Unboxing the Raspberry Pi 4
|
||||
======
|
||||
The Raspberry Pi 4 delivers impressive performance gains over its
|
||||
predecessors, and the Starter Kit makes it easy to get it up and running
|
||||
quickly.
|
||||
![Raspberry Pi 4 board, posterized filter][1]
|
||||
|
||||
When the Raspberry Pi 4 was [announced at the end of June][2], I wasted no time. I ordered two Raspberry Pi 4 Starter Kits the same day from [CanaKit][3]. The 1GB RAM version was available right away, but the 4GB version wouldn't ship until July 19th. Since I wanted to try both, I ordered them to be shipped together.
|
||||
|
||||
![CanaKit's Raspberry Pi 4 Starter Kit and official accessories][4]
|
||||
|
||||
Here's what I found when I unboxed my Raspberry Pi 4.
|
||||
|
||||
### Power supply
|
||||
|
||||
The Raspberry Pi 4 uses a USB-C connector for its power supply. Even though USB-C cables are very common now, your Pi 4 [may not like your USB-C cable][5] (at least with these first editions of the Raspberry Pi 4). So, unless you know exactly what you are doing, I recommend ordering the Starter Kit, which comes with an official Raspberry Pi charger. In case you would rather try whatever you have on hand, the device's input reads 100-240V ~ 50/60Hz 0.5A, and the output says 5.1V --- 3.0A.
|
||||
|
||||
![Raspberry Pi USB-C charger][6]
|
||||
|
||||
### Keyboard and mouse
|
||||
|
||||
The official keyboard and mouse are [sold separately][7] from the Starter Kit, and at $25 total, they aren't really cheap, given you're paying only $35 to $55 for a proper computer. But the Raspberry Pi logo is printed on this keyboard (instead of the Windows logo), and there is something compelling about having an appropriate appearance. The keyboard is also a USB hub, so it allows you to plug in even more devices. I plugged in my [YubiKey][8] security key, and it works very nicely. I would classify the keyboard and mouse as a "nice to have" versus a "must-have." Your regular keyboard and mouse should work fine.
|
||||
|
||||
![Official Raspberry Pi keyboard \(with YubiKey plugged in\) and mouse.][9]
|
||||
|
||||
![Raspberry Pi logo on the keyboard][10]
|
||||
|
||||
### Micro-HDMI cable
|
||||
|
||||
Something that may have caught some folks by surprise is that, unlike the Raspberry Pi Zero that comes with a Mini-HDMI port, the Raspberry Pi 4 comes with a Micro-HDMI. They are not the same thing! So, even though you may have a suitable USB-C cable/power adaptor, mouse, and keyboard on hand, there is a pretty good chance you will need a Micro-HDMI-to-HDMI cable (or an adapter) to plug your new Raspberry Pi into a display.
|
||||
|
||||
### The case
|
||||
|
||||
Cases for the Raspberry Pi have been around for years and are probably one of the very first "official" peripherals the Raspberry Pi Foundation sold. Some people like them; others don't. I think putting a Pi in a case makes it easier to carry it around and avoid static electricity and bent pins.
|
||||
|
||||
On the other hand, keeping your Pi covered can overheat the board. This CanaKit Starter Kit also comes with heatsink for the processor, which might help, as the newer Pis are already [known for running pretty hot][11].
|
||||
|
||||
![Raspberry Pi 4 case][12]
|
||||
|
||||
### Raspbian and NOOBS
|
||||
|
||||
The other item that comes with the Starter Kit is a microSD card with the correct version of the [NOOBS][13] operating system for the Raspberry Pi 4 pre-installed. (I got version 3.1.1, released June 24, 2019). If you're using a Raspberry Pi for the first time and are not sure where to start, this could save you a lot of time. The microSD card in the Starter Kit is 32GB.
|
||||
|
||||
After you insert the microSD card and connect all the cables, just start up the Pi, boot into NOOBS, pick the Raspbian distribution, and wait while it installs.
|
||||
|
||||
![Raspberry Pi 4 with 4GB of RAM][14]
|
||||
|
||||
I noticed a couple of improvements while installing the latest Raspbian. (Forgive me if they've been around for a while—I haven't done a fresh install on a Pi since the 3 came out.) One is that Raspbian will ask you to set up a password for your account at first boot after installation, and the other is that it will run a software update (assuming you have network connectivity). These are great improvements to help keep your Raspberry Pi a little more secure. I would love to see the option to encrypt the microSD card at installation … maybe someday?
|
||||
|
||||
![Running Raspbian updates at first boot][15]
|
||||
|
||||
![Raspberry Pi 4 setup][16]
|
||||
|
||||
It runs very smoothly!
|
||||
|
||||
### Wrapping up
|
||||
|
||||
Although CanaKit isn't the only authorized Raspberry Pi retailer in the US, I found its Starter Kit to provide great value for the price.
|
||||
|
||||
So far, I am very impressed with the performance gains in the Raspberry Pi 4. I'm planning to try spending an entire workday using it as my only computer, and I'll write a follow-up article soon about how far I can go. Stay tuned!

