I recently received the Particle Shield Shield and after putting it through some tests I don’t believe that it is performing as it should. Issues that I am experiencing include the Shield Shield’s 3v3 pin not outputting any voltage and the voltage conversion not being correct.
For example, a 5V source into the Shield Sheild’s Analog pins translates to more than 3.3V (3.542V) to the header pin for the photon’s ADC. I also tried putting a 3.3V source into the Shield Shield which if I understand correctly should result in 2.178V output (3.3V/5V=0.66*3.3V=2.178V). I’m showing an output of 0.283V. Do I have a defective unit, or am I misunderstanding the capabilities of the Shield Shield?
