Stereo Power Amplifier Module Bluetooth 4.2 5W+5W Audio AMP

Description:
1. Bluetooth 4.2 version, compatible with all mobile phones and Bluetooth adapters on the market. The transmission distance is about 15m/49.2ft in an open area, and it supports automatic connection to the paired devices and automatic playback of music.
2. Support USB sound card, free drive, plug and play (under normal lithium battery power supply). The maximum working current is 5V2A, powered by a regulated power supply of 5V2A or above, the sound quality will be better.
3. Two speakers of 2‑8Ω and 3‑10W can be connected respectively, and 4Ω5W and 4Ω10W speakers are recommended for stereo output.
4. Built‑in USB charging port, it can be powered by a USB port or a 5V adapter, which is convenient for using.
5. When installing the Bluetooth board, try not to place the Bluetooth antenna close to metal parts, so as not to affect the transmission distance.
6. The built-in dual 5W power amplifier circuit must not be used with another power amplifier! The outputs of the two power amplifiers cannot be connected in parallel or the negative poles connected together, otherwise the power amplifier chip will be damaged.
