Wiring Diagram doesn't show reason for the Audio Amp? Only shows it as power source for the Dev Kit about 01

I think that's just a typing/albel error, it's not an audio amp, that is the power boost, as written in the center of the PCB:

yeah that makes a lot more sense, so this:

Yes, except the BOM (https://github.com/OpenInterpreter/01/blob/main/hardware/light/BOM.md) recommends a Powerboost 1000, but on the diagram it's a 500 model. Strange

[contractorwolf]

it might also be helpful to list this specifically as the micro needed (to get the onboard speaker and microphone):

This is important because the one adafruit carries in NOT the one that is needed (they carry the Matrix which doesnt have speaker or mic)

[contractorwolf]

the adafruit 1000c is this one:

but that doesnt look like what is in the picture and is probably overkill in my opinion. I ordered the 500 so i will report back when I have had a chance to test it (waiting on the echo too).

Question for all, Battery Bottom 110mAh for M5Stack Basic V1.1 - would this be enough to power the echo component, obviously wouldn't have the switch connected, but it would seem this would be enough? Albeit with less battery.

Just made PR #183 to relabel the diagram. It still shows a 500C powerboost instead of the appropriate 1000, but I don't have Fritzing on my computer to get a different image atm. At least it will be labeled correctly. We were experimenting with an audio amplifier to try out a better speaker for the device, and mislabeled the diagram.

Regarding your question @ryanmcdonough, I'm not sure exactly, it seems like it would be enough to power it, but not for long. Let us know if you end up trying it with that battery bottom!

that battery wont last but 20minutes I am guessing. Remember you need to boost that 3v up to 5v and that device will be trying to maintain a network connection to wifi the whole time. 500mah might be an hour or more maybe.
