I am attempting to assemble a weather station as outlined in https://learn.sparkfun.com/tutorials/ph ... -guide-v11 using an external 12v power supply attached to the barrel connector or screw connectors described in the article. However when powered this way, the particle photon will not boot successfully. I can only get the weather shield and photon to work correctly when powering the photon via the USB connector. I have measured the voltage on the 3.3 volt rail when externally powered via 12v and it measures roughly 3.25v. Has anyone successfully used the photon weather shield with external power?
