Description:
I2S Microphone Module This high-sensitivity single microphone module features an MSM261S4030H0 digital silicon chip, I2S output, onboard SK9822 series RGB LED, and a two-wire control color.
MSM26S4030H0 is an omnidirectional, bottom-ported, I2S digital output MEMS microphone chip. I2S is a general-purpose digital audio interface and is widely used in DSP and digital audio processing fields. In a conventional audio system, the 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 MSM261S4030H0 series has a built-in 24bit I2S audio port, so without adding extra Codec, it can realize full digital signal connections with DSP or MCU. The raw digital audio 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 product to hold advantages in size, cost, power consumption, and anti-interference.
