Speaker - 3 Diameter - 4 Ohm 3 Watt (ADA1314)

This is a placeholder topic for “Speaker - 3 Diameter - 4 Ohm 3 Watt” comments.

Listen up! This 3" diameter speaker cone is the perfect addition to any audio project where you need an 4 ohm impedance and 3W or less of power. Adafruit particularly … read more

I am a teacher of woodwork and the project for this semester is a bluetooth speaker cabinet. So we need to get a kit/list of components to install in our cabinets. The size and shape of the cabinet can be made to match the bluetooth kit. I figure we need a stereo bluetooth receiver, a battery charger and battery and speakers.

Do you guys have a pre-made kit or at least a list of what we should get from your store. We will be getting 30 to 40 sets, but want to get 4 sets to start with so we can tinker.

Hey Jeffrey,

Unfortunately, we don’t have a whole kit to get you up and running. However, we have a few options that might be helpful!

Bluetooth Audio Receiver Boards
LiPo Charger Boards
LiPo Batteries

You could use a few of these components, it’s a little dependent on the specifics of the project but this should at least get you started. If you post a bit more intel we may be able to make some more suggestions!


My biggest fear is that I buy what I think is good and they are not compatible.
The cabinets will be customised to suit what ever kit I give to the students.
So far I have found the following on your website:

  • Bluetooth 5.0 Audio Receiver Board SKU: DFR0718
  • Speaker - 3 Diameter - 4 Ohm 3 Watt SKU: ADA1314
  • Lipo Charger-MicroUSB SKU: DFR0667
  • Polymer Lithium Ion Battery (LiPo) 18650 Cell (3.7V 2600mAh, Solder Tab) SKU: CE04625

If I buy these components, will they all work together? We have an electronics lab that we can use to solder everything together, etc.

Hi Jeffery,

The audio receiver board and the speaker should work together just fine. However, the Lipo and charger are a bit tricky, if you use this setup you will need to disconnect the battery from the Bluetooth board and connect it to the battery charger every time you need to charge it. Also, the Bluetooth board doesn’t have any lipo protections built-in. I would recommend using a standard USB battery bank this will make it a lot easier to work with.

Hope this helps!

Do you guys sell a standard USB battery bank?

It says on the Bluetooth 5.0 Audio Receiver Board SKU: DFR0718, that I listed above:

  1. Since there is no lithium battery protection circuit on the decoder board, it is recommended to use this module with a Lipo Charger board.

Do you have such a Lipo Charger board?

We sure do :slight_smile:

Yes, though it’s worth noting that all our LiPo cells have built-in protection Circuitry.

I’d suggest using this one:
