CPU+GPU+RAM:按照Raspberry Pi的配置表,我们应该能在板子上找到一颗Broadcom出品的,集成了GPU和CPU的BCM2835芯片。其实呢,即便你左看右看上看下看,也不会找到它的。对比Raspberry Pi的实物图和框图,我们会在CPU这个位置发现了一颗SUMSUNG的芯片(不同生产批次的Raspberry Pi,芯片厂商可能不一样),如图6所示,这是内存(RAM)的位置,而BCM2835则以PoP(Package on Package)封装的形式“潜伏“在内存颗粒的下面。什么是PoP封装呢,图7所示是一个PoP封装的示意图,供大家参考。 ![](http://files.note.sdo.com/M5cEN~kg7Fg9nM24s00O6R) *(外链图片未本地化)* 图6 CPU位置发现了一颗SAMSUNG的芯片 ![](http://files.note.sdo.com/M5cEN~kg7FfVnM24s00O6G) *(外链图片未本地化)* 图7 PoP封装示意图及实物图 2. MicroUSB充电口(见图8):这是为Raspberry Pi提供电源的一种重要方式。用过智能机的“亲们”都知道,MicroUSB是很脆弱的,因此建议在拔插的时候,动作一定要温柔一点。 3. SD卡槽:Raspberry Pi的操作系统就安装在SD卡上。SD卡的选择也是有讲究的,如果选择不当就会有不兼容的问题。有关SD卡的选型,请大家关注《无线电》后续的文章。 4. Composite RCA接口:复合RCA接口,也就是俗称的AV端子。Raspberry Pi是可以输出AV模拟信号的,图9所示是笔者使用Raspberry Pi RCA进行输出的示意图。 (未完......) (全文请见《无线电》第9期) ![]() ![]() [【分享】Raspberry Pi](thread-5795-1-1.html)
