lapis v1

soooooooooooooo close

features

Bluetooth 5.4
One large Speaker Driver (I had to dremel the aux port on every board to even make it fit lol)
400mah - 6 hour battery life at moderate volume (calculated)
USB-C PD supported charging port
3.5mm auxiliary input (sadly only input)
Stereo pairing capability when you buy 2. They will connect and play bluetooth in stereo :3

the not-so-great stuff

I iterated this to be the best quality speaker, while being easy to make and financially viable......... but nothing is perfect

something with the master/slave stereo mode makes them get corrupted when more are on at one time
no response from the board seller of these (DAU / BenLi Audio) about their firmware issues
I found who makes the bluetooth chips but no firmware to be found

what's next

might have to figure out how to flash my own firmware or just make another big revision with a different board altogether. The goal is still making these sound awesome while being easy to build!
