: By combining the processor, memory, and control logic into a single SoC, the board reduces the need for external components and minimizes the overall footprint.

The SIS001 is a compact development board specifically engineered for . Unlike traditional Wi-Fi, where every device must connect to a central router, mesh networking allows every SIS001 board to act as a node that relays data for others. This creates a resilient network that can cover large areas without needing a massive infrastructure. Why "Free" Matters in Hardware : By combining the processor, memory, and control
SIS001 represents more than just a media repository; it is a resilient social artifact. Its ability to remain a "free board" for decades highlights the tension between centralized control and decentralized community needs. | | RTOS | Zephyr (default) – also
