  • Hello! I will look into the forum, however, to clarify: I am only powering the photon/shield combo with a 9V AC wall wart (through the added barrel jack connector on the shield. The documentation appears to suggest that if this is the only power source, no alterations are needed to the Power Select or 3.3V Disable jumpers...is this not the case?

  • X-post from my comment on the hookup guide tutorial:

    To power my Photon Weather Shield, I purchased a 9V AC adapter wall wart (TOL-15314). By all accounts, this should be acceptable for the rated voltage of the 3.3V regulator on the shield (no modifications were made to the shield itself; no traces cut nor solder jumpers jumped. I understood the shield to come configured to accept ~2.5-11.5V in its default configuration).

    Whenever I plug the board in, the regulator goes into thermal shutdown. It usually takes several minutes, but eventually it just locks everything up. I've been considering buying either a 5V wall wart, tacking on a heat sink, or swapping the MIC5205 3.3V regulator for a different regulator, but I figured I'd ask...am I crazy? I have my setup enclosed in a Big Red Box (PRT-11366) and the reg gets so hot that it actually effects the readings of the shield's onboard temp sensor...not to mention the thermal shutdown