树莓派 4 开箱记
|
||||
======
|
||||
|
||||
> 树莓派 4 与其前代产品相比具有令人印象深刻的性能提升，而入门套件使其易于快速启动和运行。
|
||||
|
||||
![Raspberry Pi 4 board, posterized filter][1]
|
||||
|
||||
当 树莓派 4 [在 6 月底宣布发布][2]时，我没有迟疑，在宣布的同一天就从 [CanaKit][3] 订购了两个树莓派 4 入门套件。1GB RAM 版本有现货，但 4GB 版本要在 7 月 19 日才能发货。由于我想两个都试试，我两个都订购了让它们一起发货。
|
||||
|
||||
![CanaKit's Raspberry Pi 4 Starter Kit and official accessories][4]
|
||||
|
||||
这是我开箱我的树莓派 4 后看到的。
|
||||
|
||||
### 电源
|
||||
|
||||
树莓派 4 使用 USB-C 连接器供电。虽然 USB-C 电缆现在非常普遍，但你的树莓派 4 [可能不喜欢你的USB-C 线][5]（至少对于树莓派 4 的第一版如此）。因此，除非你确切知道自己在做什么，否则我建议你订购带有官方的树莓派充电器的入门套件。如果你想尝试手头的充电设备，那么设备的输入是100-240V ~ 50/60Hz 0.5A，输出为 5.1V - 3.0A。
|
||||
|
||||
![Raspberry Pi USB-C charger][6]
|
||||
|
||||
### 键盘和鼠标
|
||||
|
||||
官方键盘和鼠标是和入门套件[单独出售][7]，总价 25 美元，并不很便宜，因为你的这台树莓派电脑也只才 35 到 55 美元。但树莓派徽标印在这个键盘上（而不是 Windows 徽标），并且外观相宜。键盘也是 USB 集线器，因此它允许你插入更多设备。我插入了我的 [YubiKey][8] 安全密钥，它运行得非常好。我会把键盘和鼠标分类为“值得拥有”而不是“必须拥有”。你的常规键盘和鼠标应该可以正常工作。
|
||||
|
||||
![Official Raspberry Pi keyboard \(with YubiKey plugged in\) and mouse.][9]
|
||||
|
||||
![Raspberry Pi logo on the keyboard][10]
|
||||
|
||||
### Micro-HDMI 电缆
|
||||
|
||||
可能让一些人惊讶的是，与带有 Mini-HDMI 端口的树莓派 Zero 不同，上面牛皮 4 配备了 Micro-HDMI。它们不是同一个东西！因此，即使你手头有合适的 USB-C 线缆/电源适配器、鼠标和键盘，也很有可能需要使用 Micro-HDMI 转 HDMI 的线缆（或适配器）来将你的新树莓派接到显示器上。
|
||||
|
||||
### 外壳
|
||||
|
||||
树莓派的外壳已经有了多年，这可能是树莓派基金会销售的第一批“官方”外围设备之一。有些人喜欢他们，而有些人不喜欢。我认为将一个树莓派放在一个盒子里可以更容易携带它，可以避免静电和针脚弯曲。
|
||||
|
||||
另一方面，把你的树莓派包装起来会使电路板过热。这款 CanaKit 入门套件还配备了处理器散热器，这可能有所帮助，因为更新的树莓派已经[以运行相当热而闻名][11]了。
|
||||
|
||||
![Raspberry Pi 4 case][12]
|
||||
|
||||
### Raspbian 和 NOOBS
|
||||
|
||||
入门套件附带的另一个东西是 microSD 卡，其中预装了树莓派 4 的 [NOOBS][13] 操作系统的正确版本。（我拿到的是 3.19 版，发布于 2019 年 6 月 24 日）。如果你是第一次使用树莓派并且不确定从哪里开始，这可以为你节省大量时间。入门套件中的 microSD 卡容量为 32GB。
|
||||
|
||||
插入 microSD 卡并连接所有电缆后，只需启动树莓派，引导进入 NOOBS，选择 Raspbian 发行版，然后等待安装。
|
||||
|
||||
![Raspberry Pi 4 with 4GB of RAM][14]
|
||||
|
||||
我注意到在安装最新的 Raspbian 时有一些改进。（如果他们已经存在一段时间了，请原谅我 —— 自从 3 出现以来我没有对树莓派进行过全新安装。）其中一个是 Raspbian 会要求你在安装后的首次启动为你的帐户设置一个密码，另一个是它将运行软件更新（假设你有网络连接）。这些都是很大的改进，有助于保持你的树莓派更安全。我很希望能有一天在安装时看到加密 microSD 卡的选项。
|
||||
|
||||
![Running Raspbian updates at first boot][15]
|
||||
|
||||
![Raspberry Pi 4 setup][16]
|
||||
|
||||
运行非常顺畅！
|
||||
|
||||
### 结语
|
||||
|
||||
虽然 CanaKit 不是美国唯一授权的树莓派零售商，但我发现它的入门套件的价格物超所值。
|
||||
|
||||
到目前为止，我对树莓派 4 的性能提升印象深刻。我打算尝试用一整个工作日将它作为我唯一的计算机，我很快就会写一篇关于我探索了多远的后续文章。敬请关注！
