BCM2326的芯片了, 4核 1G内存 看着还不错,另外还可以免费用windows10
淘宝上配个盒子拿个充电宝,就可以开脑洞了。

刚买了B+,折腾好了NAS,怎么2就出来了……

我的MLDonkey和Syncthing不怎么耗资源,想再跑些啥家庭应用呢?

同没有升级的兴趣。
ARM就算是4核还是ARM,已经打算很久了买x86的小主机来搭家庭云。

比较好奇如何接硬盘的,USB口够用?如果想做那种多盘(例如LVM+RAID)的File Server呢?

现在是拿一台老的笔电(好吧,是MBP 15'' 2011),插了2块SATA硬盘,做了RAID1,因为除了存放文件外,还跑了好多东西在上面。

我觉得门槛低倒是的,论坛里面各种教程都很简单,写的比较完善。
老外的文档做的很敬业,另外外设到位,各种外设价格不贵而且可选择的范围也很大。
国内都是要做的很高端的,自己吧自己的用户群给框死。

文档也要看类型的,同样的bbb的文档也很丰富。但当年看了几百页的am335x的手册、还有原理图和PCB,说起来都是泪。。。

关键还是定位,对入门友好,对非专业人士友好,不局限于搞嵌入式或it的,使受众更加广泛,加上大力推广,价格低廉,自然就火了。

arduino感觉也比较类似。

RPI资源较全,而且开放,上手容易。我拿RPI做了1年的播放器,后来各种盒子出来更加方便,RPI退居二线做了下载机,不敢叫nas,usb2.0的速度实在汗颜。
后来入了国产的cubieboard,1G主频,1Gram,板载4G Flash,支持tf扩展,本意是替换播放器的,无奈社区或者板子的开发者,主力放在基于android的开发上,到最后原生xbmc播放文件还有各种问题,据说是gpu硬解的库,未完全开源,只能用android下的库,用类似wine的方式使用,如此一来还有什么效率。改做下载机倒是合适,有原生sata2,目前当值下载机。

综上,熟悉linux的,其他开发板用起来也没问题,RPI不过是上手快。

Bay Trail J1900比较不错的。ARM的东西比较适合低功耗便携之类的场景。英特尔的就另说了。不过今年英特尔发布的邮票大小的开发板还是比较好玩的。

英特尔Edison开发板,市场价格400块人民币的样子。体积很小,邮票大小。
附上原文简介:

Key technical features

At the center of the Intel® Edison board is an Intel® Atom 22nm SoC with a dual-core CPU at 500Mhz and a MCU at 100Mhz. This allows the product to collect and preprocess data via the MCU in a low power state and hand the filtered data off to the CPU for analytics. The Intel® Edison board includes 1GB of memory, 4GB of storage and dual-band Wi-Fi and Bluetooth* 4.0 for communications. It supports 40 GPIOs with multiple configuration options.

本来想买 ODROID-C1 因为配置好,还有千兆网 OTG 和更多 USB 口。

不过 Raspberry Pi 2 的 CPU 貌似更好(虽然主频低) Cortex-A7 900MHz VS Cortex-A5 1.5GHz 都是四核,不知道具体性能能差多少。官方的说法是: Up to 20% more single thread performance compared to Cortex-A5 at similar energy efficiency

鉴于树莓派的生态环境更好,还可以用一代的盒子散热等部件(其实主要是免邮),所以刚出就买了一个... 等 ODROID 出对应的升级品再入一个...

我申请了个免费的 MIPS Creator CI20,还没怎么玩,可惜是个32位的,要是64位的就更好了。

这里再次重申,raspberry pi 的主芯片不是单纯的cpu,而是soc的概念。因为bd那家奇葩芯片公司不怎么给开放资料。所以,raspberry pi的很多东西你不太好榨干。

又发现个好玩的东西。在  http://www.gizmosphere.org  这个网站上面介绍的。一个叫做GIZMO的板子。amd的x86。装linux没有问题。可以当个小计算机用。

关键是轻巧和低功耗,那个apu的功耗才4w。尺寸也很小巧。

这片amd的soc做的还不错了。只能说各自玩的东西和需求不同吧。好久没有关注开源硬件的小板子。现在倒是出了不少好玩的东西。另外,现在还有很多传感器以及rfid,nfc的模块都可以在类似的板子上面装了。真是可以拼出很多好玩的应用,比如装个rfid和nfc的模块,装好系统,写个程序。可以破解门禁之类的。

说的是ARM吗?x86的话除了价格,不是全都悲剧了?

最近还有一块arm64的板子:http://www.96boards.org

其实是一套标准。
