4.5 Power Supply
The figure below shows the power options available on the Arduino Portenta Mod Carrier and illustrates the
Carrier's power architecture.
The Portenta Mid Carrier can be powered through one of these interfaces:
Onboard USB-C® port of the Portenta board: Provides a convenient way to power the board using standard
USB-C® cables and adapters.
External +5 VDC power supply: This can be connected to the IN 5V pin of the carrier's screw terminal block J4;
it can also be connected to the IN 5V pins of the breakout header connector J15.
Reverse polarity protection: IN 5V pins of the carrier's screw terminal block (J4) and breakout header
connector (J15) do not have reverse polarity protection. Double-check the polarity of your power supply
before connecting it to the Carrier to avoid damaging it.
Safety note: Disconnect power before modifying the carrier connections and configurations to avoid short-
circuiting. For more safety tips, refer to the Carrier's user manual.
