Hardware Overview

XIAO nRF52840

  • Onboard
  • PinOut

Wio-SX1262

  • Onboard
  • PinOut

 

Application Scenarios

  • Meshtastic Node & Router: This ultra-compact node can function as a portable device or a stationary router to enhance the Meshtastic network.
  • LoRa/LoRaWAN Sensor: A small LoRaWAN sensor, perfect for beginners delving into LoRa/LoRaWAN.

     


    This can be paired with a GPS module (like the XIAO L76K) to track locations of logistics vehicles, animals, and valuable assets. With the long-range capabilities of LoRa (up to 2-5 km in urban settings and exceeding 10 km in rural areas), it significantly lowers the costs associated with establishing base stations.
  • The distance between two nodes has the potential to reach up to 2KM (environment-dependent).
