ZL38063 Audio Processor Development Kit 1200MHz CPU

Product Description

The development kit for Amazon AVS (ZLK38AVS2) 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 1, 2 or 3 microphone array.

The ZLK38AVS2 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
• Optional USB audio port

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.
