Yeah, it's an AM612. I think when I originally put this together I didn't realize the low cutoff voltage :|
We'll see how long it lasts...
I guess options then are to add a buck converter or strap AAAs on the back insteadBlack fresnel lens? what?? I might have to find some of those

They are on Aliexpress. Not even expensive.

Black fresnel lens? what?? I might have to find some of those...search on aliexpress

thanks guys, i just ordered a few :)
@berkseo i was searching for buck/boost converters and found TPS61098 which when i searched for turned up on one of you designs :)what i can't figure out just yet is how to wire it up for our application. can you shed any light on that, please?
well, i think i may have sorted it.... GND and MODE to ground. VSUB is 3.3 (or 3v if i do the 61098) out (not being used in this application?).
SW inductor, vin of course, and vmain is the output for the mcu i think

Are these for the S16 smd sensors ? If yes, can you please give me a link of where you ordered them ? I couldn't get any, LCSC sold me the sensors but refused to order the lenses for me, and Senba can send them "for free" but with a very high express shipping fee.
