AIY Vision Kit is designed to work with a 5V 2A DC power supply with micro USB connector. We recommend the Raspberry Pi Power Supply (https://www.raspberrypi.org/products/raspberry-pi-universal-power-supply/). A power supply with less than a 2A rating will cause to the system to behave improperly.
Raspberry Pi Board
AIY Vision Kit is designed to work with Raspberry Pi Zero W (version 1.1) and Raspberry Pi Zero (version 1.3). Please note the AIY Vision Kit requires the Raspberry Pi board to have a camera connector.
To find out which version of Raspberry Pi Zero you have, log into your system and type the following command:
cat /proc/cpuinfo | grep Revision
||Pi Zero without camera connector, no wireless
||Pi Zero with camera connector, no wireless
||Pi Zero W with camera connector + Wi-Fi/Bluetooth
Raspberry Pi Camera
AIY Vision Kit is designed to work with Raspberry Pi Camera Module Version 2. Please note that Camera Module Version 1 is not supported and will not work. The Raspberry Pi Camera Module Version 2 NoIR will technically work (it uses the same sensor), however our ISP is not optimized for this unit.
Raspberry Pi Camera based applications perform best when run one at a time. The AIY Vision Kit enables the Joy Demo application by default. To experiment with other Raspberry Pi Camera based applications, you must disable or stop the Joy Demo by using the following commands:
sudo systemctl stop joy_detection_demo.service
sudo systemctl disable joy_detection_demo.service
Flex Cable Connections
Be sure to check both flex cable connections. The device will not boot if the cables are connected incorrectly.
IMPORTANT: Ignore the white sticker that says “PI” or “VisionBonnet” on the MIPI flex cable. These may be incorrectly applied.
Find the silkscreen serial number on the MIPI flex cable and orient it so the numbers are facing you. With this orientation, the right side of the flex cable connects to the VisionBonnet and the left side to the Raspberry Pi board.
SD Card Image
The Vision Kit SD image is designed to work with both the Vision and the Voice Kit. It is normal to see references to the Voice Kit in the image.
If you intend to use the Vision Kit image on your Voice Kit, you need to edit boot/config.txt and uncomment this line at the bottom of the file:
You can run this command to check that the Vision Bonnet is connected and has booted successfully:
dmesg | grep googlevisionbonnet
If it has, you should see output similar to this:
