LB3256 (BK8000L) bluetooth module from ICStation.com, used with PAM8403

In this video I show you a BK8000L based LB3256 bluetooth module, which can be used to make portable bluetooth speakers. As a test I went rogue and did something that all the information I was able to find adviced not to do: used PAM8403 amplifier. even though this module was designed to be used with amplifiers that have differential inputs. To reduce the gain, I used 47kOhm resistor instead of 10kOhm that is usually used in cheap PAM8403 modules. In this case results were amazing! With different power source, speaker, PCB layout etc things might be different, so I suggest getting an amplifier with differential inputs. EagleCAD library for this module: https://github.com/hugatry/LB3256-lbr This module was given to me by ICStation.
