Learn about the power supply requirements for the Portenta Machine Control.

Upload and run sketches

Connecting a micro USB cable provides sufficient power to upload and run a sketch on the Portenta H7 microcontroller. However, most Portenta Machine Control functionality requires an external power supply, and will not be available in this configuration.

Digital programmable

  1. Find the PROGRAMMABLE DIGITAL I/O pins.
  2. Connect a 24 V power supply to the 24V IN and GND pins.

Portenta Machine Control. The PROGRAMMABLE DIGITAL I/O pins are highlighted.

All other pins

  1. Find the PWR SUPPLY pins.
  2. Connect a 24 V power supply to one of the 24V IN pins.
  3. Connect a 24 V power supply to one of the GND pins.
