今天官网公布了即将对PI的电路进行更新，其中：

Additional I/O Expansion
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.
This GPIO allocation provides access to one of:
SDA0, SCL0 (Operating independently of P1 SDA1, SCL1); or
PCM_CLK, PCM_FS, PCM_DIN, PCM_DOUT or I2S; or
Four GPIO signals.
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……

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

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。
