The CrowdSwitch is the cornerstone of our efforts to bring IsoGrid to the world.

It is a future hardware product in early development. It’s goal is to be the first concrete implementation of the IsoGrid protocol stack. When connected together, the switches form a streaming, scalable, mesh network.

Our initial plan is to give low cost (or free) CrowdSwitches to people living in extremely high-density urban communities, who otherwise don’t have access to networks. The best funding model still isn’t clear, but we intend to build it within a 501(c)(3) organization to make our altruistic motives super clear.

  • 4-port auto-configuring switch
    • 3x RJ45 ~100 Mbps full-duplex ethernet PHY with 1ms worst-case switching latency
    • 1x internal SPI connection to an onboard SoC with 8ms worst-case switching latency
  • The core of the switch is an xCORE-200 XL216-512-TQ128
  • Onboard SoC with ~512MB of RAM, ~4GB of flash, and ability to create a wireless hotspot
  • Target (bulk) BOM cost is ~$20

The Wi-Fi part will be able to work in one of two modes:

1. Providing Internet access to a user
2. Connecting to a regular Wi-Fi Internet access point

The IsoGrid formed by the interconnected mesh of CrowdSwitches provides a redundant multi-path backbone to connect nodes operating in Mode #1 to nodes operating in Mode #2.
