There are 2 types of IMU modules which 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.

v0.96 Firmware for I2C IMUs

Firmware for STorM32 setups using a I2C camera IMU. Examples are the HakRC gimbal and other gimbals from Aliexpress.

Latest firmware v0.96 for I2C IMUs:

o323bgc-release-v096-v20160319 [.zip] (9.4MB)

Note: This wiki here is not appropriate for v0.96 I2C setups, you should go to STorM32 v0.xx Wiki.

Comment: The v0.96 release also includes firmwares for NT IMUs, identifiable by a label "nt" in the file names. Don't use them, use the v0.96 firmware (without a "nt" in the file name).
