External power

The mains supply powers the V2M‑Juno motherboard using the on‑board connector, and an external power supply unit and connector cable that Arm supplies with the Juno Development Platform.

The external power supply unit converts mains power to 12V DC. This unit connects to the 12V DC connector on the rear panel of the case. The unit accepts mains power in the range 100‑240V AC.


You must only use the external power supply unit that Arm supplies to power the board.

On‑board regulators supply power to the V2M‑Juno motherboard power domains and to the power domains of the Juno Arm® Development Platform SoC.

Power LEDs indicate that power domains are active:

5V5V domain powered.
3V33V3 domain powered.
SB_5VStandby 5V domain powered.
