Q

How do you charge it?

A
  • You don't charge it, it requires constant DC voltage. 12 to 24 volts If I remember correctly. This board contains no battery for you to charge.

Q

How do we switch the source between aux input and bluetooth?

A
  • Simply connecting the aux in, or connecting with a Bluetooth device worked for me. I have this set up with indoor/outdoor speakers. The Bluetooth and Aux seem to be on constantly, simply connect to one :3

    I used this to make a Bluetooth speaker with my son for fun and it works a treat! Easy to connect too functions work well, only annoying think is the loud bleep when it's switched on, it's not audiophile quality but it's £14 so I wasn't disappointed.

    Really neat design/idea. I have used this in my garage to power an external speaker for the garden. Bluetooth is a bit sketchy through walls but that could be my phone.

    I bought this for making a prototype of a new product and it worked very well. extremly easy to set up, it worked well both as BT speaker and a speaker phone. I have just tested it in a lab set up so it is to early to judge the final sound quality yet.

    Great bit of kit and arrived alot quicker than I'd expected. Apart from the start up beeps being unnecessarily loud, I cant say a bad thing about it.
