Analog and Digital Output Separate pins for analog and digital output, with the default output set to analog, enabling versatile connectivity for a range of circuits and sensors. Professional Sound Quality Uses a professional microphone amplification IC to deliver enhanced sound quality and low output noise for clearer audio capture. Easy Integration A well-designed microphone amplifier that is easy to integrate, helping to improve audio performance in electronics projects with minimal setup. Dual Power Supply Supports 3.3V and 5V power supplies, providing flexibility in powering your projects and matching common microcontroller and SBC systems. Use scenarios - Microcontroller projects (Arduino, ESP32, etc) that require clear microphone input via analog output or optional digital signaling. - Voice sensing and command applications in DIY devices or robots, where low noise and reliable audio capture improve performance. - Audio input for single-board computers (Raspberry Pi, etc) for simple voice capture, sound-triggered actions, or basic recording.
