Development Kit for Amazon Alexa AVS

The development kit for Amazon AVS (ZLK38AVS) has been specifically designed to provide a platform to integrate Microsemi AcuEdge™ multi-microphone array ASR-Assist technology with Amazon AVS.

The development board interfaces directly to the Raspberry Pi 3 board. The kit contains hardware and software needed to evaluate Microsemi’s ASR-Assist technology with a 2 microphone array.

The ZLK38AVS development kit provides a number of benefits including: 

• A platform to integrate Amazon AVS

• Reference code to implement smart speaker functionality

• Developer access to Alexa Skills

• A platform to evaluate Microsemi’s ZL38063 

The key component of the kit is the ZLE38AVS Development board featuring the Timberwolf ZL38063 Microphone Array ASR-Assist Audio Processor. 

The development board also brings out the SPI/I2C and two I2S (TDMA and TDMB) buses to headers, which allows the card to easily be hooked up to a host microcontroller board, such as a Raspberry Pi.
