There are a number of sensors and cameras that you can connect to your board.
The reference image runs on the following Renesas R-Car H3 Starter Kit Premier, which is simply known as R-Car H3 Starter.
You can also use the ADAS View Solution Kit from Renesas. This kit includes the R-Car H3 Starter that's already connected to the extension board with four AMI MINICube RDACM21 cameras.
The R-Car H3 Starter board can be connected to multiple cameras and sensors. To connect the cameras, the default configuration uses four (up to eight) AMI MINICube RDACM21 cameras (sensor camers) that are attached to the ADAS View Solution Kit. Alternatively, you can also use GigE Vision compliant cameras or USB cameras. For USB, the board supports only USB 2.0 speeds so you'll be limited to 720p resolution at 10 frames per second.
