ESC Signal Ground: Yes or No? | WHY THE ANSWER IS YES17:19
Should you run the signal ground wire to your ESCs? This question comes up a lot among people who build quadcopters. There are compelling arguments both ways. In this video, I’ll tell you why the answer might be YES.
Joshua BardKahn Academy! Awesome format for explanation of complex,
valuable information. Educating the masses for the good of mankind. You are
a Saint! if you guys watched this, and a hundred previous amazingly useful
videos by Josh – follow me to Patreon NOW! You win Josh, I can’t keep
learning without paying you back anymore. Well done.
great video I think more people getting in to this hobby need to have a
better understanding of what we are doing . Awsome job going to change
you’re name to Professor Bardwell. ?☺ cause I am smarter after watching
Hi Josh, was wondering how to get in contact regarding a product review/
You could have been a teacher. Well done. Thanks!
Every time I watch one of your videos I feel like I have to rebuild my
quad….starting to strip the bolt heads…lol
I have an electronics background and i must say that this is brilliant.
I always tune in for your videos like this.
OM do you think that is also necessary an LC filter to the power input, for
the noise suppression?
Something just occurred to me, do we need to use a ground wire with D-shot
the answer should be ‘Maybe, it depends’
Great explanation. Now I get it. Common ground works great with a simple
circuit like a couple of lights and a couple of switches. But with a FC and
ESCs over time, the dedicated ground now makes perfect sense. Thank you.
awesome video. does this all apply for FC/PDB two in one boards as well? I
ask because there’s a short from ESC signal ground to to FC signal ground
before I even add a signal ground wire. the only difference between the
signal and ground wire in this scenario is the gauge of wire. length and
resistance are identical. what say you in this case?
Instead of all this inductance/capacitance hoopla, I bet it is simply I/R
drop (Ohm’s law) from ESC power ground wire and FC. A lot of ESC use a
wimpy 20 AWG wire and when there is peaks of ~50 amps across this tiny wire
the ESC ground level jumps up, and so does the ESC relative logic high
level. Nothing more, nothing less.
