Key Features

• Lossless Decoding: Supports high-quality audio formats for a rich, wireless listening experience.

• Dual Power Input: Power it via a standard Micro-USB cable (5V) or connect a 3.7V Lithium Battery directly to the solder pads for portable use.

• LED Indicator: Built-in blue light indicates pairing status and connection stability.

• Plug-and-Play: No complex programming required. Simply power it up, pair your device, and start streaming.

• Stereo Output: Standard 3.5mm interface allows you to plug in headphones or connect directly to an external power amplifier.

Electrapac Pro Tip: This is a decoding board, not a high-power amplifier. For driving large speakers, connect the audio output of this board to an amplifier module (like the PAM8403) also available at Electrapac!

Ideal Applications

• DIY Bluetooth Speakers: Perfect for small, portable speaker builds.

• Car Audio Upgrades: Add Bluetooth functionality to an older car stereo via the AUX input.

• Home Theater: Stream music wirelessly from your phone to your home audio setup.
