This audio module fits right on the pyboard and allows you to record and play short sounds, as well as play generated waveforms. It uses the DAC (for output) and ADC (for input) on the pyboard, and has a pre-amp on the microphone and small power amplifier on the speaker.
The output volume is controlled by a digital potentiometer, and it can be easily set in software. The digital potentiometer is an I2C device (a MCP4541).
This module is not compatible with PYBLITEv1.0 or PYBLITEv1.0-AC. Pyboard lite does not have a DAC and so cannot output analog audio signals.
This module requires some assembly. The speaker, microphone and male header pins are supplied with the module as loose components (see picture) and need soldering onto the PCB of the module. See here for a video tutorial on soldering the components.
