There are 2 types of IMU modules which the STorM32 v1.3x 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 between the two types of IMUs [[1]], and this post to identify your IMU [[2]].

The STorM32 v3.x controllers can only use NT IMUs, not I2C IMUs.

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 IMU. If you do not know what a NT IMU is, then you likely have a I2C IMU and need firmware v0.96.
