcontroller has dual functionality - it can operate as a microcontroller, and when included in a Portenta Carrier board with standard interfaces, it can also operate as a performance microcomputer.

Main areas of application:

• High-performance industrial equipment.
• Laboratory equipment.
• Programmable logic controller
• Computer vision devices.
• Ready-to-use user interfaces.
• Robotics controller.
• Critical devices.
• Dedicated desktop computer.

The two cores of the STM32H747 processor interact through a remote procedure call mechanism that allows you to seamlessly call functions on another processor. Both processor cores share all the built-in peripherals and can work with:

• Original Mbed™ applications
• Arduino sketches on top of the Arm® Mbed™ operating system
• MicroPython / JavaScript via an interpreter
• TensorFlow ™ Lite

The graphics accelerator allows you to connect an external monitor thanks to the built-in STM32H747 Chrom-ART Accelerator™ GPU, which actually creates a separate computer with a user interface from the microcontroller. In addition to the GPU, the chip includes a special JPEG encoder and decoder.

The board contains 2 high-density 80-pin connectors, which is a new standard for such boards. These connectors provide scalability potential for a wide range of applications. The board is also equipped with the following interfaces: UART, SPI, Ethernet, I2C, and a multifunctional USB-C port that can be used to power the board, act as a USB hub, connect a DisplayPort monitor, and supply power to connected OTG devices.

The built-in wireless module allows you to simultaneously manage WiFi and Bluetooth® connectivity. The WiFi interface can operate with a transmission speed of up to 65 Mbps simultaneously in the following modes:

• as an access point
• as a station,
• as an AP / STA

The Bluetooth® interface supports Bluetooth Classic and BLE (Bluetooth Low Energy).
