DIY Audio Spectrum Kit with Bluetooth Module

An educational electronics kit focused on audio signal processing and visual feedback. Measures ~12 × 8 × 5 cm and weighs approximately 250 g. Powered by DC 5V. Integrates a stereo Bluetooth module, dual-channel amplifier IC, custom audio spectrum driver, and 132-colour LED matrix. Designed to drive two 3W speakers (not included). Supports both wireless (Bluetooth) and wired (3.5mm) audio inputs, with automatic hardware-triggered switching to wired mode when the jack is inserted. Spectrum visuals update in real time using multiple embedded decoding strategies. Three tactile buttons (K1–K3) provide intuitive control for power, track navigation, and volume adjustment, with documented short/long press functions. Plastic enclosure ensures durability. Only the PCB kit is included — no speakers, cables, or power supply.
