Module with audio amplifier class D MAX98306. Small power losses, that is small heat generation and longer battery life. It allows you to connect a 3 Ohm speaker with the power to 3.7 V.
The system inputs are differential, a safety input signal from the primary circuit, for example, Arduino Mp3 Shield. In the absence of a device with differential outputs, connect pin Audio.
The output of the module is the Bridge Tied type. This means that the output contacts are connected directly to contacts of the speaker, without connecting to the ground. The output is a PWM signal with a frequency of 250 kHz, which is averaged through the coil dynamics - high frequency is not audible. For the module, it is not possible to connect another amplifier. It should lead directly to the speakers.
