Will this board supply power back to the Raspberry Pi through the 50 pin connector?

Yes, the board has a step down converter (MP2403) that powers the Pi through the GPIO connector (which is 40 pins...) I power mine with a 19v laptop supply and it works very well.

How does this interface with the pi? i2c/spi something else?

hi，Glad to answer your question：The Amp works with all Raspberry Pi models with the 40-pin GPIO connector，uses IIC PINS， you can see the detail of the TAS5713PHPR

Will not be used with pi. need to know which pins accept i2s input. can i download user manual?

Manual can be found here http://www.inno-maker.com/product/hifi-amp-hat/ and it does list the pin usage.
