树莓派新发布了Zero 2 W
10月29日,树莓派官方发布了一款比巴掌还小的微型电脑Zero 2 W,售价仅为15美元(约合人民币95元)。需要注意的是,这款微型电脑和我们平时常见的PC有着很大的差距。

在其官方新闻中,树莓派创始人 Eben Upton 表示,Zero 2 W 采用和树莓派 3 相同的四核心 64bit 博通 BCM2710A1 SoC,但 ARM 核心主频降至 1GHz,辅以一颗 512MB 的 LPDDR2 SDRAM 内存颗粒并和 SoC 封装在了一起。

在接口方面,Zero 2 W 拥有一个 USB 2.0 接口(支持 OTG 功能)、一个与 HAT 兼容的 40 pin I/O 接口、一个 MicroSD 卡槽、一个 Mini HDMI 视频输出接口、一个复合视频 / 重置针脚焊点以及一个 CSI-2 摄像头连接器。
在通讯交互方面,Zero 2 W 支持 2.4GHz 频段的 802.11 b/g/n Wi-Fi 以及蓝牙 4.2(低功率)。该板支持 H.264、MPEG-4(1080p 30 帧)、H.264 的音视频编码(1080p 30 帧)以及 OpenGL ES 1.1/ 2.0。

树莓派的单片机产品虽然不是我们生活中常见的PC设备,但它在智能仪表、实时工控、导航系统、家用电器等领域都有广泛应用,好处就是体积小、功耗低、构造简单、运算力够用且功能完善。
此外,树莓派的Zero系列产品由于体积价格便宜,成为学习以及从事Linux相关工作的用户的不二之选。同时,该产品也很适合想要了解计算机工作原理以及结构的消费者。

树莓派Zero 2 W理论上可以运行各种树莓派兼容的系统,不过有网友表示,运行树莓派OS会更加稳定。Zero 2 W也能够适配目前所有的配件,Eben Upton表示,这款单片机很快就会在英国、欧盟、美国、加拿大等地区开售。
当然,觉得这种产品还是看看就好,不太适合普通消费者,对于长期“折腾”Linux系统的用户来说倒是挺好的。如果是想买来刷Windows11系统的用户,建议还是放弃吧,这个性能决对让你崩溃!
