I would accept your hunches over mine (and hey, autistic solidarity - me too!), but I only own an Uno and a Nano. I don't own any other microprocessors with which to test this hunch of yours. Is there any way to adapt the boards I do have or would your advice be to find a purchase a different microprocessor that only outputs 3.3VDC? And if so, any specific recommendations?
If you can look at the 2 chips near the SDA pin and get the part number it would confirm my hunch.
I did my best with my illuminated magnifier, but those are tiiiiiiiny and my 42-year-old eyes couldn't make out much more than scratches. My brain kept wanting to say it looked like "Rin" but that wouldn't make sense, so I'm guessing it's just too tiny for me to see without maybe busting out my DSLR with a macro lens.
Here is what worries me. This chart shows a TCS34727 as using 1.8VDC while the TCS34725 uses VDD which is probably 3VDC or 3.3VDC it will NOT be 5VDC. I am confused by this information.
I am even more confused. I hope we can make some sense of it.
