Arduino Portenta H7 Lite Development Board - ABX00045

What It Is

The Arduino Portenta H7 Lite is a dual'core microcontroller board built around the STM32H747XI chip, offering powerful processing for real'time control, edge computing, AI inference, and complex IoT tasks especially in environments where wireless is not needed or practical (no onboard Wi'Fi/Bluetooth).

It is tuned for industrial robotics, automation, mission'critical systems, and on'device machine learning, while maintaining compatibility with the broader Arduino ecosystem and expansion modules.

Key Features Explained

Dual'Core Processing

• STM32H747XI combines two ARMs:

  • Cortex'M7 @ 480MHz for computation'intensive tasks like signal processing, edge AI, and data fusion.

  • Cortex'M4 @ 240MHz for real'timxible task distribution.

   

  Connectivity & Expansion

  • Ethernet PHY (10/100Mbps) available through the expansion port for reliable wired networking.

  • No onboard Wi'Fi or Bluetooth (unlike the Portenta H7 Lite Connected) useful in environments where RF is restricted or not required.

  • MKR'style headers and two 80pin high'density connectors expose extensive peripheral interfaces (UART, SPI, I2C, PWM, ADC, DAC) and allow stacking Portenta shields or specialized modules.

   

  Power & Interfaces

  • USB'C port for programming, power, USB host/device roles, and OTG connectivity.

  • Li'Po battery support built'in charger for single'cell Lithium cells, enabling portabl/strong> provides hardware'based security for authentication and secure key storage.

   

  Software & Development Support

  You can program the Portenta H7 Lite using multiple development environments:

  Arduino IDE familiar C/C++ sketches and libraries Mbed OS real'time OS for complex embedded control MicroPython / JavaScript interpreters fast prototyping TensorFlow Lite deploy machine learning models on the deviceThis makes the board versatile for a wide spectrum of embedded and AI tasks.

   

  Typical Applications
