Hi @JIHOON, welcome to the forum 🙂

What code are you running, and how have you set up/connected your power supply, Raspberry Pi, ESCs, and thrusters? If you explain/show what you’ve tried so far then we can try to help you determine which components aren’t set up correctly or need to be changed 🙂

The `RPi.GPIO` library may not be precise enough to correctly run our ESCs, so it’s suggested to use a hardware-focused library like PiGPIO. See this post for details:

The issue was that the ordinary PWM library “RPi” used with the Raspberry Pi uses software PWM, which doesn’t have the accuracy to deliver that initialization pulse width. A library called PIGPIO uses hardware PWM and drives the Basic ESC perfectly though. Thanks for the support, Andrew

If you’re interested in a more abstracted library you can use GPIOZero around PiGPIO, as I discuss in [this comment](https://discuss.bluerobotics.com/t/current-and-pwm-piloting-t200/9913/2), but it’s not a requirement.
