Bluetooth 2.1 power amplifier board

Overview

Use two TEA2025B power amplifier chips, one to drive the left and right channels independently, and one to use the BTL solution to drive the woofer alone. The power supply is 8 to 12. The voltage is high and the power is high, and the heat is also high. The chip needs to add a heat sink. If conditions permit, then Add a fan, preferably a separate power supply, onboard M18 Bluetooth module, which can be directly connected to Bluetooth, with its own AUX interface, lossless sound quality input, perfect in actual testing, there is a video in the attachment, I have sent a video in DY, ID electromechanical Xiaowang
