If you do not know how to config WiFi, please google how to setup wifi raspberry piģ- Get the ip address of your raspberry pi, if you do not know how to get the ip address please refer to raspberry offical documentationĤ- Use the ip address to connect the raspberry pi with your PC via putty ssh serve. If you do not know how to open ssh, please google how to setup ssh raspberry piĢ- Your raspberry pi and your PC are working on the same WiFi net. Before started, please make sure:ġ- Open ssh fuction of your pi to let the putty in. You need to use Putty or other ssh tools to connect with your raspberry pi. Connect the Raspberry Pi with the PC via the micro-USB cable Plug the earphone into the 3.5mm headset audio jack or plug the speaker into the JST 2.0 speaker jack Plug the ReSpeaker Voice Accessory HAT into the Raspberry Pi via the 40 Pin GPIO Connect the ReSpeaker Voice Accessory HAT with ReSpeaker 6-Mic circular Array via the Ribbon Cable Sensitivity: -22 dBFS (Omnidirectional)Īctually the ReSpeaker 6-Mic Circular Array support Raspberry Pi Zero, Raspberry Pi 1 B+, Raspberry Pi 2 B, Raspberry Pi 3 B, Raspberry Pi 3 model B+, Raspberry Pi 3 A+ and Raspberry Pi 4 in this wiki we are using Raspberry Pi 3.Compatible with Raspberry Pi 40-pin headers.Raspberry Pi compatible(Support Raspberry Pi Zero and Zero W, Raspberry Pi B+, Raspberry Pi 2 B, Raspberry Pi 3 B, Raspberry Pi 3 B+, Raspberry Pi 3 A+ and Raspberry Pi 4).Rest of 2 input channel are echo channel of Raspberry Pi consists of two boards, one is Is an extension board, aka HAT designed forĪrray kit, comes with six microphones andĭesigned for AI and voice applications. Seeed’s ReSpeaker 6-Mic Circular Array Kit The sensor itself has a native resolution of 5 megapixels and has a fixed focus lens onboard.ReSpeaker 6-Mic Circular Array Kit for Raspberry Pi The ribbon cables are compatible with both the RPi Zero v1.3 and RPi Zero W. This bus travels along the ribbon cable that attaches the camera board to the Pi. The camera is connected to the BCM2835 processor on the RPi via the CSI bus, a higher bandwidth link which carries pixel data from the camera back to the processor. The CSI bus is capable of extremely high data rates, and it exclusively carries pixel data. This interface uses the dedicated CSI interface, which was designed especially for interfacing to cameras. Like the Raspberry Pi camera board, it attaches to your Raspberry Pi Zero v1.3 or Zero W by way of the small socket on the board's edge closest to the "PWR in" port. It has a 160-degree focal angle for a very wide/distorted fisheye effect that's great for security systems or watching a big swath of the living room or roadway. It's about the size of a cell phone camera – the module being just 8.6 x 8.6 mm – with only a 2" cable, so you can create an extra compact and sneaky little spy cam. Luckily, the spy camera for Raspberry Pi Zero is smaller than a thumbnail with a high enough resolution to see people, ghosts, or whatever it is you're looking for. Is your house haunted? Or, rather, are you convinced that your house is haunted but have never been able to prove it since you've never had a camera that integrated with your Raspberry Pi Zero but was still small enough that the ghosts wouldn't notice it?
