I am looking for the preferred way to power the Argon using an external power source. We will not be using LiPo or USB.
On the Photon we would connect a 5v supply to Vin. I don’t see a Vin pin on the Argon. Do we use the Vusb pin at 5v? It it written in the docs as it’s output only. Or is it preferred to use the 3.3v pin and disable onboard regulator?
Please advise and thank you!
