Bring your amplifier case design projects up to date with our new Bluetooth Amplifier Kit and play music from a phone, tablet or computer wirelessly. The kit is available in 3 different formats; on its own with no speakers, with 4ohm 65mm speakers included or with 8ohm 100mm speakers included. For the two speaker options, the speakers are supplied unconnected to allow for cable lengths and cable routing to be personalised to specific enclosure designs. The power switch for all three options is supplied unmounted so an alternative power switch can be used.
The amplifier at the heart of this kit is a 3W Class-D amplifier which not only delivers excellent audio quality, it is also very light weight and doesn't require the use of a heat sink. This greatly reduces the factors that need to be taken into account when designing your own enclosures.
The user interface is a simple on/off switch. When powered on, the Bluetooth module has been programmed to automatically try to reconnect to the last device it was paired with and where this is not possible it will instead enter pairing mode. After testing various iterations, we determined that automating this process led to a much more satisfying user experience.
You can power the Bluetooth Amplifier Kit using either a 1A USB supply or LiPo battery(with JST connector). Both available separately. It also features an integrated LiPo battery charging circuit, for battery capacities between 400mAh to 1000mAh, for those who also want a portable mains free solution, with automatic battery charging and switch over between PSU and battery (when battery present). A 1000mAh LiPo battery can provide up to 28 hours of continuous operation at normal volume.
The board features an LED and sounds which are used to indicate status information, such as pairing status. There is also an optional connection point for an off board LED, for designs where the USB power and LED want to be on different enclosure faces.
- As the speakers and the power switch are supplied unconnected, some soldering is required.
- Speaker wire is supplied with all three buying options.
- 3W audio amplifier with Bluetooth link (based on a fully CE compliant module).
- Play music from a phone, tablet or computer wirelessly.
- Simple user interface, via single on / off switch.
- Auto reconnect or enters pairing mode on power up.
- LED and sounds indicate status information such as paring status.
- Optional connection point for additional off board LED.
- Can be powered from a 1A micro USB supply or LiPo battery (both available separately).
- Includes automatic LiPo charging for battery capacities between 400mAh to 1000mAh.
- Speakers supplied unconnected allowing cable lengths and cable routing to be personalised to specific enclosure designs.

Hi Morgan, The weight of the kit by itself is approximately 25g, if you went with an option with speakers it would weight more depending on the speaker type you picked.Posted byon Friday, 3 March 2017
Hi Shivam, Did you mean does it come with speakers? This product has three possible buying options, without any speakers would be product code 2160, with 65mm speakers would be product code 2160-A, and with 100mm speakers would be 2160-B. If you scroll down on the product page there is a table showing the buying options, it can be found past the photos and product description, just before the dimension information.Posted byon Monday, 27 February 2017
Hi Noah, The board hasn’t been designed to allow you to do this, as such you would have to modify the board to allow a microphone to be added, even then the Bluetooth module hasn’t been programmed to work the same as a hands free device.Posted byon Tuesday, 7 February 2017
Hello, We wouldn’t recommend this as the Bluetooth amp kit is powered by 5V’s and the high powered amp kit is powered by 12V’s. Also the signal out of the Bluetooth would need to be reduced (attenuations) before it could be feed into the high powered amp kit to avoid distortion. We also haven’t tried this our self to confirm if it is possible, but in theory it could be done.Posted byon Friday, 13 January 2017
Hi, i would just like to follow up regarding the below. I have now been informed that unfortunately the output can't be fed into anything else even if attenuated. This is because it uses a differential output and not a line out style output. I apologise for any confusion caused.Posted byon Tuesday, 31 January 2017
Hello Jeroen, We have tested the kit here and it can handle 10 meters, with a wall as an obstacles, however certain conditions may reduce this range and 10 meters did appear to be the limit before it started to loss connection.Posted byon Wednesday, 18 January 2017
Hi Dave, We are currently processing the first build of this kit and are looking at placing a small number into stock in the next day or so. We will then finish the build and add the remaining stock in the near future.Posted byon Thursday, 12 January 2017
Hi Richard, those are the only two items that would requiring soldering, all the other components are pre mounted onto the board.Posted byon Wednesday, 11 January 2017
Hi Chris, as this is a Bluetooth amp kit you wouldn’t connect an iPod lead to the kit, you would connect via Bluetooth. This kit should be available in stock in the next few days as we are just finishing the first batch of manufacturing.Posted byon Tuesday, 10 January 2017
Hi John, without knowing the reason for wanting to add a potentiometer it is difficult to say. However it is likely that it may not be simple to alter the kit, as such we wouldn’t recommend making changes to the kit.Posted byon Tuesday, 28 March 2017
Hi Fergus, You could technically add a third speaker by connecting it in parallel or series with one of the other speakers. However you need to ensure the impedance doesn’t go below 4 ohm’s and is the same as the other output. For instance, if you had an 8 Ohm speaker on output 1, you could connect two 4 Ohm speakers in series to output 2 giving a total impedance on 8 ohm’s on that channel. If you wanted them in parallel you would use two 16 Ohm speakers. If you were wanting to add a third channel to the kit it wouldn’t be possible as it is a two channel amplifier.Posted byon Monday, 24 April 2017
