Does this have a coupling capacitor? I want to drive drive from an Arduino PWM pin

According to the data sheet this device is driven by a digital output, so no coupling capacitor would be required.

How much is the gain?

Hi Tepalia,

Looks like the amp chip is rated for 2W, but the speaker is only rated for 0.15W. Any other specs you were after?

Is there a PCB footprint / drawing we can use for adding connectors / screw holes for permanently embedding this into projects?

Hey @Kaylee9,

Unfortunately, it doesn’t seem like a PCB footprint exists for this module. However, I pulled one from our stock and measured a few of the sections that may be useful to you (please excuse my MS Paint art skills).

The middle mount point is centred left to right with 15mm between its centre and the sides. It sits 9mm from the bottom of the board. This is a 4mm diameter hole

The left and right cutouts sit 17mm from the bottom of the board to their centre. These cutouts are semicircle with a diameter of 5mm.

Hope this helps!
