The HU-055 Bluetooth stereo mini speaker DIY kit includes a complete set of accessories, such as an amplifier motherboard, speakers, and a transparent acrylic casing. It requires soldering and assembly, supports Bluetooth wireless playback and wired AUX audio input, resulting in a dual-channel stereo speaker. It’s perfect for electronics beginners practicing soldering and for parent-child craft projects, allowing them to learn about audio amplification and Bluetooth radio circuitry while soldering.
Key product highlights:
1. Dual-channel stereo output, clear sound quality
Equipped with a dual-speaker stereo audio amplifier, the left and right channels output sound independently, providing a better soundstage compared to mono kits. Music can be played immediately after assembly, making it highly practical.
2. Bluetooth + wired AUX dual input mode
Supports Bluetooth wireless connection to mobile phones and computers; a reserved audio input interface allows connection to an audio player via an audio cable, freely switching between the two playback modes.
3. Transparent acrylic visible shell
The assembled shell is transparent, clearly displaying the internal circuit board and speaker structure, providing an outstanding display effect and a high-tech feel, suitable for desktop display.
4. Excellent electronic soldering training kit
The kit includes various commonly used components such as amplifier chips, capacitors, resistors, potentiometers, and speakers. The soldering points are moderate, with a friendly level of difficulty, making it easy for beginners to debug successfully.
5. Built-in volume control knob
The onboard volume control knob allows for direct manual volume adjustment after assembly, making it simple to operate and ready to use out of the box.
6. Type-C power supply interface
