Im trying to use a max98357 for audio and this screen (https://ebay.to/2YsuX2t) at the same time but it looks like certain pins overlap. I have no idea how to use both at the same time and cant seem to find anything online... help?

the only GPIO that might overlap is for the back light (LED)
if using this method (or similar) to enable the SPI LCD

you might be able to use another GPIO .....
but another alternative is to wire the back light (LED) to the 3.3V....
this can easily be done with the aid of a resistor (around 3.9ohm)

again....
you may be able to use another GPIO instead (someone else may be able to confirm/clarify this)
but wiring to the 3.3v is a quick work around

sounds like someone in discord said just bridge the backlight pin with the vcc pin? screen is 3.3v so i shouldnt need a resistor? thanks again veteranyou might be able to use another GPIO .....

About max98357: https://learn.adafruit.com/adafruit-max ... p/overview
Resistor can be from 3 to 20 ohm if Vin is 3.3V
