Analog microphone (AMIC)
An analog MEMS microphone is provided on the baseboard for analog audio application. The differential
output AMIC is interfaced with CYW20829 device through the dedicated analog microphone input pin and AGND
pin. This AMIC is powered by the MIC_BIAS rail from CYW20829 device. The AMIC is used to execute the voice
remote code example in the kit.

RGB LED
An RGB LED is available in the baseboard which is controlled through dedicated three digital GPIOs. The three
GPIOs are driven from CYW20829 silicon to drive the RGB LED. Port 0.2, Port 0.3, and Port 0.4 are used for red,
green, and blue LEDs. Power supply is provided from VCC_PER rail and series current limiting resister is given
according to the bias current of 5 mA.
