Now you can build a more powerful and flexible voice product that integrates devices for Amazon Amazona voice service, Google Assistant, Baidu AI, etc.\u003cbr\u003e\u003cbr\u003eThe board is an audio module designed based on that for Raspberry Pi. It uses the WM8960 low-power stereo codec, which is controlled by the I2C interface, and the audio is transmitted through the I2S interface. There are two microphones on both sides of the circuit board to collect sound. It also provides 12 APA102 RGB LEDs and an onboard speaker, and provides a user button and an I2C interface for expanding applications.\u003cbr\u003e\u003cbr\u003eIn addition, the on-board 3.5mm audio jack or 2.0 speaker output for JST can be used for audio output, and music can be played through an external headset, and it can also be played with an external speaker through the dual-channel speaker interface. There is a high-quality MEMS silicon microphone on the left and right sides of the board, which can record in stereo.\u003cbr\u003e\u003cb\u003e\u003cbr\u003eFeatures:\u003c\/b\u003e\u003cbr\u003e- Supply voltage: 5V\u003cbr\u003e- Logic voltage: 3.3V\u003cbr\u003e- Audio codec chip: WM8960\u003cbr\u003e- Control interface: I2C\u003cbr\u003e- Audio interface: I2S\u003cbr\u003e- Expansion interface: 1 x I2C, 1 x button\u003cbr\u003e- Power interface: 1 x Type-C interface (5V)\u003cbr\u003e- LED interface: 12 APA102 programmable RGB LEDs, connected to SPI interface\u003cbr\u003e- DAC SNR: 98dB\u003cbr\u003e- ADC SNR 94dB\u003cbr\u003e- Headphone driver: 40mW (16Ω at 3.3V)\u003cbr\u003e- Speaker driver: 1W per channel (8Ω BTL) (onboard mono speaker)\u003cbr\u003e\u003cbr\u003e\u003cb\u003eProduct Specifications:\u003c\/b\u003e\u003cbr\u003e- Working voltage: 5V\u003cbr\u003e- Interface: I2S\u003cbr\u003e- Size: 65 x 56 x 21mm\u003cbr\u003e\u003cbr\u003e\u003cb\u003eProduct Interfaces Introduction:\u003c\/b\u003e\u003cbr\u003eLP and LN correspond to the positive and negative poles of left speaker respectively; RP and RN correspond to the positive and negative poles of right speaker respectively.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eFunction Pin         Pin For Raspberry Pi (BCM)                         Description\u003c\/b\u003e\u003cbr\u003e5V                                          5V                                      Power supply positive (5V power supply input)\u003cbr\u003eGND                                     GND                                         Power supply ground\u003cbr\u003eSDA                                   P2\/SDA                                           I2C data input\u003cbr\u003eSCL                                    P2\/SDA                                          I2C clock input\u003cbr\u003eCLK                                       P18                                            I2S bit clock input\u003cbr\u003eLRCLK                                   P19                                           I2S frame clock input\u003cbr\u003eDAC                                      P21                                           I2S serial data output\u003cbr\u003eADC                                      P20                                            I2S serial data input\u003cbr\u003eBUTTON                            P29 or P31                                         custom buttons\u003cbr\u003e\u003cbr\u003e\u003cb\u003eProduct Using:\u003c\/b\u003e\u003cbr\u003e\u003ca href=\"http:\/\/ukonline2000.com\/?p=1207\"\u003ehttp:\/\/ukonline2000.com\/?p=1207\u003c\/a\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003ePackage Included:\u003c\/b\u003e\u003cbr\u003e- 1 x Raspi Voice HAT\u003cbr\u003e\u003c\/p\u003e","brand":"Thanksbuyer","offers":[{"title":"Default Title","offer_id":40826637975601,"sku":"69787","price":32.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0578\/4790\/6353\/files\/7077563105329_watermarked_0.jpg_0.png?v=1767865236","url":"https:\/\/www.thanksbuyer.com\/cs\/products\/raspi-voice-hat-dual-microphone-expansion-board-for-ai-voice-applications-for-raspberry-pi-4b","provider":"Thanksbuyer Online,SDR Radio, Testers and Measurement devices, Astronomy products,  Audio Amplifer and Decoders","version":"1.0","type":"link"}
