Friday was a big day for Nintendo, and indeed the gaming community as a whole, with the launch of the new and innovative console-tablet hybrid, the Nintendo Switch. For consumers lucky enough to get their hands on this new release over the weekend, tearing it apart is probably the very last thing on their minds. Here at TechInsights, however, we couldn’t wait to get started and take a look at what is bringing our heroes, Mario and Link, to life once again.
This unique combination of mobile play with big screen living room comfort in one integrated system gives us at least four different component parts to tear down and do what we do best. We were particularly eager to delve into the那些Joy-Con控制器的神秘面纱看看我们能不能提供一些新的见解。一定要通读到底,看看我们发现了什么。
任天堂交换机主控制台
我们将从主控制台单元开始我们的冒险。与Joy-Con控制器连接在两侧的插槽中,此单元构成交换机的移动游戏系统组件。它包括一个触摸屏以及混合动力系统的主要PCB和部件。
在这个主要的PCB上,我们发现了预期的NVIDIA ODNX02-A2 TEGRA SOC以及一个Broadcom BCM4356单芯片5G Wi-Fi IEEE 802.11ac 2×2 MAC /基带/无线电,带有集成的蓝牙4.1,FM接收器和无线充电,aSTMicroelectronics SH6416轴加速度计和陀螺超低功率MEMS惯性传感器,aSamsung K4F6E304HB-MGCH16 Gb LPDDR4 SDRAM和德州仪器BQ24193battery charger.
更新!
在对任天堂交换机的GPU进行后续处理之后,我们确定处理器是Nvidia Tegra T210。T210CPU具有4个Cortex A57和4个Cortex A53处理器内核,GPU是GM20B Maxell内核。在此下载高分辨率映像.
在一个单独的存储板上是一个三星KLMBG2JENB 32 GB EMMC.有趣的是,IFIXIT在这里发现了一个东芝Thgbmhg8c2lbail 32 GB emmc NAND闪存IC。这个独立的存储板是否表明了未来模型更新的计划与扩展存储,因为有些人推测,或者只是为了适应内存制造商的这些变化?
PCB的背面包括Maxim MAX77621 DC/DC转换器、Realtek ALC5639音频编解码器和Pericom PI3USB30532 USB 3.0/DP1.2 3:2矩阵开关。
Also on a separate display board, we found the STMicroelectronics FT9CJ touchscreen controller. The FT9CJ is from the STM FingerTip multi-touch ultra-low power touchscreen controller product line. Based upon observations of the pinout and the flex connector, this touch solution may have up to 60 channels. This device is not on the STMicroelectronics website and must clearly be a unique design by STM for Nintendo. STMicroelectronics has had great success with their touchscreen solutions in the mobile phone industry. In fact, they are branching out even further into automotive and industrial as described in this最近的一篇文章.
扩展底座
当主移动单元放入扩展坞时,将变量进入其起居室控制台对应物,并将您的游戏带到大屏幕上的生活。这种额外的功能由a带给您通过实验室VL210-Q4USB3.0集线器控制器,一个STMicroelectronics 32P048(可能是MCU),一个Macronix MX25V2006E2 MB串行闪光灯和一个MX25L512E512 Kb serial Flash, aMEGACHIPS STDP2550Mobility DisplayPort(MyDP)到HDMI转换器,a德州仪器TLV62130ARGT(“Vuni”包标记)DC / DC转换器和未知的M92T55芯片。
The surprising story of the early days of the Nintendo Switch is the Joy-Con controllers. Before we dig into the connectivity issues and their possible causes, let’s begin with what we know.
This device is the STMicroelectronics LD39020D low dropout regulator (LDO) that which features a very high power supply rejection ratio (PSRR) and a low quiescent current of 200 mA. This LDO is used in each controller and the docking station.
虽然在功能和性能上有所不同,但左右控制器有几个共同的部分。其中包括Macronix MX25U4033E4 Mb serial CMOS XSMIO® (Serial Multi I/O) Flash memory, a德州仪器BQ24072(“CKP”包装标记)电池充电器,a博通BCM20734Bluetooth transceiver, and a STMicroelectronics SH627 6-axis accelerometer and gyroscope ultra-low power MEMS inertial sensor, part of the LSM6DS3 family, a system-in-package featuring a 3D digital accelerometer and a 3D gyroscope. The Broadcom BCM20734 is of particular interest as it supplies the connectivity between the controllers and the main console, but more on that later. In the meantime, have a look at the BCM207xx top metal die photograph.
此外,正确的JOY-CON包括STMicroelectronics NFCBEA B123D6 NFC IC,其为AMIIBO数据提供了可用于将字符插入各种游戏的界面。
Joy-Con红外相机Module
Also residing in the right Joy-Con is another feature, the motion IR camera. This camera is an infrared CMOS image sensor that is used to detect object shape and distance and,according to Ars Technica and Nintendo,will be able to record full video in the future. This camera sensor appears likely to be manufactured by OmniVision, and has a die size of 3.90 mm x 3.73 mm and a pixel pitch of 5 µm.

Joy-con连接的神秘面纱
自任天堂交换机的初始审阅者版本以来,在手持模式和主控制台中,Joy-Con控制器之间存在广泛的间歇连接挑战。在线视频show the player covering the controller with their other hand, or placing it behind their back, causing the controller signal to jump and sometimes disappear altogether. These problems were first noticed in reviewer units causing concern among consumers. While the issue is not consistently replicated in all units (or even with both controllers), they persist in newer consoles, even after installing a software update reported to solve the problem.
In this screen capture from the video linked above the player has moved his right hand to cover up the “inside” of the Joy-Con. On that inside surface, just under the plastic cover, is the antenna for the BCM20734 Bluetooth 4.1 SoC.
这个同步问题仅仅是因为覆盖了天线,还是这里发生了更多的事情?
On Nintendo’s support site they suggest interference from other BT transmitters may interfere with the Joy-Con signals, stating that “in most cases it will be enough to move these devices three to four feet away from the Nintendo Switch console and/or Joy-Con controllers. However, if you continue to experience this issue, please power these devices off while using the Nintendo Switch console.” Not only are reports of its efficacy mixed, this is really an impractical solution. How many game systems are in a room where there are other BT devices functioning? These days, probably all of them.
不幸的是,我们太渴望开始我们的拆除来首先测试我们的单位,因此我们不确定我们是否有一个好的,但是有可能在那里有一个糟糕的设计。在我们的右图中,如下图所示,我们看到一个非常裸露的骨头BT天线设计:连接器,电线和非常小的天线。也许天线太小了。
Here in a cleaner image, the antenna connection of the right controller can be seen more clearly. The gold connector on the left leads to a rectangular piece of fiberglass, or FR4, with a metallic coating that is the actual antenna. This rectangular plate resides on the flat edge of the Joy-Con and is underneath that flat face plate.
According torecent reports,左控制器不共享此设计,而是“左Joy Con中的天线直接焊接到主板上,紧挨着一个金属盒。”在下面的并排图像中,可以看到左控制器中的此位置确实没有天线。这就为左控制器更常见的问题提供了可能的解释。
任天堂对这些报道反应迟钝。他们的答案,当我们得到一个,将告诉我们。他们会发布另一个更可靠的软件更新吗?或者,消费者的“故障”单位提供更换或维修,指向设计缺陷?我们一定会关注他们下一步的行动。
