PAM8403 2x3W Audio Amplifier with Bluetooth 4.0

Very suitable in combination with small, medium and even large speakers!
3W may not sound like much, but if you use 5V and 4Ohm speakers, a lot of sound will come out for such a small board!
It is based on the Class-D audio amplifier principle, and is therefore extremely efficient compared to normal Class-AB amplifiers that turn half the power to heat!

Specifications:

• Operates on 5V via the micro USB connection
• Very energy efficient
• Numerous protections that give it an extra high "hobby factor". (does not break quickly)
• Works with impedances between 4 and 8 ohm.
• Reverse polarity protection with a diode
• LEDs indicating the status of the bluetooth (waiting for connection, connected to device)
• Volume control buttons: VOL+, VOL -
• 2x 3W @ 5V 1.5A (4 Ohm)
• Dimensions: 60mm x 35mm x 8mm
• JST-XH (4-pin) connector cable needed to connect speakers (sold separately)

The Bluetooth on this amplifier does automatically turn on when the power is turned on. This must first be switched on with the "MFB" key held down for a few seconds. Then it can be found via bluetooth as "SANWU Audio".
