Matek F722 + Betaflight


Sure I will chase that up for you today, worst case you can always return it back to us for testing/repairs and if we can’t fix we will replace it assuming but is still under warranty (within 180 days of purchase)


Thanks alot, Bought it on 2nd October.


Hello everyone,

Just to make sure, do I need to connect power, escs and everything before connecting to pc?
The following forum has a topic on this issue and says that fc wont work unless it gets powerd from lipo.

You think this might be an issue?
Also it says in Betaflight 3.4.0 it is working fine without battery.

I dont want to plug the lipo and usb at the same time as I might fry the board… so need a little advice on this. unmannedtech asked to return but one more try before that. I might run into same problem with another f722 :smile:


give it ago…

Powering the FC by USB and Lipo at the same time shouldn’t hurt it at all.
Powering by Lipo is the only way to activate the ESCs so they can be calibrated.


OMG I just had a intense moment with this Matek fc :smile: :blush:
I was thinking of trying both lipo and usb but before that I had a random thought of trying another usb cable laying around (it’s a fast charging cable) and it made the usb connection sound in windows.
I tried 2 cables but may be they are not speed enough? idk
It works fine now. Thanks for the help everyone. Then I pluged the default cable and it don’t work. idk why it didn’t work with the other usb cable I tried.

I just flashed the recent firmware and feels gooooood :smiley:


there are two types of usb cables…
power and data

you may have been using a power cable they look the same.

well done in finding your problem and moving forwards


Does anyone know what does led and buzzer port mean in matek f722? is it a power port or a signal port that can be controlled using radio? Like a servo?


talking about the bottom left six holes now, the G 5v and LED on top are for programmable RGB led lights, eg blue disarm red arm, needs to be turned on in config then programmed through led tab.
painless 360 as a good instruction video here
Bottom row S3 is for motor 3 signal 5v and buz are to attach a pietzo buzzer that sounds when aircraft lost, low battery etc can be switch on off from radio by switch but must config in modes tab.

It says there is 8 motor support but i only see 7 which including the pwm pad. Anyone know where is the motor 8? How do I actually find out what ports are those codes for example, A02, B02, A00, A01…

you will notice A02 motor 8 is also serial tx2. these are resources the board uses as outputs and inputs.
it is possible to reassign any resource to most pads.
you seam to have a few problems with FC and firmware so being honest i would suggest you leave alone.
you cannot damage it, if you mess it up all that is required is a re-flash and all back to normal.
if you have an old FC practice moving motor outputs to different pads, this is very useful if after a crash a pad gets pulled of.
