Frequently asked questions
Can I connect 5 V sensors directly to the Portenta H7?
No. The I/O pins operate at 3.3 V logic. Use a level shifter for 5 V sensors and modules to avoid damaging the board.
Does it work with the Arduino IDE?
Yes, the Portenta H7 is supported by the Arduino IDE and Arduino Cloud Editor. Most of its pins are accessed through the 80-pin edge connector, so a Portenta breakout or carrier board is usually needed for easy wiring.
