I2S Microphone Module

This high-sensitivity single microphone module utilizes the MSM261S4030H0 digital silicon chip, offering an I2S output and an onboard SK9822 series RGB LED for two-wire control color. The MSM261S4030H0 is an omnidirectional, bottom ported, I2S digital output MEMS microphone chip, simplifying your audio signal processing with ease.

In typical audio systems, microphones convert audio signals into analog voltages, which are then processed by main controllers after digital conversion through codecs. However, the MSM261S4030H0 series features a built-in 24-bit I2S audio port, enabling direct digital signal output to the main controller without the need for an extra codec. This reduction in signal chain complexity significantly decreases size, cost, power consumption, and interference susceptibility.

With personal portable electronic products gaining traction in the consumer market, the advantages of silicon-based microphones such as high production repeatability, excellent sound quality, and scalability are becoming increasingly apparent. Combining semiconductor technology benefits, this product exemplifies the superior value and performance of MEMS microphones, poised to supplant traditional electret condenser microphones in the near future.
