<p>I think yes, this is doable. In this diagram you can replace the ESC Motor 1 with your 4 in 1 iflight ESC. Note that you will probably need to redirect the PWM outputs to your 4 in 1 ESC signal inputs.</p>

<p>No, no need to do that. Use a single power output of the power board (it is simpler and in certain cases more reliable).</p>

ok, thank you for the response. So as a follow up question, in this wiring situation you described, would the power management be needed at all? Or could I just wire some of the battery power to a 5v regulator for powering my fc, and the rest directly to the 4 in 1 esc, cutting out the pm07 completely?

Indeed, it might be not needed. That is how I would do it actually: split battery power output: one to 4 in 1 ESC and one to an UBEC to get 5V to power the flight controller.

<p>I have a 4 in 1 iflight esc currently connected to my motors. I am attempting to interface it with my flight controller (Pixhawk 4), which comes with a power module (<a href="https://docs.px4.io/master/en/power_module/holybro_pm07_pixhawk4_power_module.html" rel="noreferrer">https://docs.px4.io/master/en/power_module/holybro_pm07_pixhawk4_power_module.html</a>) in order to provide power to my escs and flight controller. This module has individual power outputs for every motor (each output is supposed to connect to a single esc, while the 4 in 1 esc only has one power input. Could I provide power to the motors by wiring all of the positive outputs together of the power module, and using them as the input to the esc, or would this create issues beyond losing the ability to track the power going to each motor? I am using a quadcopter. Thanks.</p>

# Connecting 4 in 1 esc with power module
