Hello everyone,
I bought a DJI E300 pack and I am providing the PWM signal to ESCs with my Raspberry Pi 3.

I have a 16 channel PCA9685 PWM driver which is connected to the Pi via I2C (I just wanted to mention that I'm not using software PWM).

My problem is that the starting value that makes the motors turn are different, also motors turn with different speed with the same signal. As far as I searched DJI Opto ESCs do not support calibration. How can I solve the problem?

Thanks

Hi, I'm wondering if you ever solved your problem?  I'm trying something similar with a different MCU running my own flight controller.  Also struggling to determine if the ESCs need any specific startup sequence.
