Mic click carries the SPQ0410HR5H-B surface mount silicon microphone with maximum RF protection.
The click is designed to run on a 3.3V power supply. It communicates with the target microcontroller over the AN pin on the mikroBUS™ line.
Smart Mic Click is a compact add-on board that provides wake-on-voice capabilities with secured privacy without compromising performance. This board features the IA611, an “Always-On” voice-wake acoustic processor from Knowles Electronics. The IA611 offers flexibility by supporting the most relevant audio and data interfaces and enables ultra-low-power voice and event detection, including voice UI supporting keywords, voice commands, and acoustic event detection. Its integrated programmable DSP is made available to 3rd party algorithms with 168kB of RAM, enabling unlimited creativity. This Click board™ represents an ideal solution to add a voice-enabled VUI or event detection into IoT products such as home sensors, appliances, lifestyle control devices, and security systems.
Smart Mic Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
