The board is interesting in that it is has a single layer of conductive traces connecting all the components. Contrast this to modern circuit boards, which can sometimes have eight [!] PCB layers.
  • The board is interesting in that it is has a single layer of conductive traces connecting all the components. Contrast this to modern circuit boards, which can sometimes have eight [!] PCB layers.

  • The larger components on the board include:

  • RF modulator

  • Buzzer

  • ICs provided by Texas Instruments. These 16 pin DIPs are quite the departure from TI's OMAP 3630 found in the Droid 2. The logo is still just as cool, though.

有趣的是,这块电路板用单层的导电迹线吧所有的元器件连接起来。对比现代的电路板最多能有8层!

比较大的元件有:

射频调制器

蜂鸣器

德州仪器提供的芯片。这些16针脚的双列直插式外壳,跟现在在Droid2 上的德州仪器OMAP 3630完全不是用一个时代的产品,但商标还是一样的Cool.
