I’m want to connect 4 BLHELI_32 DShot 40A ESCs to a Pixhawk 4 (so using the PM07 power board) to power the motors for a quadcopter. Is this currently supported? I’ve been advised that I can just connect the ESC signal and signal ground wires to the FMU rail. But the FMU rail still outputs PWM, and DShot is digital, so I’m skeptical as to whether this will work. I imagine I’d also need to reconfigure the airframe so that the ESCs are no longer on MAIN1-4? Do I still power the ESCs off of the I/O 1-4 outputs on the Power board?
Any answers to the above would be much appreciated.
