Ordered on 08/07, received on 02/08. Not bad for the price paid, even if Im sure dispatch can be reduced about at least 2-3 days somewhere. But still fine.

Module is really tiny, and pins have 1.3mm pitch. Its highly recomended to use a backplane pcb, with a properly designed ground plane, avoiding off course the antenna area from it.
Connected Li-Po 18650 3.6v battery. Device worked fine from first time. Appeared as Speakers on Win10, under "DL-LINK". The audio quality is correct, since its not high end. Power output is powerful enough 40mw per chan @32ohms and drived nicely 40mm drivers headphones.
As reminder: DONT connect AudioCommon to GND. Audio negative is floating at 0.9v. It would damage the chip and apply over drain. Controls from GPiO works fine prev/next/vol+/vol- and BLed status works. RLed never lit, and nothing happens when applying 5v to CHG pin. Maybe CHG current must be set in some way OVC3860 firmware. I wonder how i could use the small charging feature, but ill go for external chg module; ill find out.
NEXT point: The noises. Noises is heard when powering up, and in idle. In fact, if the module is used as is, it will be noisy. Its a shielding issue, and what is heard is actually RF bursts, from BT output.
Otherwise, this device is worth the price and could be used in DIY projects.
Just Dont connect Audio comon to ground, use decoupling capacitors in series instead positive and comon

very small but works very well in combination with an amplifier (pam8403). a lot of functions and a normal approach. the diagram of the ports can be seen under ovc3860. erg klein maar werkt erg goed in combinatie met een versterker (pam8403).
erg veel functies en een normaal berijk.
het schema van de porten is te zien onder ovc3860.
