Greetings all. I am planning out my second build, and have extensively looked at flight controllers, settling on the Matek H743 Slim. There is a slight issue, however. I plan on using four ESCs, and the wiring diagram only shows a 4-in-1 esc. Is it possible to make this work, or should I look at another flight controller?
Thank you!

Servo (output) signal wires are all available as solder pads. The usual wiring puts Motor1-Motor4 on pins S1-S4:
Yes, it is possible. Wire them like @Yuri_Rage said
Thank you very much for your response.
What about BEC? I see a 5v pad on the board but not a ground, if the pad in the image is what I’d use to replace BEC, what ground G pad do I connect to?
The pad in the image is a solder jumper with 2 positions that determines what voltage is available on the Vsw pad. There are ground pads all over that board. Like the one adjacent to the Vsw pad…
If you just want 5V use a 5V pad. Good for 2A.
In case you’re not aware, most ESCs only need a signal and ground connection. Many ESCs include a 5V BEC which can be used to power other devices. You generally don’t want the 5V from the ESC BEC to be connected to the flight controller’s 5V line. So don’t connect the ESC’s red wire (between the signal and ground wire) to the flight controller. Connecting a 5V power supply (from an ESC’s BEC) to a line which already has 5V on it can (and usually does) cause problems.
Sorry if this is old news. I didn’t want you to make a mistake which is easy to avoid.
If not using that 4in1 ESC, attach your connector to the ESC’s to the FC 8P connector. For other signals (compass, GPS, R/C…) solder row headers, and for others (buzzer…) solder 28AWG silicone wire on the round solder pads.
If I remember well, for the first use with Ardupilot you must use ST programming tool.
Does anyone know which brand and model of 4in1 digital ESC is suitable for Matek H743-Slim/Mini V3 FC? Per Arm 35A max. Light-weight.
I hope to get it stacked, mounting holes and orientation is my concerning.
Will be good if any ESC I should be avoided.
Any comment towards AM32 ESC compatibility with Ardupilot, my guess shouldn’t have any issue, I maybe wrong. Any comments toward this guy comment and compare to BL_heli32. I am exploring flywoo ESC.
I would go with a Skystars AM32 30x30. They have been doing AM32 for a while.
Headache. I am very concerned.
Yea, there seems to be some issues to resolve with AM32. I don’t have one to test.
