Description

JAB1 is a stereo audio amplifier board integrated with Bluetooth 5.0, delivering 15W output power per channel into an 8Ohm load. JAB1 offers a high efficiency wireless solution for customers, suitable for portable speakers, Bluetooth speakers, home audio, DIY audio, etc. Its excellent self-dissipation eliminates the need for an external heatsink. Compact size and light weight make JAB1 applicable to almost any audio projects. A DC12V-24V power supply is required.

Integrated with Bluetooth 5.0

JAB1 is integrated with high performance Bluetooth 5.0 module, which means you can connect JAB1 with any portable devices or PC to easily access streaming audio via Bluetooth paring. In addition, the module supports changing Bluetooth name, so you can customize your name of JAB1. There is a built-in Bluetooth antenna equipped on the board for stable connection. So you can directly pair JAB1 with the Bluetooth for audio playback. An external antenna port is also provided for such applications that JAB1 needs to be integrated into a cabinet.

Supporting Line Input

Beside Bluetooth input, JAB1 also supports 3.5mm AUX IN. But the two input methods cannot be used at the same time. Based on the insertion detection circuit, once the 3.5mm AUX IN cable is inserted, the input method will switch from Bluetooth to line input.

High Quality Audio Performance

Thanks to dedicated PCB layout design and engineers’ attentive debugging, this JAB1 audio amplifier board features high audio performance, whose THD+N performs well as 0.03% @ 8Ohm, 10W, 1kHz.

Multiple Power Path

A DC12V-24V power supply with output current higher than 1A is required to power JAB1.

In addition to power supply, JAB1 also supports battery power, which greatly improve the portability and flexibility of audio systems. MPPT circuit is equipped in JAB1, so it can recharge the batteries with a power supply connected.

It is recommended to use WONDOM Battey charging and protection board (JAB - BE) designed for 3pcs 18650 Lithium-ion batteries in series as it’s equipped with full protection circuit for operation safety. A 15V-24V, 1A-5A power supply would be required for the purpose to fully charge the batteries.

If you use rechargeable lead acid batteries, a 15V-24V, 1A power supply is needed.

You could also use solar panels for their applications. Just remember to use solar batteries with float (open) voltage with 16.5V-21.5V, and use 20-100W panels for this application.

8 AA (Alkaline) Batteries in series will be 12V to power the amplifier. Please note that AA batteries couldn’t be connected with charging port unless MPPT module is removed.

Easy for Installation

Four screw holes provided make this Bluetooth amplifier board easy for installation and quick for integration in any cabinet. We provide a Functional cables kit (JAB - FC) for your convenient operations. Furthermore, a 3.6’’ x 2.7’’ L-style aluminum bracket (JAB - LAB) is available to fix the Bluetooth amp in wiring process and to install the board to cabinets.
