Eye-Fi SD卡能够让任何数码相机摇身一变成为无线网络相机。只要你身边拥有无线网络，就能变拍边看，按下快门后即刻在电脑上查看刚刚拍摄的照片，完全无需任何连线。对于这样的产品，我们当然想看看厂商是如何在SD卡狭小的空间内塞进无线网络模块，ikontools网站就满足了我们的好奇心。

可以看到，其内部结构远比普通SD卡复杂得多，主要用料包括：

1. Atheros AR6001GL ROCm（Radio-on-a-Chip for Mobile）无线网络芯片，支持802.11 b/g，内置512KB闪存，BGA封装10x10mm。

2. 三星K9LAG08U1M NAND闪存

3. Hyperstone S4闪存控制器

4. Epic Communications FM2422集成RF前端模块

5. 仙童FAN5350同步降压转换器

6. 40MHz晶振

7. 天线（内层，几乎覆盖整个SD卡）
