Power Supply - Arduino Nano Matter Product Reference Manual

4.3 Power Supply

The Nano Matter can be powered through one of the following interfaces:
Onboard USB-C® port: 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 IN5V pin or the VIN pin of the Nano-styled
header connector. For the VIN pin, ensure the VIN jumper is shorted to enable the power supply.
A detailed figure below illustrates the power options available on the Nano Matter and the main system power
architecture.
Low-Power Tip: For power efficiency, safely cut the LED jumper and connect an external +3.3 VDC power
supply to the board's 3V3 pin. This configuration does not power the board's USB bridge.
Safety Note: Disconnect power before board modifications. Avoid short-circuiting. Refer to the full guide for
more safety tips.
