SS01SS20

ss01ss20 is a fictional modular embedded computing platform used in technical writing and education to illustrate concepts of hardware modularity. The designation combines two model identifiers, SS01 for the base processing core and SS20 for an expansion/interface family. It is presented as an open-reference design rather than a commercially released product, intended to support classroom demonstrations, prototyping, and design studies.

Hardware architecture: The platform is described as a two-module stack. The SS01 base module provides a compact system-on-chip, integrated memory, and essential I/O. The SS20 expansion adds additional GPIO, sensors, and connectivity options. The modules use a stackable, breadboard-friendly form factor with standard 40-pin headers and compatible mezzanine decks. Typical configurations specify 256–512 MB of RAM and 2–16 GB of flash storage, with 5V USB-C power and modest power use suitable for battery-powered experiments.

Software and tooling: ss01ss20 is accompanied by open-source firmware and development tools. It is said to support Linux-based firmware, a bootloader, and a hardware abstraction layer to aid cross-platform development. A lightweight RTOS option is described for real-time tasks. The project emphasizes accessibility and education, with tutorials and example projects in a public repository.

Development and reception: Originating in technical discussions around 2020, the design is used in school curricula, maker spaces, and hypothetical case studies to teach modular design, system integration, and prototyping workflows. In these contexts, it is praised for clarity and flexibility but criticized for lack of a real-world supply chain and official long-term support.
