      I'm working on a video series where I teach the Bala2 Fire to balance using AI (instead of a PID loop). To do that, I am creating a simple model of the Bala2 Fire in FreeCAD and importing it into the MuJoCo simulator. Part of that process involves specifying the exact location IMU inside the chassis (required to train the balancing agent). However, I cannot find where that IMU is on the PCB.

      It's notably absent in the Bala2 controller PCB (the footprint is empty and the schematic says "DNP" for the MPU6886). I tried to find it in the M5Stack Fire body, and it does not seem to exist. The schematic does not show it, and I can't find any such chip on the PCB (which included disassembling the M5Stack Fire to look at both sides of the PCB).

      The docs say that there is an MPU6886 in the M5Stack Fire somewhere but does not specify where. Does anyone know where the IMU is located in the M5Stack Fire?

        Hello @ShawnHymel

        IMU is on the topside of the board. See here.

        Thanks
