悲剧啊，买早了，Pi 电路板将更新，I2S有望了！

今天官网公布了即将对PI的电路进行更新，其中：

1. Additional I/O Expansion
3. To utilise GPIO signals released by the removal of the version identification links, a new connector site P5 has been added. This carries the four GPIO signals [BCM2835/GPIO28 – BCM2835/GPIO31] named GPIO7 – GPIO10 respectively, along with +5V0, +3V3 and two 0V. Currently this connector is not populated.
5. This GPIO allocation provides access to one of:
7. SDA0, SCL0 (Operating independently of P1 SDA1, SCL1); or
8. PCM_CLK, PCM_FS, PCM_DIN, PCM_DOUT or I2S; or
9. Four GPIO signals.
10. This connector is intended to be a suitable attachment point for third-party clock and audio codec boards, and is pinned to be mounted (ideally) on the underside due to connector clash. Pin 1 is marked with the square pad (top left – looking from the top).

但是悲剧啊，我们想要好声音的人都买早了……

还没有买 正要准备买来着。。。

再买一个呗，又不贵

本来就打算再买一个，这下正好。

恩，改版修复了很多问题，而且增加了定位孔方便装壳了 ，不过什么时候出来尚不可知呀

英国已经有人买到2.0版的了

不过好多GPIO的pin都互换了

刚好想买，观望一下，会啥时候出来呢

.........这.......这不科学啊！我才刚买啊！！！！

We don’t believe that the changes are large enough to make it worth “holding on” for revision 2.0, unless you have a specific requirement to add an audio codec or you need mounting holes for some industrial application.

我们觉得，2.0版的改动还没大到值得专门去等待，除非你有对于音频解码或者定位孔的特殊需求。

嗯嗯，同意楼上~
