VOICE BONNET ADDITIONAL CAPABILITIES
The Voice Bonnet also includes a dedicated microcontroller (MCU) that enables the following additional
features:
Control of four additional GPIO pins, freeing up the Pi GPIOs for other uses
PWM support for servo/motor control without taxing the Raspberry Pi's CPU
Analog input support via on-board analog-to-digital converter (ADC)
Control of the two LEDs on the bonnet
The AIY projects page provides some samples how to use these advanced features of the Voice Bonnet as well.
