Arduino Portenta H7 Lite - ABX00046

Description

Arduino Portenta H7 Lite Connected is a module with a dual-core STM32H747XI microcontroller with a CortexM7 + M4 core equipped with 2 MB flash memory, 1 kB RAM and allows clock speeds up to 480 MHz. The board has a built-in WiFi module and Bluetooth 5.1

The main H7 processor is the dual-core STM32H747, including Cortex M7 operating at 480 MHz and Cortex M4 operating at 240 MHz. The two cores communicate via a remote procedure call mechanism that allows smooth function calls on the second processor. Both processors share all peripheral devices in the system and can operate using:

• Arduino using the Arm Mbed operating system
• Native Mbed applications
• MicroPython/JavaScript via the interpreter
• TensorFlow Lite

Built-in wireless module allows you to simultaneously manage WiFi and Bluetooth connectivity. The WiFi interface can be operated as an access point, as a station or as a simultaneous AP / STA in two modes and can support transfer speeds up to 65 Mb / s. The Bluetooth interface supports Bluetooth Classic and BLE. It is also possible to provide a variety of different wired interfaces, such as UART, SPI, Ethernet or I2C, both through some MKR style connectors and through a new pair of 80-pin Arduino industrial connectors.

Portenta H7 has the ability to connect an external monitor to build its own dedicated computer with a user interface. This is possible thanks to the built-in GPU chip of the STM32H747 processor, Chrome-ART Accelerator. In addition to the graphics processor, the system includes a dedicated JPEG encoder and decoder.

The board has two 14-pin connectors equipped with GPIO, SPI, I2C, PWM, USART, DAC and ADC and two high-density 80-pin connectors with all system pins.

The kit can easily run processes created using TensorFlow Lite, where one of the cores is used to calculate computer vision algorithms on the fly, while the other can perform low-level operations, such as engine control or acting as a user interface. Thanks to such large possibilities of the board, it will be used in such areas as high-class industrial machines, laboratory equipment, computer vision, PLC controllers, user interfaces, robotics controller, key devices, a dedicated desktop computer or quick startup calculations (ms).
