Absolute maximum ratings are values that should not be exceeded under any use or test conditions, even just momentarily. Please factor in a margin against these values during use. |

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. |

10.4. Power Supply Circuit StructureThe structure of the power supply circuit of Armadillo-IoT is as follows. The input voltage from the power input interface 1 (CON 14) or the power input interface 2 (CON 15) is converted to each required voltage by the power supply IC and supplied to the internal circuits and each interface. Please design the connection of any external equipment and power supplies so as not to exceed the maximum output current value of each interface and switching regulator (DC-DC). | |
