Simplified Product Title: Programmable RGB LED Display K210 Development Board for Voice Recognition and Deep Learning

The 6+1 I2S Microphone Array Module is a versatile device that combines voice recognition, sound source localization, and a programmable RGB LED display. Equipped with 7 high-quality silicon microphones and 12 programmable full-color LEDs, this module offers a range of features for various applications.

The silicon microphones on the board consist of 6+1 MSM261S4030HOR microphones, with 3 left-channel mics (MO/M2/M4) and 3 right-channel mics (M1/M3/M5) plus 1 additional right-channel mic (M6). These microphones support left and right channel output and utilize an I2S communication interface. The sound pressure level is capable of reaching 140dB SPL, with a sensitivity of -26dB (DBFS @ 1KHz 1Pa) and a signal-to-noise ratio of 57dB (20kHz bandwidth, A-weighted). The clock frequency of the microphones can range from 1.0-4.0MHz in normal mode and 150-800kHz in low-power mode.

The programmable RGB LED display on the module is driven by 12 cascaded SK9822 LEDs with built-in ICs. These LEDs can be controlled using a two-wire synchronous control signal (CKI and SDI) and offer a viewing angle of 120 degrees. The RGB LEDs can be set to positive or negative output, and each LED can be individually controlled with 8-bit (256 levels) color settings and 5-bit (32 levels) brightness adjustment. The maximum current consumption for all LEDs at full brightness is 60mA.

The module's compact size of 89.7 x 78.8mm and the use of PCB material in a black color make it a versatile and visually appealing solution.

The 6+1 I2S Microphone Array Module with its voice recognition, sound source localization, and programmable RGB LED display, combined with the K210 development board, provides a powerful platform for various applications, such as voice-controlled systems, smart home devices, and interactive signage.
