What’s inside the iPad?

Most people would never dream of taking apart a $500 toy the very first day of buying. But Do-it-yourself website iFixit, which publishes self repair guides of various kinds of gadgets, had to - it’s their job. Yesterday they they posted a full teardown of the iPad accompanied by several high quality images of the process. Some of the things they discovered are:

  • The display assembly and rear case both weigh 350 grams each, meaning weight distribution front-to-back is exactly 50/50.
  • There is a large void in the upper right corner of the WiFi-only iPad. This is where the 3G chipset will live in the 3G-enabled iPads.
  • The battery (actually two batteries hooked in parallel) takes up most of the iPad's internal volume. It's a 3.75 Volt, 24.8 Watt-hour battery; by comparison, the iPhone 3GS has a 4.51 Watt-hour battery, while the MacBook Air's battery is 40 Watt-hours. The battery weighs 148 grams, 13 grams more than the entire iPhone 3GS.
  • The display data cable connector is the same style as that used on Unibody MacBooks
  • The logic board itself takes up very little of the iPad's volume.
  • The iPad has 512 MB of RAM.
  • The Broadcom WiFi 802.11n + Bluetooth chip appears to be significantly larger than the chipset used in the iPhone. This possibly explains the lengthened bottom portion from the leaked photos of what's supposedly the next-gen iPhone's display.
  • The WiFi antenna, located behind the Apple logo on the rear case, is either similar or identical to the antenna used in the iMac.
