Table 1: EVK-IRIS-W1 power sources
The power sources are protected from reverse polarity by protection diodes, allowing multiple
sources to be present simultaneously.
Only if the power protection circuits are left intact can the USB be safely connected at the
same time as external power. This makes the programming of the module easier.
⚠
The EVK USB type C connectors are only capable of handling 5 V input. Do not connect the
12 V supply.
