Electronic Spices Combo of PAM8403 Amplifier Board with Bluetooth Audio Receiver & Micro USB Battery Charger Module

The media could not be loaded. Nothing to say, osm good product. Value for money, sound quality is super and functionalThank you

Good❤️

The media could not be loaded. My F&D USB soundbar was not working, I opened it and found that USB cable was torn off from the board. Repairing it needs special tools and techniques. So instead of repairing the board I bought this. I got 3 pcb boards. 1st one for battery circuit, 2nd for amplifier and the 3rd for bluetooth. I didn't used the battery circuit. First found the + & - of the 5 V input of sound bar. Soldered both amplifier and bluetooth circuits with 5 V supply of the existing sound bar board. Then bluetooth left, right, ground signal points were soldered with amplifier boards. Right and left speakers wires were cut from the old board and soldered with amplifier board. It's very important to solder right polarity of speakers otherwise the speakers won't make sound. Every thing went fine and speaker is working. However the speakers are making slight hissing sound when idle and connected to some device. May be because of my bad soldering. Sound output is good. Very much enjoyable for listening old 50s -80 s songs. News and other YT channels on science, technology, study etc. However, audiophiles may not like it. This makes a chime sound when on, connected to a device and disconnected from a device, see the video.Important points before you proceed:1) pcb boards are very small. 2 - 4 cm in length and width. Hence soldering with ordinary soldering iron will be extremely difficult. I faced it! You need fine tip (pencil tip) soldering iron for perfect soldering.2. Never use voltage supply more than 5V (+/- 10%) overvoltage will fry the microchip. Connect correct polarity.3. Left right ground signal points should be correctly connected. Else sound will be reversed or no sound.4. While connecting the speakers to the amplifier board +/- polarity must be correct, else speakers won't make sound.5. Use thin insulated wires. I have used thin wires of old tubelight brackets. You can also use 22- 28 gauge magnet wires for this purpose.I am fully satisfied with the performance of the bluetooth and amplifier circuit boards. This is an absolute value for money product and highly recommend this.

Based on the product received giving a one star also is shameful thing.I mean who makes a circuit/ pcb so tiny that can not be properly solder or difficult to make any connection.The boards are so tiny that making a circuit is impossible with them.Waste of money.Atleast charge more money but mKe a good size board.Do not buy or order.

Very good and Bluetooth sound very good

Good condition and Better performance with bt... Value of money ☺☺

Amplifier board is okay but if you increase volume above 60% is start losing sound start cracking noice spend Litt bit more money and go for PAM 15V or 30v! Bluetooth Bluetooth is really amazing connect with in seconds ❤️Real problem is charging board!Right after connecting to charge start getting heatup crazily! Almost burnt by it twice!And when I connecte with 18650 oh man it start melting! Not that good experience!

Very good
