Spectrum Lamp Bluetooth Speaker Assembly Kit

A soldering-based electronics kit that builds into a complete dual-channel audio system with Bluetooth 5.0, FM radio, digital display, and responsive spectrum lamp — all visible through its transparent acrylic case. Emphasises both technical understanding and usable audio performance in one cohesive project. Construction details: PCB arrives with all SMD and TH components pre-fitted; user performs final interconnect soldering (speaker terminals, 5V power jack, IR sensor, LED driver lines, and FM antenna pad). Housing is precision-cut transparent acrylic with mounting points and cable routing slots. One IR remote provided; speakers, wiring, and power supply not included. Functional overview: Amplifier section outputs 2×3W into 4Ω speakers; digital colour display shows real-time source ID, volume level, FM frequency, and 16-band spectrum analysis; supports Bluetooth 5.0 pairing, FM tuning (76–108 MHz), TF/SD/USB playback, optical input, and LINE IN. Powered by stable DC 5V (2A recommended), drawing ~1.1A during playback and ~40mA on standby. Use-case readiness: Though a build kit, it achieves full standalone operation post-assembly — no PC or app required. Ideal for STEM education, maker spaces, or self-paced learning where functional outcome reinforces foundational concepts like amplification, modulation, and digital signal interpretation.
