Looking for a data sheet for it or info on powering it. Will it only accept power via the USB? I hooked up 3.7v to the battery +/- and only got red flashing light. Haven’t hooked up audio, but seens to work with USB connected.
Will the battery +/- charge a lipo battery and then run off of the battery when USB is not connected?
Hello Marc,
Thank you for purchasing.
Actually, the module accept power via the battery +/-. The USB power is charged for the battery. The module should not be charged by USB plug without the connection of battery, or it will appear intermittently promote sound because of the charging protection function.
If you only got red flashing light, that means the module stopping searching Bluetooth device, you can try to wire the module again.
Here is the datasheet of the module Datasheet_B016Y1850U
Hope this will be helpful to you.
Best regards
