Nintendo issued the latest 3DS XL handheld, where is the "new"? The following dismantles a pleasant understanding from the inside.
We first compare new and old 3DS XL appearance changes. The new 3DS XL weight is 329g, which is less than 7G, and the size is not large. It is 160 * 93.5 * 21.5mm, respectively, the latter is 156 x 93 x 22 mm.
Left is the new 3DS XL, right as old, two buttons in the top of the new model, and the interface position has also been adjusted.
The new 3DS XL fuselage back shell is more bright
The new 3DS XL is compared with the old stylus, the appearance is slightly different, the weight is the same, the plastic material is cheap.
There are more than zl, Zr two buttons on the top of the body, and the interface part has also been adjusted. The new model of the body is more shining. The storage position of the stylus is changed from the side of the fuselage to the top of the body. Take the stylus and can be easily dismantled. The new 3DS XL and the previous generation of the touch pen appearance have some slight differences, all of which are plastic materials, which look cheap.
Use the cross screwdriver to unload the upper two screws above the back
First, dismantling needs to start from the back shell from the body. The two screws of the fixed rear shell were removed using a cross screwdriver. It is worth mentioning that the Micro SD card slot of the machine is designed inside the rear housing, so you want to change the SD card.
Remove the back shell cover close-up
The new battery uses 3.7V 1750mAh 6.5WH, which can be used with old
Remove the rear shell, not only you can see the Micro SD card slot, but also the battery slot. The new 3DS XL battery uses replaceable design, located on the left side of the fuselage, and the old model is designed to the right. The new battery uses 3.7V 1750mAh 6.5WH specification to be universal with the old body.
Next, remove the Micro SD card, just push it forward, it will pop up, the machine supports 32GB SD card for users to expand, but it is understood that only 4GB of official standard is, for the favorite one Players playing games, the problem is not big.
Two screws on the back shell are hidden by rubber plug
Removing the remaining six screws of the back shell can be separated, but pay attention to the disconnection button
The button cable on the back shell is connected to the motherboard. Be careful not to pull it. Through the smaller rubber plug hidden the two body screws, after removing them, just remove it again, then remove it down on the rest of the back shell. But pay attention to the button integration on the back housing, so you also need to separate the button cable to the motherboard. After removing, the construction of the new 3DS XL body inside is unbed. What improvements have new inside? Let's discover it! (Next)

Silk powder remaining at the back shell
First let's take a look at the interior of the back shell separated in the last link. Nintendo does not seem to pay much about the design aesthetics inside the body, and the slit of the back shell is even still overflowing the powder. Although the black engineering plastic material is easy to open, but the feel cannot be comparable to the metal, and the manufacturer is really strict.
Separate motherboard cable
Next, in order to separate the motherboard, we need to separate each of the connecting motherboards, including the button, two screens, rockers, cameras, etc., they will "bundle" from each position of the motherboard. Live, but we only need to gently you can separate them.
Separate rocker controller
Removing the motherboard after the motherboard screw can be removed
After separating the cable, the motherboard is still soft, we found that the rocker assembly is fixed by the screw and the motherboard, so we will fix it four screws, and remove the screws of the fixed motherboard together, carefully observe these screws It seems to have two different sizes. At this time, the motherboard finally was freed, and the lighting of our hand flew out the binding and the chains of the cable.
In addition to the motherboard, other parts of the fuselage also have two PCBs, but we don't care about them, look at what is new on the motherboard.
Connect the Micro SD card slot on the motherboard, and the previous generation is an SD card slot
On the motherboard, we found the Micro SD card slot, up to 32GB capacity, bringing users to make you more than 10 hours without repeating the level of Super Mary brothers, without worrying about memory is not enough. The previous generation uses an SD card slot, and the capacity supported is small.
When I arrived at the motherboard, it is time to come to something boring, let's take a look at what the chips selected for the motherboard for the motherboard.
Be
Red chip: Nintendo 1446 17CPU, can be seen from the name of the ARM architecture, and from functional I speculate should also belong to the Cortex A9 architecture chip, which may adopt multi-core to improve performance.
Green chip: Fujitsu 82MK9A9A 7LFCRAM 1445 962 FCRAM memory chip
Orange chip: Atheros AR6014G-AL1C Wireless Wi-Fi Module
Yellow chip: Samsung KLM4G1YEMD-B031 4GB EMMC NAND flash memory
Light Blue Chip: Deyi 93045A4 49AF3NW G2 (probably a power management chip)
Dark Blue Chip: Renesas Electronics UC KTR 442km13 TK14
After reading the front, let's take a look at what the chip on the back of the motherboard is:
Be
Red chip: Deyi AIC3010D 48C01JW (speculation is an audio decoding chip)
Orange chip: NXP S750 1603 TSD438C RF chip
Yellow chip: German PH416A output development

(Next)
Let's go back to the inside of the fuselage, and two PCBs have not been removed. Now our goal is it.
Game card reader integrated on a PCB
One of the PCBs integrated game card readers, this card reader believes that a certain day will be eliminated by flash chip, but this way of reading the game also makes us think of a child when it is a mistake. Experience.
Remove the game button
Let's take a look at another PCB. It turns out that it is a game button control board. The front design has a micro-motion of the ABXY button. The C-Stick lever is also connected to this. When it comes to it, the author can't help but think of the ThinkPad series Classic small red dots, the operation method is the same.

Pour out button agencies
Pumping the machine, gently pick it up, but the button on the body will drop it.
Remove the frame
NFC antenna close-up
The frame behind the screen uses a buckle with the fuselage, peeling the frame, and the back is also hidden with the NFC antenna to connect to the Amiibo small doll launched by heaven. These small dolls are the roles in Nintendo game. When we buy these small dolls and interact with the machine through NFC, the corresponding role in the game activates specific functions.
Bottom screen is separated from the body
The bottom screen is pasted on the fuselage, because there is no frame support, unloading is very easy. We gently pushed from the outside, and the screen opened. It seems that the screen is very thick, and the screen of the mobile phone that uses OGS technology is not in the same day. I believe that if the industrial design is more refined, it can be done thinner. (Next)
In the previous session, we removed the internal components of the lower part of the fuselage, see three PCB boards and the above chips and button, but compared to the following, the author is also more touching 3D screen and 3D camera more Interests.
Four screws are also hidden on top of the fuselage
Separation machine top panel
Unload the screw of the bottom hinge of the panel to separate the front panel of the front panel
On the top of the fuselage, there is also a rubber plug hidden four screws, and then remove them, you can knock on the slit of the screen border by leather stick, and expand it little, until you open the front panel of the top body. However, if you want to separate the front panel, you also need to remove the fixed screw of the panel bottom beading with a screwdriver.
Remove the camera array
Close up of the back of the camera array, two cameras can shoot 3D screen
Front camera close-up
The new 3DS XL camera module is the most special, Nintendo integrates the front camera and the rear double camera in an array. The front camera can track the position of the human eyes in addition to the photo, and the screen can bring excellent 3D effect to the user in each angle, is there any advanced? There is also a feature that all the cables are intended to avoid the naked eye 3D screen, perhaps to reduce the impact of signal interference on screen display.
Naked eye 3D screen closeup
Dismantle the whole family
After removing the screen, this dismantling will tell a section. Don't look at it, but the process of separation is very difficult because the two cables of the screen are connected to the motherboard through the fuselage hinge, so the cable is taken out from the hinges is a difficult process, but in the end we Success, the screen is free! This dismantling is also close to the end. Finally, give you a family blessing.
