[警告]

When using CON14 do not supply power from CON15 at the same time. It may cause damage.

[警告]

When using the AC adapter, connect the DC plug of the AC adapter to the Armadillo-IoT first and then plug the AC plug into the outlet.

[警告]

When using the AC adapter (OP-AC12V5-00) when re-powering, wait at least 3 seconds before turning on the power.

When turning on the power using a power supply unit other than the above AC adapter, please do so with a monotonically increasing supply. Also, when re-powering, make sure to first turn the power off (5V or less for at least 10ms) and then turn it on again.
