Raspberry Pi Zero 2 W is Here!
|
||||
======
|
||||
|
||||
Raspberry Pi Zero W is one of the most affordable single-board computers that include wireless and Bluetooth connectivity.
|
||||
|
||||
While there are some differences between the [Raspberry Pi Zero vs. Raspberry Pi Zero W][1], both were pretty solid deals considering they launched for $5 and $10, respectively.
|
||||
|
||||
Now, Raspberry Pi has unveiled the successor to this lineup after about six years, i.e., Raspberry Pi Zero 2 W priced at **$15**.
|
||||
|
||||
Even with [Raspberry Pi increasing its price][2], I’d say $15 for a new-gen board for improved multi-threaded performance should be a good buy.
|
||||
|
||||
Let us take a look at what it has to offer and what’s new.
|
||||
|
||||
### Raspberry Pi Zero 2 W: Specifications
|
||||
|
||||
![][3]
|
||||
|
||||
Raspberry Pi Zero 2 W is powered by the same chip used in the launch version of Raspberry Pi 3.
|
||||
|
||||
With the frequency slightly clocked down to 1 GHz, it still manages to promise up to 5x times the performance of the original Raspberry Pi Zero.
|
||||
|
||||
Here’s what it comes packed with:
|
||||
|
||||
* Broadcom BCM2710A1, quad-core 64-bit SoC (Arm Cortex-A53 @ 1GHz)
|
||||
* 512MB LPDDR2 SDRAM
|
||||
* 2.4GHz IEEE 802.11b/g/n wireless LAN, Bluetooth 4.2, BLE
|
||||
* 1 × USB 2.0 interface with OTG
|
||||
* HAT-compatible 40 pin I/O header footprint
|
||||
* MicroSD card slot
|
||||
* Mini HDMI port
|
||||
* Composite video and reset pin solder points
|
||||
* CSI-2 camera connector
|
||||
* H.264, MPEG-4 decode (1080p30); H.264 encode (1080p30)
|
||||
* OpenGL ES 1.1, 2.0 graphics
|
||||
|
||||
|
||||
|
||||
Looking at the specifications, it is impressive enough when you consider the zero form factor it comes with. Not to forget, they have added more copper layers to manage the heat generated from the upgraded processor.
|
||||
|
||||
![][4]
|
||||
|
||||
Furthermore, the wireless circuitry is sealed with a metal shield can that should make it easy for use in a commercial end-product.
|
||||
|
||||
![][5]
|
||||
|
||||
If you already have a case for Raspberry Pi Zero, it should most likely work with Zero 2 W.
|
||||
|
||||
As per the [official announcement][6], Raspberry Pi mentions:
|
||||
|
||||
> The exact performance uplift over Zero varies across workloads, but for multi-threaded [sysbench][7] it is almost exactly five times faster.
|
||||
|
||||
The tiny form factor and the performance uplift should make it an ideal board for security cameras and many other IoT projects. You may take a look at our list of [DIY projects for Raspberry Pi Zero W][8] for ideas.
|
||||
|
||||
### A New USB Power Supply
|
||||
|
||||
![][9]
|
||||
|
||||
Along with a new board, Raspberry Pi also introduced an improved USB power supply with a peak current rating of 2.5A.
|
||||
|
||||
The power supply comes with a micro-USB connector instead of USB-C. Even though this isn’t meant for the new Zero 2 W, it is geared for Raspberry Pi 3B or 3B+.
|
||||
|
||||
### Availability & Pricing
|
||||
|
||||
![][10]
|
||||
|
||||
The Raspberry Pi foundation has clarified that they won’t discontinue Raspberry Pi Zero and Zero W until January 2026.
|
||||
|
||||
So, if you want to save money for an experiment, you can proceed with the older boards.
|
||||
|
||||
The new Zero 2 W will be available at $15 from official resellers. The availability is limited to the UK, EU, United States, Canada, and Hong Kong.
|
||||
|
||||
It should be available for Australia and New Zealand in November, and more countries will be added in the next few months.

