On the 3W PAM8803 module, which PIN is the RST input?

I'm not seeing a schematic from the board pinout.

There's 3 different GND inputs - I've tried all of them.

thanks!

Since there is no obvious reset RST pin brought out to the connectors I used the SDN pin. This pin must be kept at logic high for the module to work. The library reset function toggles it low then leaves it high so it appears to be acting as a Reset.

Pin 15 RST on the pam8803 module i have appears to be tied to GND on my module so I don't see how'd you'd use that as a reset and retain the connection to GND.

If you are getting unreliable odd behavior as I did try putting LEDs on Vup, Von, and reset and make sure you can see them changing.

Yes, I used SND too as reset method.
