The module programs internal flash of a micro-controller. Location and type of the chip:
- in P3X and P3S, it is STM32F407 on WM320 Gimbal top board
- in P3C and P3XW, it is STM32F407 on WM321 Gimbal top board
- in P4, it is STM32F303 on WM330 Gimbal Master Control board
- in Mavic, it is STM32F303 on WM220 Gimbal Sensor Control board
- in other products, the location is unknown
Gimbal master control. The programming is responsible of getting data from sensor and user commands from the internal bus, then using this information to properly drive three gimbal arms: yaw, roll and pitch. Each of these arms contains its own micro-controller, connected to gimbal master control via serial interface. The arm controllers are sharing status information using the same serial interface.
There are multiple versions, unencrypted for most products, but for P3 usually encrypted.

The module is usually unencrypted, but there are encrypted versions too.
The unencrypted firmware is a memory image of ARM binary. During startup, it is being loaded into memory at constant address and executed by a loader. Such memory images are usually prepared by first linking the file with all libraries, and then using objcopy -O binary to get the final file without ELF header. The ELF header can be re-created if the address and boundaries of sections are known.
Base address is:
- 0x08008000 in P3X and P3S
No analysis of the booting procedure were performed.
