Compatibility
The Portenta H7 is fully supported in the Arduino IDE and Arduino Pro IDE, as well as MicroPython and professional IDEs like STM32CubeIDE. It is compatible with Portenta family shields (Vision, LoRa, etc.) and many standard Arduino libraries. The board operates at 3.3V logic levels; use level shifters when interfacing with 5V sensors or modules.
Wiring Notes
Always power the board via the USB-C connector or apply 5V to the VIN pin. I/O pins are rated for 3.3V and are not 5V tolerant—directly connecting 5V signals may damage the board. Use the I2C, SPI, or UART pins as labeled; for analog inputs, use A0–A7. The onboard RGB LED is controllable via digital pins.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino Uno shields?
The Portenta H7 uses 3.3V logic and has a different pinout, so Uno shields are not directly compatible. You can use breakout boards or level shifters to connect them, but full shield stacking is not supported.
Can I run TensorFlow Lite on this board?
Yes, the Portenta H7's dual-core processor and ample memory make it well-suited for TensorFlow Lite Micro. Arduino provides libraries and examples for on-device machine learning inference.
What programming environments can I use?
You can program the Portenta H7 using the standard Arduino IDE, Arduino Pro IDE (with advanced debugging), MicroPython, or STM32CubeIDE for low-level development. The board appears as a USB drive for easy firmware upload.
