Description
Module with PDM microphone. PDM is a digital modulation in which the signal value is represented by the pulse density. The PDM signal can be treated as a stream of bits in which the signal value is expressed by the length of the sequence of ones. PDM modulation can be received in a digital way, so you do not need an analog-to-digital converter to operate the microphone. A 1 ... 3 MHz clock signal should be attached to the module and the output signal will be synchronized with the clock.
