Worked from 1st power up with iphone4 and Win10 BT Stack+generic bluetooth dongle, NO PROBLEM so far. Nice PCB and layout. NO stupid VOICE shouting "BLUETOOTH DEVICE IS READY TO PAIR" or whatsoever; this device is QUIET and only beeps on MaxVol, MinVol and that's it! PlayPause/PREV/NEXT buttons control and module state pin (3,3v when active) . Device connect automatically to last paired device, and it memorize 2 devices. Add the 470uF on VCC/GND pins, works fine from 3,3 to 5v. Keep AudioGND decoupled from GND to avoid noises. Note that AudioOUT is LINEout, not powerful enough for 32ohms headphones. GOOD MODULE!
