If you can't find the com port, you need to download and install Ch340 or Ch341 driver. Connect the computer and ESC signal cable with Usb, click Tools, select com port, click Connect, then power on the ESC, confirm the connection is successful, then Readpara to read the parameters, then modify the corresponding parameters, then click writepara to write and save.


PWM full name is (Pulse-width modulation). It is also called duty cycle signal, which indicates the proportion of the high level duration to the whole signal period. 2ms for the whole period of PWM, 1.5ms stop, 1.5-2ms forward, 1.5-1ms reverse.

From the diagram, we can clearly see that when PWM is 75% (1.5ms), the motor stops rotating, when PWM is 50% (1ms), the motor rotates in reverse, and when PWM is 100% (2ms) the motor rotates in forward.Of course ESC will not only make the motor turn forward and reverse, but can adjust the speed of motor rotation by the duty cycle size of PWM. When the PWM is gradually changed from 75% to 50%, the motor will keep reversing and accelerating from stop until the reverse rotation reaches the maximum. And when PWM is gradually changed from 75% to 100%, the motor is continuously accelerated from stop to forward until the forward rotation reaches the maximum value. That is, PWM is a signal that can be continuously varied, and the effective range is from 50% to 100%.

The frequency of PWM signal is 50hz, 100hz, 200hz or 500hz, etc. The higher the control frequency, the shorter the period, the shorter the control interval, and the faster the ESC and motor response speed The faster the ESC and motor response. Conversely, the lower the control frequency, the longer the period, the longer the control interval, and the slower the ESC and motor response.

Great thrusters

Im using the thrusters as stern thrusters on my 18’ fishing boat. I use livescope and spot lock to hold over fish but the wind or currents blow the stern around.Now I can hold an exact spot and fish it all day without moving. Works Great!!
