Hello everyone,
I'm Wukong, and today's video is
a sharing video of the Raspberry Pi
peripheral series kit.
In the past,
I actually shared an expansion kit for the
Raspberry Pi 4. Its brand is called DeskPi.
Careful friends
will know that today
we also share DeskPi. Another product is DeskPiLite,
which I shared
before is a
version of their PRO.
At that time, many people asked me
where I bought the expansion kit,
and I was very helpless to say that
I could only buy it through the way of
overseas shopping in the United States and Asia,
which made many small partners flinch,
because as we all know, not everyone has the conditions for overseas shopping.
And Haitao still has certain
risks at present,
so I am very happy to tell you
about this video today.
At present, the DeskPi brand has been sold in China,
and the product we are talking
about today is already available on Jingdong.
It has been put on the shelves.
First of all, this video today is not a video with goods.
So you can't find any purchase
links below the video.
I am here to give a unified answer
If you are a foreign user
you can go directly to Meiya to buy it
If you are a domestic user
you can go directly to Jingdong to search it by yourself
Do not ask me what to buy links
I believe you have the ability to retrieve
The first thing many people think about when
they buy a Raspberry Pi is the cooling of its CPU.
As we all know
the CPU heat of Raspberry Pi is still a little high
sometimes it can reach 55 degrees in summer
so if the temperature is too high
it can only reduce the frequency
which will affect the performance of the whole Raspberry Pi
Second
how to consider its shell and what kind of shell should be bought
Third, does it have certain expansibility,
so today I will open the box for you with some questions.
Today's one is from DeskPi DeskPi Lite
Well
what we unpacked today is an expansion kit for the Raspberry Pi 4
called DeskPi Lite
An advanced version of it has been
introduced in the previous video.
I don't know if you have any impression.
This DeskPiPRO has a metal shell and
is relatively large in size,
while the one
we unpacked today is relatively
small in size and size.
This is a Raspberry Pi size
and this is a regular shell
This is its manual.
Through this manual
we can see that it is more expanded
The original HDMI interface is mini
but after this expansion
it becomes a standard size HDMI interface
and at the same time
it retains the typec power supply mode
When we open the manual,
we can see that this time its shell
is still equipped with an active cooling fan.
There is no doubt that it is its noumenon.
There is a DeskPi on it,
and there are two more
USB 2.0 interfaces on this side.
This is an extended USB 2.0,
not the Raspberry Pi itself. On the front,
you can see the
two full-size standard HDMI interfaces
we just mentioned.
You can see that the gap here is where
the Raspberry Pi is installed.
We can put the Raspberry Pi development
board in it later.
The back is where the radiator grille is
and you can see that there are hooks on both sides
which means you can hang it on the wall
Then these four sides are all foot pads
Let's take it apart and have a look
All right, this way, I'll soon get the screws off.
Ok, let's see what's inside.
First of all, this bag is a screw and a thermal pad.
This is where its main circuit board is.
After it is removed,
it is its expansion board.
The full-size HDMI interface we saw before is in this place.
Then this is the place for audio output
which is also extended through the interface
and two USB 2.0 interfaces are extended
Look at the rest of the place
What is this
Ok
there is no doubt that this is the cooling fan for the CPU
and there are some metal heat sinks on it
This is the shell of my original Raspberry Pi
It can be said that the shell has no other function
It is just a shell
Okay, now I've taped all the
exposed chips on the
Raspberry Pie. Conductive heat
but before installing the CPU cooling fan
it is best to connect the expansion version to it first
which is absolutely a rule of thumb
On the left is the extended version
and on the right is the Raspberry Pi body
It has a 3.5mm audio here
I think this place is particularly easy to break
so you must pay special attention before inserting it
Okay, so that's it.
The installation method of this fan is very simple
just connect it directly to the GPIO interface
Ok, that's it.
Well, the following is very simple.
It's OK to put it directly into the shell.
After installation
you can see that the interfaces of the original Raspberry Pi are not affected
Then you can see that there
are two USB 2.0 extensions on
the front of it,
and at the same time, this place is also the location of the TF card slot.
There is a small detail here,
that is, the position of the indicator light is also reserved,
and then here is the power switch,
in fact, I think it is necessary to add a
switch to the Raspberry Pi.
Okay, let's electrify it now to see its actual effect.
