4 Mic Input Decoder Module for Raspberry Pi Expansion Board Microphone AC108 Smart Voice Practical Program recognition module

description:
1. Based on RASPBERRY PI 40PIN interface, suitable for RASPBERRY PI series motherboards;
2. Support RASPBERRY PI ZERO/ZERO W/2B/3B/3B+/4 and other development boards;
3. Adopt AC108 low-power stereo codec chip, which can communicate through l2S interface;
4. Onboard 4 high-quality MEMS silicon microphones, which can record left and right channels;
5. Onboard 12 programmable APA-102-2020 full-color LEDs;
6. Power supply mode: plug into the Raspberry Pi to get 5V and 3.3V power;
7. Logic voltage: 3.3V;
8. Raspberry Pi control interface: I2C, audio interface: I2S, the Raspberry Pi controls the microphone array through the I2C interface to capture the voice, and then transmits the voice signal to the Raspberry Pi through the l2S interface, and finally the 3.5MM headphone holder of the Raspberry Pi /HDMI interface output audio;

MIC1--MIC4: 4 analog MEMS silicon microphones;
D1--D12: 12 APA102 full-color LEDs, connected to the SPI interface of the Raspberry Pi;
RASPBERRY PI 2*20P seat: support RASPBERRY PI ZERO/ZEROW/2B/3B/3B+/4 etc.;
AC108: Highly integrated four-channel ADC with I2S/TDM output conversion function;
GPIO12: GROVE digital port, connected to GPIO12 and GPIO13 of Raspberry Pi;
I2C: GROVE l2C interface, connected to l2C-1 of Raspberry Pi.
