How do you charge it?

  • 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.

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

  • 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 sound and quality for such a small item. It easily paired with my Samsung Galaxy Note 3. Great bluetooth receiver/amplifier for DIY.

    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.
