Power up your VESC® motor controller and connect it to your computer using a USB cable.

Some cheap micro USB cables are designed for charging your
phone and will not work properly! Try another cable if you experience any issues.

Run the VESC®-Tool software.



Click on firmware in the left menu bar. This will bring you to the screen shown below.

Make sure to select the correct Hardware! Wrong firmware will instantly and permanently damage your hardware
when you try to operate it.
