I don’t know how ti do a better scheme.
If you have a shortcut it save the battery ViFly ShortSaver is the smoke stopper you always wanted - YouTube
Think of it as a vertical drone that can rotate 90 degrees
Reading your OP leaves little hope that you will be
able to do this:
1: Your schematic clearing suggests you have no
electronics experience.
2. You appear to not grasp the complexity of a drone. Your only chance is using an off the shelf
flight stabilization unit:
3. There's nothing in your OP that gives hope that
you can do this.
It begs the question "What EXACTLY ARE your
qualifications to do this ?"
Our job is to help newbies do arduino projects,
not teach people how to flap their arms and fly.
We have an obligation to be truthful.
If you have 'the right stuff' , now would be a good
time to reveal your qualifications, which , thus
far, are not evident. ("I don't know how to .control 2 servos") This is the simplest thing to do using
the Servo() library. The fact that think you
only need to control 2 servos is a huge red flag.
Drones don't even have servos. You apparently
are not familiar with the functional signal names
of the Flight Controller input and output signals.
(there's 4 signals, not 2)
For starters, to be blunt, your schematic is a disaster. When told why, you completely IGNORED my comment pointing out that the ESC
output wires would destroy an ESP32 if connected as shown. What s coincidence !
Read your post title ! You didn't even know the
proper functional name for the output wires that
normally go to the motor. Instead of referring
to them as 'the 3-phase output wires, (that normally connect to the 3-phase motor windings).
Instead you refer to them as 'the colored wires'.
I told you WHY your ESP32 burned up and you
ignored my post ! How can we possibly believe
there is any chance you can do this ? Do you
not see the importance of knowing electronics
to do this ? Where is the evidence that you know
even the most basic electronics concepts ?
Prove me wrong. Show us what you know.
Give us something to work with.

Uh Wow! Very clear statement.
I second this 200%.
Still - every journey regardless of the distance starts with the first step. But indeed to give you advice what kind of equipment would be a good choice for the next part of the journey
Show us what you know.
Are you familiar with Ohm's Law?
Do you know what the Kirchhoffsche rules are?
What was your last electronics or microcontroller-project you did before you started this project?
best regards Stefan
I have not ignored any of the messages that have arrived and I thank everyone for their help. Yes, I have no qualifications in electronics or drones. The knowledge of electronics are only the basics that I studied in the first years of high school (I do computer science, not electronics). I inquired about drones (esc, brushless, battery, etc.). I believe you have misunderstood what I want to do: I don't want to make a drone, I am developing a prototype of a project, the prototype simply rises and rotates 90 degrees (when you fall you do the same thing) and I don't have to make it go on or back. For this I need servomotors (at least in the first prototype). I don't think a flight controller can be useful because it works for drones that are horizontal (my prototype is both horizontal and vertical). Ok you said connecting the power out cables to the esc would burn, but if I started this conversation it's because it happened, not because I didn't listen to you. I do not require you to explain the deeper details to me, but only what the problem is and how I could solve it (as you have already done by saying to buy a bec). I certainly do not reject some advice such as using an external bec.
I love drones, when I was little I had some, but I'm not in the trade (I study programming) and I don't do it as a hobby. I just have a project and I just need to make some prototypes.
Yes, I studied it in electronics ([V / I] if I remember correctly). It is used to calculate the resistance, but I don't know what to do with it.
I did some projects always in electronics such as controlling some LEDs (only in simulation) and I was the best in the class (for the COVID-19 we cannot continue). By myself I simply commanded a servo via a PS4 controller (made for this project).
Do you know WHY connecting HV 3-phase ESC outputs to a 3.3V ESP32 will not end well?
Yeah, because the voltage was at 22.5 and the esp can support max 12V. With a bec I can resolve the problem.
So I’m trying to test if all is ok (I hope).
I.E. Nothing
OP- You have to provide a real schematic. Schematics are how engineers communicate. Pictures are not schematics. You use a pencil and paper. Draw box for each component. Draw a line between the boxes representing connections and label the connections at each end. Use functional labels like L1, L2. Not "Red wire", "Blue wire". If you don't know the functional label, look it up in the component's data sheet.
To keep everyone from going off in a completely separate direction, tell us what your project is. Not, "something like a vertical drone". From your descriptions, we have no idea if your project is supposed to fly or burrow underground. (If it's supposed to fly then from your description it will also burrow into the ground on the first flight).
I could have taken a picture and you would have noticed that they are identical
That is NOT what I said.
I said that theESC HV motor power outcanles shown connected to the 3.3VESP32 and referred to as 'the colored wires' have high voltage on the and would destroy the ESP32 . The BEC is a
completely separate and different issue. You
have STILL not understood what youdid wrong.
You'retalking about the BEC instead of 'the colored wires' , as you called them.
Howare we going to make anyprogress when we have to explain everythingseveral times ?
Stick to S/W.
"They" what?
The three wires to the motor? They are labeled "A", "B" and "C", or sometimes "Phase A", "Phase B" and "Phase C". Consult the motor or the ESP manufacturers specs. The reason they are all the same color is because for hobbyists, it doesn't matter how they are connected to the ESC. If the motor runs backwards, then swap any two wires. But, for a schematic they should be labeled. If they are all black, then pick any three labels at random. You can use "X", "Y", "Z", or "Fred", "John", "Mark". It doesn't matter, just label the wires.
It's obvious the OP has no clue.
but sorry those aren't input pins?
Ok I'm sorry if I'm not clear. I say that the graph of the whole circuit was identical to the real circuit. I don't understand why you're focusing on engines.
Because of your FIRST post:
On a drone the ESC controls a three-phase brushless motor. Since you said it's a drone project, and you are using an ESC, it must be connected to a motor.
I am not talking about the ESP32!Vin . I am talking about 3-phase motor POWER (HV) ('COLORED')
wires shown connected DIRECTLY to the ESP32 !
How many times to I have to explain this ?
Ok, but it is connected with a single cable to the esp (one per motor) and is controlled as a servomotor.
As I already told SteveMann, the pins / cables or whatever you want to call them, are not power. They are 4 wires (one for each motor) and are connected to the esp for control.
I'm sorry if you are angry and, if you're thinking I'm stupid... You're right
AGAIN, flying drones do not use servo motors.
They use 3-phase brushless motors.
The servo driver board shown is not shown in your original diagram and is useless fordriving
brushless motors. You keep talking about servo
motors which ate useless for flying objects , no matter what you call it. You need to start by learning RC and then learn electronics. Everything
we are say is GREEK to you.
