Cracking open the latest iPod nano, DIY repair experts iFixit have laid bare the device's inner workings. Besides the larger screen and increased storage capacity, the inside is largely filled with a double-size battery; few other changes are apparent. Despite the tight packing of components, however, the seventh-generation nano is still relatively easy to work on.
Unsurprisingly, there aren't any radical changes to this new, oddly larger nano design. An ARM processor from NXP Semiconductors powers the device, though its logic board is dominated by the 16GB Toshiba NAND flash storage chip. Several Apple-branded chips appear to handle digital-to-analog audio conversion, Lightning signals, and power management. A new Broadcom Bluetooth 4.0 module adds Bluetooth compatibility while doing double duty as an FM receiver, and the touchscreen controller is a Texas Instruments IC.

The aluminum case was elongated to fit the larger 2.5" touchscreen, and all the extra space is essentially filled with more battery capacity. The new battery is 0.8Wh, slightly more than double the previous gen's tiny, 0.39Wh battery.
