Modified to eliminate the audio shield, and use Max98357A mono I2S chip.
https://smile.amazon.com/gp/product/B07PS653CD/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
Pins: Teensy 4.0 Teensy 3.x
LRCLK: Pin 20/A6 Pin 23/A9
BCLK: Pin 21/A7 Pin 9
DIN: Pin 7 Pin 22/A8
Gain: see below N/C
Shutdown: N/C N/C
Ground: Ground Ground
VIN: VIN = 5V
Gain setting:
15dB if a 100K resistor is connected between GAIN and GND
12dB if GAIN is connected directly to GND
9dB if GAIN is not connected to anything (this is the default)
6dB if GAIN is conneted directly to Vin
3dB if a 100K resistor is connected between GAIN and Vin. */
