Bluetooth stereo amplifier

Assembly of a 5 + 5 watt stereo Bluetooth audio amplifier. Starting from the CT14 module of ICStation, a wireless stereo amplifier is built. The amplifier is powered by a high capacity Li-ion battery. The charging module with TP4056 protection is mounted to charge the battery, and a pair of recycled speakers are used. The whole set is assembled in a custom made wooden box. A support made of PLA is also built to mount the two PCBs and the battery inside the box.
