Is there diffrients between servo 1-4 and orther servo port?

[admired]

Today I met a strange thing, I have a DC motor pushrod, when changing the power supply ± will be positive and reverse, I use a DC ESC connected to SERVO1-4, can control the pushrod motor positive and reverse, but when I connect to the other port, even though I set the SERVO port RCPASS, I can see the change of PWM value in SERVO output, but the pushrod motor does not move. Is it that the 1-4 port is special? How should other ports be set to have output?

im using a qiotek h743 fm ROVE4.4.0 newest mp

Hi @admired,

The only thing I can imagine is that some outputs are grouped because the hardware shares timers or other settings. On many of our autopilot wiki pages we have some information on the hardware pin grouping.

I don’t see the grouping on the qiotek h743 page but here’s another autopilot page that does have it.
