Crux usage
Section titled “Crux usage”An original firmware environment encountered in the RAK4631WisBlock Core module combining a Nordic nRF52840 microcontroller and an SX1262 LoRa radio.Crux usage: The module used as a MeshCore USB Companion in the Atlas Bridge recovery campaign.Open full definition fleet before migration to MeshCoreAn open-source, off-grid mesh communications system that uses LoRa-capable nodes to relay messages across a network.Crux usage: Crux uses MeshCore as a resilient public and fallback communications layer for field nodes, mobile diagnostics, and selected sensor or Daymark events. Private Crux operational data remains separately governed.Open full definition.