Now I've actually been powered on for more than an hour
and this time
in order to facilitate the demonstration
I brushed into a system that everyone is familiar with
which is the openwrt system of soft routing
This time
let's see if its heat dissipation performance can be used as a soft router
We all know that the heat of Raspberry Pi is relatively high
usually its temperature is above 55 degrees
so if there is no heat dissipation
it is absolutely impossible
After adding heat dissipation this time
let's take a look at its overall performance
Well
at this time
we can take a look at the overview of OpenWrt
It is clearly written here that its temperature is between 41 and 42 degrees
and it is a state of wandering back and forth
I think this temperature is already quite low,
somewhat catching up with the heat level of
this x86's soft routing similar to the j1900.
In fact, it is not
easy for arm routers
or soft routers to reach this level,
because we all
know that the temperature is very high if there is no
heat dissipation at ordinary times.
Of course, if you are still
not satisfied with the temperature,
you can use the USB fan to
further reduce it.
Let us see to what extent.
If you add a fan
the temperature will drop further
even to 35 degrees
I think it's a little too much
a little too much
Is 35 degrees too low?
I think the general semiconductor does not seem to be so delicate
so in fact
for soft routing
I think the best temperature is within 45 degrees
which is basically acceptable
If your soft routing CPU is already above 50 degrees
it's a little risky at this time
Of course, there is no big risk,
just that its performance may be further reduced.
When we use the cooling fan,
including the whole shell, it will never reach 50 degrees.
According to my actual measurement
its highest temperature is 4647 degrees
and it is in the case of high load operation
For example, if we watch a YouTube or Netflix movie,
we may need KX to surf the Internet at this time.
At this time, the encryption and decryption algorithm of the CPU will be called.
Maybe the temperature will rise,
but it will not be too high. At most,
it will be 45 to 46 degrees.
So it's basically completely competent.
Personally, I don't think it's
necessary to add another
fan with the shell.
It's
been one night now,
about 17 hours.
Then we look at the surface
it is still very cool
whether it is the front or the side
including its bottom
we can use the temperature gun to measure that it is still at room temperature
more than 30 degrees
that is
it can hardly feel too much temperature
Let's take a look at the core temperature of the CPU.
You can
see that the screen shows that the core temperature
of the CPU is still around 45 degrees,
which is a level below 45 degrees,
so the cooling fan plays a big role.
Since it is an expansion kit,
the full-size HDMI must be tested,
so here I connected two HDMI
interfaces and two monitors.
Of course
there is a 4K monitor and a 1080p monitor
In theory, the Raspberry Pi
system supports dual 4K monitors.
You can see that both
monitors have successfully lit
up its full-size HDMI
without any problem.
Of course, not all systems
support two-way HDMI interfaces.
For example, if you brush into a player's system OMSC,
it must be a display,
which is directly related to the system.
Ok, the above is my personal experience,
a brief summary
of this Raspberry Pi DeskPiLite expansion kit,
I think it is
quite qualified users are
just concerned about a few issues.
The first is the problem of heat dissipation
The package of the shell has a radiator
which can basically be controlled within 45 degrees
I did the test at a room
temperature of about 27 degrees.
Whether you brush the openwrt routing
system or the Raspberry Pi's own Raspberry Pi system,
it is basically maintained within 45 degrees.
This temperature can run stably.
Of course, if you still want the ultimate pursuit,
you can even install USB fans,
depending on personal preferences.
The second is the full-size HDMI port
which is quite useful
For the vast majority of users,
the monitor or
TV is full-size HDMI,
so it's impossible to have a mini model,
so we avoid the adapter.
Third, I think the design of the shell is quite pleasant,
the overall appearance of the volume is still very small,
but its heat dissipation is really no problem.
Although it is a plastic body,
it gives people the
feeling that it
has changed from a development board
to a mature commercial product.
Anyway, I like it very much.
Then again
the video we are talking about this time is mainly about third-party accessories
not about Raspberry Pi
because the price of Raspberry Pi is soaring now
so it is not suitable to start at present
So today this video is still for those
users who have already bought the Raspberry Pi.
You can use it as an alternative. Personally,
I think it is a very
qualified third-party expansion kit.
Finally, let's talk about its front USB interface.
I found that its front USB interface does not
seem to be correctly recognized by
the OTG mouse under the Raspberry Pi system.
It may be due to some reasons of the driver,
but the front USB does have power supply.
