Aikri QCS404: Aikri-40X-4LD-1

The Aikri 404 development kit is powered by the Qualcomm® QCS404-based Aikri SoM. This SoM integrates a 64-bit Quad-core Arm Cortex-A53-1.4 GHz CPU, dual Hexagon™ QDSP6 v66, 2×2 802.11ac Wi-Fi and BT5.0 connectivity and supports a mic array, multi-speaker connection via Wi-Fi/BT, PCIe and multi-room audio streaming.

The QCS404 is designed specifically for smart audio applications and supports features such as Multi-mic Noise/Echo Cancellation that isolates noisy environments from voice, simultaneous multi-keyword detection to aid voice services like Amazon Alexa and Google assistant. The Aikri 404 development kit helps kick-start and optimize your creation of complex, feature-rich smart audio solutions such as Smart-speakers, Soundbars, Home cinema, Smart assistants, Home Hubs etc. within a short turnaround time.
