From what I am seeing here:
Similar issue as mine, but instead they needed it LOW and to stay LOW.
From the GPS module (not the gas sensor I am using), the En is:
EN is the Enable pin, it is pulled high with a 10K resistor. When this pin is pulled to ground, it will turn off the GPS module. This can be handy for very low power projects where you want to easily turn the module off for long periods
^ Now this makes sense to me.
However, on the gas sensor it seems to be the opposite:
You can use the EN pin to power it off (pull it high to 5V to turn off) to conserve energy.
^ This simply does not make sense to me. It should be the opposite (same as the GPS module)
So the question to summarize the question I am not understanding: without cutting anything, and without adding external circuits, is there a way to deliver any low voltage (where 0 < V < 3) on a pin while the photon is in a sleep state, where that voltage can be turned off on wakeup/run (that is, not like the dedicated Vin or dedicated 3v3 pin)?
@ScruffR ^ this last part is what I don't currently understand.
