Hello everyone, I'm İzzet Camcıoğlu,
In this video, I'll try to explain the setup and montage of Apm 2.8.
before passing to calibration of flight card, montage and loading firmware,
let's talk about briefly flight card.
First, on this card, there are outputs and inputs.
There, data which comes from receiver
and there we'll connect the exits.
Here, thing that we should care,
we first connect the motors to output,
which means esc connections.
With these connections, It will control motors.
If we want to connect another servo,
because of the connection speed,
it might be just connections servo.
If you want to connect analog servo,
we should connect there.
However, when we take exit signal of the analog servo from here,
we don't take power supply from there
because current which comes from card, isn't enough to supply a servo.
for this reason, if the esc have bec circuit,
it's from there, by removing JP1, I'll talk about it later on.
You can take from esc bec
or we can provide it by using an extra bec system on drone.
Here the thing that I want to talk about input,
we don't have to attach different cable for each input.
Practical way for that, you've to attach a cable like that,
reason for that is, when getting data from command by signal cable
at the same time, supplying command receiver with the black and red cables.
However, as there is not any necessity for other channels,
we can continue connecting just as signal cables provide transfer,
it means that we can obtain 7 channel transfer with just using 3 cables.
Yes, first cable is vertical to supply power,
I connected in order the others,
important thing is from second channel we should connect white, red and black cables
with same order to command receiver.
Now, let's talk about another subject.
This card's supplying of electricity.
This is very important, if we make a mistake, we can damage it.
There are two ways to supply it.
Let me say that this card starting from there,
with a diode,
it's possible to supply it just in this direction.
I mean that it's not possible to have a feedback by being supplied from there.
Two ways of supplying,
first, we connect esc from there,
there is a little JP1 connection part as you see,
this part makes available to transfer electricity in this module in this direction.
Here, the disadvantage is,
if we supply card with bec circuit of esc ,
card won't have any idea about voltage of battery,
because of this reason, we can't see how much voltage has the battery.
The second way of supplying, attaching a power module,
I suggest that if you attach a power module to there,
in all conditions withdraw JP1 jumper from there.
It doesn't matter whether your Esc has bec circuit or not.
It will already supply all electricity for the card by this power module.
If you attach an extra part to here,
you can supply power by this part's esc bec circuit.
However, if it's attached to there,
esc back circuit are active,
JP1 is attached and power module also it can damage the card.
So, if you use power module, withdraw JP1 module from there.
There is another option even though I don't recommend it,
by leaving JP1 as attached and you can cut the red cables which comes from esc.
However, I don't think that is right.
Instead of this, I approve that withdrawing JP1 is a recyclable option in future.
Now let's come to the ports on the card.
We already talked about power module,
JP1.
We have a telemeter exit here.
We have outputs for analog servo
I already said that there are motor connections there.
We do Gps connection to there.
Here, an important thing about the card,
on the old cards I2c was there
but on the 2.8 modules,
it is moved to below the Gps.
We make this choice by using this jumper.
When this jumper is on the first switch,
it'll use compass which is in the card.
If you want to use an external compass by attaching there,
let me show you jumper, it's a little part which makes a short-circuit.
We withdraw jumper from its place,to use external compass.
On this side of the card, we have an Usb input which we'll use it to load firmware.
That's all about the card.
We can pass to installation.
Yes, next step is the installation
First, we'll load the firmware.
For that we connect it to computer.
Yes, lights are on, card is activated.
Computer recognized it.
We go to mission planner interface
and initial setup.
But we don't click connect button now
because if we click it, card's software starts working so we can't load firmware.
From initial setup to install firmware,
here, updated firmware is downloaded.
After, we choose APM copter,
as we gather a copter.
We say yes.
After that shows an error.
I've already explained that there won't be any update for apm cards. (Last firmware is 3.2.1)
We click to ok to load the last firmware that the card supports.
First, the version is downloaded
and loaded to card.
Firmware is verified.
We successfully loaded last version of the card.
Now, we can connect to card by clicking connect button.
Yes, after connecting to card's interface,
firstly, we'll do basic settings.
For that, we select mandatory hardware
and then frame type.
On the drone that we'll use, there is no motor on the apm's front.
It's the different from plus.
As you see, on the version X motors are on the front right and left corners and rear corners.
There isn't any motors on the rear and front
so correct type of frame is already choosed.
After that we go to accel calibration,
here we'll do calibration of gyroscope.
For that, we have to be sure that surface where we'll do that should be flatwise.
For this reason, we've checked this surface with water gage to be sure.
As you see, there is an arrow that shows the front side.
We will tilt the card to the right and left.
We should specify these directions as arrow's direction is front side.
Now, we can start.
First, let's start calibration.
We hold in a stand position and click 'click when done'.
After, we'll tilt card to left and click again.
And right.
we hold card as arrow looks below
and the reverse.
Finally, on its back.
Calibration is successfully done.
After this operation, if we go back to page flight data,
we can see that gyroscope started working.
That's all for this video.
Thanks for watching.
I wish you all unbroken flights
