Perhaps a better name would be RPi Boards, CSI Boards are designed to work with the 15-pin Camera Serial Interface Type 2 (CSI-2), most commonly found on the Raspberry Pi system boards. This interface is also found on other systems, such as Raspberry Pi Compute Modules, BeagleBoard Black and Nvidia Jetson Nano, but they are not always compatible (see the MIPI Boards category for boards that are)
