Electronic DIY Dual-Channel Bluetooth Speaker Kit Stereo Amplifier, Soldering Assembly Practice Board, Audio Module

This electronic DIY kit is designed for audio enthusiasts and beginners who want to learn and practice soldering, circuit assembly, and debugging. It features a dual-channel stereo amplifier with Bluetooth input, allowing you to build your own small Bluetooth speaker system from loose components.The kit is supplied as loose parts and a PCB board, ideal for welding (soldering) practice and hands-on learning. By assembling every component yourself, you can improve your soldering skills, understand circuit structure, and gain practical experience in electronic production.Integrated Bluetooth module supports wireless audio input from mobile phones, tablets, and other Bluetooth-enabled devices. Dual-channel stereo output delivers clear left and right channel separation, suitable for use with DIY speakers, small desktop sound systems, and educational audio projects.This kit is perfect for debugging practice, allowing users to test voltages, check signal paths, and locate faults during assembly. It is well-suited for electronic hobbyists, students, STEM courses, and training environments where practical circuit debugging is required.Delivered as a complete set of discrete components (resistors, capacitors, ICs, connectors, etc.) plus PCB, giving you the freedom to recognize components, adjust layouts, and deepen your understanding of amplifier circuits. You can match your own speakers, power supply, and enclosure to build a Bluetooth speaker.Color: As ShownMaterial: PCBPackage Contents:1*Bluetooth Speaker Electronics KitOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
