Variants

Storage

4 GBBase storage configuration shipped to most deployments.

8 GBHigher-capacity flash configuration offered alongside the 4 GB model.

Upgrade paths

RAM

1 GB soldered directly to the board, quadruple the XO-1's 256 MB · Fixed at manufacture like its predecessor, but the jump to 1 GB removed the swap-thrashing that plagued the XO-1 under Sugar.

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

CPU

Same VIA C7-M silicon across all units, clocked between 400 MHz and 1 GHz · Clock speed was tuned in firmware for battery life, not user-adjustable in the field on deployed units.

LOCKED

battery

Standard user-removable LiFePO4 pack, no tools · Kept the XO-1's tool-free latch design for classroom swaps.

EASY

other

Entire chassis opens with a single captive screwdriver-friendly design, documented in OLPC's public service manual · Same field-repairable philosophy as the XO-1: a teacher with minimal tools can get inside, no proprietary fasteners.
