官方放出了Model B 2.0的电路图。简要翻译下帖子：
我们非常高兴万博网页版登陆页派modelB 2.0版的电路图现在可以提供下载。
这一电路图描述了新版本万博网页版登陆页派的关键的变化。大家要注意到我们目前还没有使用额外的信号来增加连接器，扩展版的开发者们可以继续将以下针脚作为DNC（不需要连接）：pin4，9，14，17，20和25。

Model B revision 2.0 schematics
Posted on October 22, 2012 by eben
We are pleased to announce that schematics for the revision 2.0 Raspberry Pi Model B are now available here.
This post describes the key changes introduced in the new board revision. Note that although we have not yet exercised our option to add additional signals to the expansion connector, developers of expansion boards should continue to treat pins 4, 9, 14, 17, 20 and 25 as DNC (do not connect).
