2x5W AMP click PID MIKROE-2477 2x5W AMP click functions as an amplifier and features the TDA7491LP 2x5-watt dual BTL class-D audio amplifier. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over the following pins on the mikroBUS line AN, RST, CS, PWM, INT. 2x5W AMP click features a 3.5mm input jack and four output screw terminals for connecting passive speakers. Note In order to achieve full 2x5W output power, keep in mind that you need to supply enough current to the chip.
