A part of the review has been auto-translated.
I am impressed with this little board. It is a high quality electronic device that do perfectly what it claims. The device can play music from sd card (I only tried mp3 files but as I saw in the internet can play other formats also), it can act as a FM Radio (the only thing that needs for this operation is a small antenna to be soldered on the board), and finally can play music via bluetooth. I paired the device with my iPhone and the results was totally amazing. The sound quality is high, and the IR control can manipulate the device from tenths of meters. I also noticed that the bluetooth range was long enough. I heard music with the earphones from my iPhone with was two rooms away from me!! I suggest this device for all those want to construct an integrated device for wireless sound.
