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

The Aikri-40X-4LS-1 System on Module (SoM) is powered by Qualcomm® QCS404 SoC, which is designed specifically for smart audio applications. The QCS404 supports features such as Multi-mic Qualcomm® Noise and Echo Cancellation that isolates noisy environments from voice, simultaneous multi-keyword detection to aid voice services like Amazon Alexa and Google assistant, Qualcomm® DDFA™ amplifier technology, Qualcomm® aptX™ audio, and Dolby Atmos. The QCS404 integrates a 64-bit Quad-core Arm Cortex-A53-1.4 GHz CPU and a dedicated high-performance audio DSP with hardware enhancement capable of up to 32 channels of audio post processing. The Aikri-40X-4LS-1 SoM integrates 2×2 11ac Wi-Fi and Bluetooth 5.0 connectivity and supports a mic array, multi-speaker connection via Wi-Fi/BT, and multi-room audio streaming. This production-ready SoM has a Yocto Linux BSP pre-loaded and helps manufacturers easily create complex, feature-rich, and voice-supported smart audio applications such as Smart speakers, Soundbars, Home cinema, Smart assistants, Home Hubs etc.
