$3.5 100W Fake TDA7294 Amplifier Board From Aliexpress
Not bad for a $3.5 fully assembled little amplifier with built in rectifier and 2200uf Filter capacitor.
Capable of delivering 53 Watts RMS with 8 ohms load.
Although the TDA7294 on this board is fake it is still a good cheap amp board that can pump 53 Watt RMS into 8 ohms load, the chip can be replaced with a genuine one if desired later on.
Size- 50mm X 50mm
Height Clearance 29mm
TDA7294 Amp Module 8 Ohms Load Max Power Output Before Clipping
The Amp board has a bridge rectifier built in to the board so an AC source can be connected to the board directly.
Built in Bridge rectifier on board
Filter capacitor - 2200uf 50V x 2
Power Supply used - ±40V
Load used - 8 ohms

So is this original TDA or fake chip?

The chip on this is a fake the genuine ST IC can do 70W RMS and this board can only do 53W using ±40V power supply. At just $3.5 each , is it good value? buyers decide considering the genuine chip cost $9+ each if bought individually (price based from mouser).

@@boknoynaruto3824 Thanks, just as I thought. It isn't just 53W of power but also durability of chip. Anyway nice review.
