6+1 microphone voice recognition array I2S interface Ring full color built-in IC LED, Sound source localization K210 development board fitting .

Overview :

LC 6+1 Mic Array module carry 7 high quality Silicon microphone and 12 Programmable full color LED,Can be used for voice recognition capture, sound source localization, LED full color display and other occasions.
Function
1. Silicon microphone parameter：
1.1 onboard 6+1 MSM261S4030H0R Silicon microphone,support right and left channel output，3 left channel MIC(M0/M2/M4)+3right channel MIC(M1/M3/M5)+1 right channel MIC(M6)
1.2 Communication Interface :12s
1.3 Sound pressure level :140db SPL
1.4 level of sensitivity：-26(dB,dBFS @1KHz 1Pa)
1.5 Signal to noise ratio：57dB(20KHz bandwidth, A-weighted)
1.6 HD<1%(100dB SPL @1KHz S=Nom, Rload>2K)
1.7 Clock frequency：1.0-4.0MHz (Normal mode)，150-800KHz （low power mode）

2.1, onboard 12 cascaded SK9822 built-in IC full-color LEDs, which can be controlled by only 2 MCU I / Os;
2.2,Communication interface: two-wire synchronous control signals CKI and SD
2.3, Viewing angle: 120 degrees
2.4, Two-wire synchronous selection of positive or negative output RGB three color LED output.
2.5,each LED each color Consumption current 20mA,Full color maximum current consumption current 60mA .
3. Onboard interface :2.54mm 2*5P Horns/ 2.54mm single pin /0.5mm 10P FPC base.
4. Scope of application: Our K210 Dock development board can also be driven by other MCUs with I2S interface.
