Hullo,

I'm from India and have bought the two module from Eight Audio, a company here in India. Since i've purchased the pre-assembled board their website conked out and there is no support from their side. It didn't come with any schematic or paper. Just plain board. I have the following questions. Both of them cost approximately 12 us dollars.

1. Since both boards utilised two ICs, When fitting a heatsink, do i need to used washers/insulation?

2. Since both can be used in bridge mode. How to activate this?

Thanks
