The control board’s power nodes are accessible in several areas on the board. If you power additional devices from VSW, then they will be powered whenever the control board’s power is in ON, and they will receive whatever voltage the batteries are outputting. If you power them from VREG, they will get 5 V power whenever the batteries are installed and the power is on (but they cannot be powered from USB). If you power them from a 5V pin, then they will receive 5V power whenever the control board’s logic components are powered. If you power them from 3V3, they will receive 3.3V power whenever the control board’s logic components are powered. For more information about these power nodes and how much current they can provide, see Section d'[[alimentation]].

It is also possible to add your own power switch to control power to the Romi 32U4 Control Board, as described in Section 3.5.
