Upgrade paths

RAM

Soldered directly to the board, either 512 MB or 1 GB depending on the production SKU · First ARM-based XO redesign, a major power draw improvement over the VIA-based XO-1.5.

LOCKED

storage

SD card slot for expansion alongside the fixed 4 GB or 8 GB internal NAND · Internal flash is soldered but the SD slot remains the easy path to more space in the field.

EASY

battery

Standard user-removable LiFePO4 pack, no tools · Kept the tool-free latch design of earlier XO models for classroom swaps.
