Voice Recognition Board AC108 Audio Decoding Module 4 Microphone Audio Sound Card Expansion Board for Raspberry Pi

Feature:

1. Based on RASPBERRY PI 40PIN inter, 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 I2S inter.

4. Onboard 4 high-quality MEMS silicon microphones, can record left and right channels.

5. Onboard 12 programmable APA-102-2020 full-color LEDs.

6. Power supply method: plug into the Raspberry Pi to obtain 5V and 3.3V power.

7. Logic : 3.3V.

8. Raspberry Pi control inter: I2C, audio inter: I2S, the Raspberry Pi controls the microphone array to capture voice through the I2C inter, and then transmits the voice signal to the Raspberry Pi through the I2S inter, and finally the 3.5MM headphone base / HDMI inter output audio.

9. With the Raspberry Pi, you can DIY similar smart speakers out of Genie, Xiaodu speakers, Google assistant.
