Application Scenarios
- Meshtastic Node&Router: An ultra-small node that can serve as a portable device or as a fixed router to expand the Meshtastic network.
- LoRa/LoRaWAN Sensor: A mini LoRaWAN sensor, ideal for beginners exploring LoRa/LoRaWAN.
For example, when combined with a GPS module (such as the XIAO L76K ), it can be used to track the locations of logistics vehicles, livestock, and valuable equipment. Thanks to the long-distance coverage of LoRa (2-5 km in urban areas and over 10 km in suburban areas), it can reduce the cost of base station deployment. - The distance between the two nodes can reach up to 2KM (subject to the environment).
