Thanks for your interest in the Intel Joule Platform.
We appreciate the links provided. Looking at those links, we would like to let you know that in the Ark.intel page the DC voltage range of 3.6-5.25V is regarding the Joule module, moreover, the correct power supply you need to use are 12V 3A as it is mentioned in the Intel Joule Module User Guide. However you can connect the Type C USB cable to power the Joule expansion board, but you may have an issue with rebooting, so for general operation, we’d recommend use 12V power supply.
Hope this information helps to clarify your inquiry.
Great. Thanks for the quick reply. Answered all of my questions.
