My Little Hacker: Making an MVP (Minimum Viable Player) for the Baby Einstein Take Along Tunes hack
from Adafruit Industries · host Adafruit Industries
In this segment of My Little Hacker, we've removed the old PCB and it's time to prototype new guts with an ESP32-S2 QT Py and an I2S add-on board. the S2 has stereo DACs but they're only 8-bit and you can't DMA to them, so I2S is definitely the way to go. but can we use CircuitPython to stream 22KHz WAV files over I2S? will the speaker play nice with our MAX98357 amp? and what about that 2xAA power supply, will it work without a booster?
