Securing the Speed Controller
There are two securing grooves on either side of the speed controller. The grooves have a
diameter of 2 mm, and it is recommended to use M2 screws. The heat-shrink tubing must be
cut in order for the M2 screws to pass through the grooves. DJI bears no responsibility for any
damage caused to the heat-shrink tubing when it is cut.
Using RoboMaster Assistant
To congure the speed controller or update its rmware, use a Takyon Updater or a compatible
USB-to-serial converter via RoboMaster Assistant.
The voltage of the USB-to-serial converter must be 3.3 V.
