pyControl - Audio Board




Audio board

Audio amplifier board for driving a speaker to produce auditory stimuli. The board uses the micropython DAC for stimulus generation. The audio board must be plugged into a port on the breakout board which supports DAC output and I2C serial communication (used to set the volume) - ports 3 and 4 on breakout board 1.2 are suitable. 

In addition to the digital volume control there is a manual volume control knob (the small blue potentiometer on the board) that can be used to calibrate the audio volume.
