Linux can run on only 4MB of SRAM — Azure Sphere and SudoMaker's X1501 Pico show off the extremes of Linux's small-scale potential
Linux, thediscerning user’s choice, is famous for its ability to scale down to a minuscule size. Here to prove it are two itty-bitty modules running Linux with only single-digit megabytes of RAM, displayed in a classic example of Twitter oneupmanship.
