We need a new PCB version for all the new components:

LD2450 support (#92)
Speaker (#74, #129)
OLED Display (#126)

@mourix I believe that the PCB silk screen has an error. The MAX98357 has the negative on the left side of the board closet to the LRC and DIN. The Silk screen prints the "+" on that side and positions the positive leads in the center of the board for the speaker This in turn can result in the incorrect installation of the speaker orientation. The PTH Pads seem to need to be reshaped and relabeled for the speaker and relabeled for the output of the MAX98357. None of this should result in damage though. adafruit_products_3006_iso_ORIG KICAD_AIOSENSE

@mourix With the speaker orientation reversed per the comment from @jaws35smith I am seeing poor performance on 3013 speakers. Audio, if it comes through at all, is very crackly and unintelligible. On a breadboard using the same pins and configuration I am seeing great performance with Piper TTS.

I recall reading somewhere that MAX98357 likes wide output traces.
