Confusion about IMU coordinate frame

Hemang-Flo

Hi How is the IMU coordinate frames is directed compared to traditional Robotics world frame ? There are docs out there and answers but is the coorindate frame of IMU universal across all models or it differs from version to version ? We're using Oak-D camera 249$ version. I Wanted to know if the IMU coordinate frame has x downwards, y to the right and z backward compared to traditional roboics world or body frame where x is forward, y to the left and and z upward ? I found the IMU coordinate mentioned here from one of the answers from Luxonis forum

Z should be forward/back, X is horizontal, Y is vertical. The orientation depends on how the IMU was placed on the PCB (pcb space concerns). You can rotate it in postprocessing.
