On ASK AN ENGINEER, our founder \u0026amp; engineer chatted with Pete Warden, the technical lead of the mobile, embedded TensorFlow Group on Google’s Brain team about what would be ideal for a board like this.\u003c\/p\u003e\n\u003cp\u003eAnd here’s what we designed! The BrainCraft HAT has a 240 x 240 TFT IPS display for inference output, slots for camera connector cable for imaging projects, a 5-way joystick, button for UI input, left and right microphones, stereo headphone out, stereo 1 W speaker out, three RGB DotStar LEDs, two 3 pin \u003ca href=\"\/zh\/search?q=stemma+qt+cable\u0026amp;narrow_by=\u0026amp;sort_by=relevency\u0026amp;page=1\"\u003eSTEMMA connectors\u003c\/a\u003e on PWM pins so they can drive \u003ca href=\"\/zh\/collections\/adafruit-neopixels\"\u003eNeoPixels\u003c\/a\u003e or \u003ca href=\"\/zh\/collections\/servos\"\u003eservos\u003c\/a\u003e, and Grove\/STEMMA\/Qwiic I2C port. This will let people build a wide range of audio\/video AI projects while also allowing easy plug-ins of sensors and robotics!\u003c\/p\u003e\n\u003cp\u003eA controllable mini fan attaches to the bottom and can be used to keep your Raspberry Pi 4 cool (untested for size with Pi 5) while doing intense AI inference calculations. Most importantly, there’s an On\/Off switch that will completely disable the audio codec, so that when it's off there’s no way it's listening to you.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1.54\" IPS TFT display with 240 x 240 resolution that can show text or video\u003c\/li\u003e\n\u003cli\u003eStereo speaker ports for audio playback - either text-to-speech, alerts or for creating a voice assistant.\u003c\/li\u003e\n\u003cli\u003eStereo headphones are out for audio playback through a stereo system, headphones, or powered speakers.\u003c\/li\u003e\n\u003cli\u003eStereo microphone input - perfect for making your very own smart home assistants\u003c\/li\u003e\n\u003cli\u003eTwo 3-pin JST STEMMA connectors that can be used to \u003ca href=\"\/zh\/products\/stemma-wired-tactile-push-button-pack-5-color-pack\"\u003econnect more buttons\u003c\/a\u003e, a relay, or even some \u003ca href=\"\/zh\/products\/adafruit-neopixel-led-strip-with-3-pin-jst-connector-ada3919\"\u003eNeoPixels\u003c\/a\u003e!\u003c\/li\u003e\n\u003cli\u003eSTEMMA QT plug-and-play I2C port can be used with any of our 50+ I2C STEMMA QT boards or can be used to connect to Grove I2C devices with an adapter cable.\u003c\/li\u003e\n\u003cli\u003e5-Way Joystick + Button for user interface and control.\u003c\/li\u003e\n\u003cli\u003eThree RGB DotStar LEDs for colourful LED feedback.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe STEMMA QT port means you can attach heat image sensors like the \u003ca href=\"\/zh\/products\/adafruit-amg8833-ir-thermal-camera-breakout\"\u003ePanasonic Grid-EYE\u003c\/a\u003e or \u003ca href=\"\/zh\/search?q=mlx90640\u0026amp;narrow_by=\u0026amp;sort_by=relevency\u0026amp;page=1\"\u003eMLX90640\u003c\/a\u003e.
