Sure TPA3116 wiring - mute stby vcc and gnd

[DannyBoyNYC]

Hi all,

I've purchased the board pictured below. It works well but I'm a little mystified by the function and wiring of the inputs highlighted. I am ready to put this in a case and would like to know what these do and how to go about wring them.

Thanks for any advice!

Bump! Anyone wanna help out a newb?

Leave them unconnected if everything works. There are pull-up/pull-down resistors somewhere on the board which keep these inputs at default level.

The VCC and GND are simply power supply passthroughs to connect another amp. I ignore the others.

I was hoping to take advantage of the mute. Thanks all.

By default mute is connected to GND via a pull-down resistor, so you have to connect it to VCC in order to mute the outputs. You can add a simple toggle switch for it.
