STLink Ninebot Max ESC

In the case of a bricked ESC/Controller/Control Board, STLinking can save the controller from needing to be replaced in some instances.

For this process you will need:

• Windows computer

• STLink (Decent quality clones will work)

• Tools to disassemble the scooter and access the ESC

• Dupont male/female jumper cables

This process can be dangerous if done incorrectly so take caution when performing these steps and make sure you use a computer you are comfortable possibly destroying.

If you short a battery line you could end up blowing up your STLink, Computer, and more or even causing a fire.
