With this module, you can record a message by pressing one button and then play it back on a speaker connected to the module by pressing a second button. The module works with pulse width modulation (PWM) and the conversion of this digital pulse train into an audible signal is left to the inductive load and mechanical inertia of the loudspeaker. A cursor measurement on the oscilloscope gives an impression of the frequency of the PWM signal, which is around 2.7 MHz. We have recorded some music samples from the album 'The Wall' by 'Pink Floyd' and found a maximum recording time of 2 minutes and 16 seconds. So that's pretty much what the specifications promise.
