HW-770 Bluetooth Module Review
HW-770 is a good bluetooth module board with stereo sound output and good quality sound, supporting a wide range of profiles and 4.1 bluetooth, it is worth for buying.
But there is really one annoying and disturbing thing about the board: the annoying chinese lady sound each time you connect and disconnect bluetooth, this is a major downside, and other than this, the board is a useful one!
