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

All-in-One Devices
Handheld / Portable
- WisMesh Pocket
Fully integrated handheld Meshtastic device with built-in battery, display, GPS, and enclosure. Good for mobile use, field testing, and users who want a polished, ready-to-use experience. - WisMesh Pocket Mini
Lighter, smaller, and cheaper than the Pocket, with no built-in display or GPS. Well-suited for pocket carry or bag-mounted use when size and weight matter. - Heltec v4
A newer ESP32-S3-based development board with improved performance and USB-C. Requires a case, battery, and antenna, but offers flexibility for DIY builds and experimentation. - Heltec v3
An inexpensive, widely used Meshtastic board with built-in display and good community support. A common starting point at Root Access, especially for learning and prototyping.
Fixed Solar Setups
- WisMesh Repeater System
A complete, outdoor-rated solar-powered Meshtastic repeater designed for permanent installations. Intended for rooftops, towers, and remote locations where continuous operation and reliability are required. - WisMesh Repeater Mini
A rugged solar repeater suitable for semi-permanent installs in remote areas. Useful for extending coverage, filling gaps, or bridging separate mesh clusters.
3D Printable Cases
- WisMesh Pocket V2 case
The default enclosure for the WisMesh Pocket, for when you want different colors, materials, or print finishes beyond the stock options. - @TonyG on Printables
A collection of well-designed cases that cover many popular Meshtastic boards and configurations. - Search "meshtastic" on Printables.
Community-created printable cases, mounts, and accessories for a wide range of Meshtastic hardware. - Search "meshtastic" on MakerWorld.
Additional community-designed enclosures and accessories, often optimized for Bambu printers and newer board revisions.
