Microphone Unit (LM393)

Unit MIC is a sound sensor equipped with an omnidirectional electret microphone. The signal is amplified and output through the MAX4466 microphone preamplifier. This amplifier effectively suppresses power supply noise and common-mode noise, providing high-fidelity sound output, making it suitable for use in noisy environments. This unit can output both analog and digital signals. It includes a built-in LM393 dual voltage comparator, allowing the comparison voltage threshold to be set by… (M5Stack U096)
