Connecting two Grove - Vision AI Module V2 (or any two cameras) to NyBoard

Is it possible to connect two of these to the Nyboard directly? It seems like there's only one I2C socket and that would be the only way to connect this module. If only one can be connected, is there any other way someone has found to connect any two cameras to the Nyboard? I would like to avoid having to setup up a raspberry pi just to connect two cameras that I will be streaming to another PC. My plan is to process the feed and send actions to the robot wireless. I am currently in the investigation phase of whether this is viable to begin with and what hardware I would need. Will appreciate any insight, thanks.

I want to provide some updates for anyone looking in the future: It is possible to power both Mu3 from the digital grove connectors on the NyBoard. It is also possible to configure them to the wifi router and password using AT commands sent using SoftwareSerial on an ino script (when they are set to the image transmission mode).

I saw your email. The Mu camera can be set to different I2C addresses. The Vision AI module V2 has a fixed I2C address. Regarding the video streaming function, neither board would required the computational power on NyBoard. Mu3 will use its onboard ESP32 to stream via WiFi. The Vision AI module will also need ESP32 to stream. Our BiBoard, or Seeed's Xiao board, are both based on ESP32.

Thanks for answering. So there's no concern with the computational power on the NyBoard if I use the MU. I take it this also means I can use digital grove connectors to power the cameras from the NyBoard then?

I don't know if the NyBoard has enough processing power for your dual camera robot project. The BiBoard may be a better choice (see https://www.petoi.camp/forum/general-discussions/my-board-your-board-let-s-talk-about-ny-and-bi-boards).

However, regarding the physical connection, you could use an I2C hub if the two camera modules have different (or selectable) I2C addresses (e.g. see https://store.arduino.cc/products/grove-i2c ).

If they have the same I2C address that cannot be changed, you could use an I2C multiplexer (e.g. see https://soldered.com/product/i2c-multiplexer-tca9548a-breakout/).

I am doing something similar (not with cameras but with other sensors sending wireless telemetry to my "laptop as Bittle brain") so you may also be interested in this post: https://www.petoi.camp/forum/clinic/solved-in-search-of-reliable-bidirectional-bluetooth-serial-port-profile-spp-communication

Hope that helps! Your project sounds interesting so please keep us posted on your progress! 😎

Well, the idea would be to beam the video to another pc and not run any vision software on the NyBoard. My concern is more whether I can power and connect both 'Grove - Vision AI Module V2' from the NyBoard using the I2C hub or two 'Intelligent Camera Module for Arduino by Petoi'. So far these are the two camera options I am considering.

I was going through the documentation of the MU camera once more (https://docs.petoi.com/extensible-modules/mu-camera ) and read that its detection result can be transmitted through the UART or I2C interface. This seems to imply that I can power one camera though the I2C grove and the other one through a digital grove on the NyBoard. Then I can use the capability it has to stream video through wifi.
