This high sensitivity single microphone module features MSM261S4030H0 digital silicon chip, I2S output, onboard SK9822 series RGB LED,two-wire control color.

MSM26S4030H0 is omnidirectional, bottom ported, I2S digital output MEMS microphone chip. I2S is a general-purpose digital audio interface and widely used in DSPand digital audio processing fields. In a conventional audio system, audio signal collected by the microphone will be converted into analog voltage and output,and then processed by the main controller chip after being changed into digital signal and encoded through the ADC of codec. However, the product of MSM261S4030H0series has built-in 24bit I2S audio port, so without adding extra Codec, it is able to realize full digital signal connections with DSP or MCU. The raw digitalaudio signal is directly output to the main controller chip. As a result, the complexity of designing signal chains will be greatly reduced, which allows the productto hold advantages in size, cost, power consumption, and anti-interference.

Nowadays, personal portable electronic products have been gradually becoming dominant in the consumer market. This kind of silicon-made microphone learns theadvantages of semiconductor technology and combines high repeatability of production, excellent sound performance, and great expansibility. Therefore, it can besaid with confidence that in the near future, the traditional ECM(electret condenser microphone) will be replaced by the low cost and high-performance MEMS.
