Did you have any luck with the power issues on the new board?

The new board hasn't come yet, but a friend gave me a great idea, to power the mic from a GPIO, which powers it off completely when the ESP is off.

Hopefully the new boards will be here soon, but another issue is that I don't really have anything that can measure microamp consumption, so any testing takes days of waiting for the battery to run down :(

I do think these clones are the issue, though. They had a LED I couldn't turn off, so they'd literally shine forever. They don't seem engineered for low quiescent current, so fingers crossed with the new ones.

Is it worth removing the led from the board? Wont help with any other decisions by the designer that draw excess current, but maybe that's the only or largest one?

		I did remove it :( It's still pretty bad. I ordered some Xiaos that do explicitly say 14 uA sleep current, but they seem to have gotten lost in the mail!

Makes a lot of sense :) thanks for the update.

I'll try to remember to creepy stalk you for updates as the device sounds great!

		Thank you for the blog/updates. Since you're deep into this space, Do you use wall mount dashboards? There seems to be two camps now: Dashboards everywhere or none at all.
