External power
The mains supply powers the V2M-Juno r2 motherboard using the on-board connector, an external
power supply unit, and a connector cable that ARM supplies with the V2M-Juno r2 motherboard.
The external power supply unit converts mains power to 12V DC and this connects to the 12V DC
connector on the rear panel of the case. The unit accepts mains power in the range 100-240V AC.
Alternatively, you can connect an ATX power supply unit directly to the board.
On-board regulators supply power to the V2M-Juno r2 motherboard power domains and to the power
domains of the Juno r2 SoC.
Power LEDs indicate the power domains that are active:
5V
5V domain powered.
3V3
3V3 domain powered.
SB_5V
Standby 5V domain powered.