树莓派 Zero 2 W 来了！
|
||||
======
|
||||
|
||||
> 树莓派 Zero W 的继任者来了！仅售 15 美元，它包括一些承诺的升级和改进。
|
||||
|
||||
|
||||
|
||||
树莓派 Zero W 是最实惠的包括了无线和蓝牙连接的单板计算机之一。
|
||||
|
||||
虽然 [树莓派 Zero 与树莓派 Zero W][1] 之间有一些区别，但考虑到它们分别以 5 美元和 10 美元的价格推出，两者都是靠谱的选择。
|
||||
|
||||
现在，树莓派在大约 6 年后推出了这个系列的继任者，即树莓派 Zero 2 W，售价为 **$15**。
|
||||
|
||||
即使 [树莓派提高了价格][2]，我想说 15 美元买一块改进了多线程性能的新一代电路板应该是个不错的选择。
|
||||
|
||||
让我们来看看它有什么优点和新的东西。
|
||||
|
||||
### 树莓派 Zero 2 W 的规格
|
||||
|
||||
![][3]
|
||||
|
||||
树莓派 Zero 2 W 使用了在树莓派 3 发布版中使用的相同芯片。
|
||||
|
||||
虽然频率略微降低到了 1GHz，它仍然能够保证其性能是原来树莓派 Zero 的 5 倍。
|
||||
|
||||
下面是它的规格：
|
||||
|
||||
* 博通 BCM2710A1，四核 64 位SoC（Arm Cortex-A53 @ 1GHz）
|
||||
* 512MB LPDDR2 SDRAM
|
||||
* 2.4GHz IEEE 802.11b/g/n 无线网络、蓝牙 4.2，BLE
|
||||
* 1×USB 2.0 接口，带 OTG
|
||||
* 与 HAT 兼容的 40 针 I/O 针脚
|
||||
* MicroSD 卡插槽
|
||||
* mini HDMI 接口
|
||||
* 复合的视频和复位引脚焊点
|
||||
* CSI-2 相机连接器
|
||||
* H.264，MPEG-4 解码（1080p30），H.264 编码（1080p30）
|
||||
* OpenGL ES 1.1，2.0 图形
|
||||
|
||||
看看这些规格，考虑到它的外形尺寸，它足够令人印象深刻。不要忘了，他们增加了更多的铜覆层来处理升级后的处理器产生的热量。
|
||||
|
||||
![][4]
|
||||
|
||||
此外，无线电路是用金属屏蔽密封的，这应该使它容易用于商业终端产品。
|
||||
|
||||
![video][5]
|
||||
|
||||
如果你已经有了树莓派 Zero 的外壳，那么它应该很有可能适用于 Zero 2 W。
|
||||
|
||||
根据 [官方公告][6]，树莓派提到：
|
||||
|
||||
> 与 Zero 相比，确切的性能提升因工作负载而异，但对于多线程的 [sysbench][7] 来说，它几乎正好是五倍的速度。
|
||||
|
||||
小巧的外形和性能的提升应该使它成为安全摄像机和许多其他物联网项目的理想板卡。你可以了解一下我们的 [树莓派 Zero W 的 DIY 项目][8] 清单，看看有什么灵感。
|
||||
|
||||
### 一个新的 USB 电源
|
||||
|
||||
![][9]
|
||||
|
||||
除了新的电路板，树莓派还推出了一个改进的 USB 电源，峰值电流为 2.5A。
|
||||
|
||||
该电源配备了一个 micro USB 接口，而不是 USB-C。尽管这不是为新的 Zero 2 W 准备的，而是为树莓派 3B 或 3B+ 准备的。
|
||||
|
||||
### 可用性 & 价格
|
||||
|
||||
![][10]
|
||||
|
||||
树莓派基金会已经澄清，他们在 2026 年 1 月之前不会停产树莓派 Zero 和 Zero W。
|
||||
|
||||
因此，如果你想省钱做实验，你可以继续使用旧板。
|
||||
|
||||
新的 Zero 2 W 将在官方经销商处以 15 美元的价格出售。目前供货范围仅限于英国、欧盟、美国、加拿大和香港。
|
||||
|
||||
它应该在 11 月在澳大利亚和新西兰上市，在接下来的几个月里会有更多国家加入。
