Power Control is handled by the MC13892 power management IC (PMIC).

Input voltage

Connect any voltage between 6V and 12V DC to the power plug. HW REV 2.1 allows up to 24V DC.

Power up/down

  • Power up
    • The SBC is automatically powered up if the input voltage is supplied.
    • If the board is in power off mode (e.g., after a shutdown in Linux), hit button S3 to power up the board again.
  • Power down
    • If Linux is up and running, you can hit button S3 to execute the command /sbin/shutdown -h now. This will shut down Linux cleanly.
    • Alternatively, type
shutdown -h now

in Linux to shut down the SBC. The PMIC shuts down all voltages after shutdown is complete.
