The XPCB-12BT Bluetooth audio amplifier board features STMicro’s TDA7492P dual BTL class-D amplifier IC. The board features two 25 W outputs that can be used to power speakers and exciters for any design in a small 73 mm x 48 mm package. This makes the XPCB-12BT an easy audio amplification circuit solution for any designer or engineer and would be a perfect tool for any maker or IoT project. The board allows users to connect to the input via Bluetooth or 3.5 mm wired audio aux connector. The board can be used for 4 ohm, 6 ohm, 8 ohm, and 16 ohm impedance speakers but is ideally made for 8 ohm.
