Upgraded 6+1 Mic Array Speech Recognition Array with RGB Full-Color LED I2S for Audio Source Localization Beamforming

The 6+1 Microphone Array Module ( Model) features seven silicon microphones and twelve programmable full-color LEDs, making it suitable for applications such as voice capture, sound source localization, and full-color LED display. Silicon Microphone Specifications: 1. Onboard: 6+1 SI4030B261-CJ01 silicon microphones; supports Left and Right channel output. Configuration: 3 Left-channel Mics (M0/M2/M4) + 3 Right-channel Mics (M1/M3/M5) + 1 Right-channel Mic (M6). 2. Communication Interface: I2S 3. Sound Pressure Level (SPL): 120 dB 4. Sensitivity: -26 dB (dBFS @ 1 kHz, 1 Pa) 5. Signal-to-Noise Ratio (SNR): 63 dB (20 kHz bandwidth, A-weighted) 6. THD: <1% (100 dB SPL @ 1 kHz; S = NOM, RLOAD > 2 kΩ) 7. Clock Frequency: 1.0-4.0 MHz (Normal Mode); 150-800 kHz (Low-Power Mode) Ring LED Specifications: 1. Features 12 onboard, cascaded SK9822 full-color LEDs with integrated ICs; requires only 2 MCU I/O pins for control. 2. Communication Interface: Two-wire synchronous control signals (CKI and SDI). 3. Viewing Angle: 120 degrees. 4. Two-wire synchronous control supports selectable positive or negative output for the RGB tri-color LEDs. 5. 8-bit (256-level) color setting; 5-bit (32-level) brightness adjustment. 6. Current Consumption: 20 mA per LED per color channel; 60 mA per LED at maximum brightness (full color).
