A functioning IMU is essential to the BorgCube because I intend to use it to maintain the craft's balance. However, the IMU I'm using will often loose calibration at unexpected moments. Oddly this is particularly prone to happen when I turn on the lights! Looking over my PCB design, the 12V track which powers the lights passes within 10mm of the IMU. I haven't seen any design notes from Bosch regarding device placement, but it seems that this is too close.

More experimentation is required, but I intend a place an addition IMU in the forward capsule containing the cameras. We'll see how they do working together.
