An open-source, off-grid, decentralized, mesh network built to run on affordable, low-power devices. We use it for local experimentation, emergency-ready comms, and community-scale networking.
What is Meshtastic?
Meshtastic is an open-source project that enables long-range, low-power communication using inexpensive LoRa radios. Devices form a mesh network that works without internet, cell service, or centralized infrastructure.
Messages hop from node to node, extending range automatically. Power consumption is low enough to run for days or weeks on battery.
This makes Meshtastic useful for:
- Community-scale communications
- Disaster and outage scenarios
- RF experimentation and learning
- DIY hardware projects
