There are 2 types of IMU modules which the STorM32 v1.x controllers can use, NT IMUs and I2C IMUs, and there are 2 firmwares which correspond to each type. It is important to choose the correct firmware, otherwise your controller and gimbal will not work. Read this page to understand the difference [[1]], and this post to identify your IMU [[2]].

Since firmware version v0.96, the I2C IMU and NT IMU firmware branches have been split, see [[3]]. Firmwares with version numbers v2.xx refer to the NT branch, not usable for setups with I2C camera IMU. If you don't know what a NT IMU is, then you likely have a I2C IMU and need firmware v0.96.
