Meshtastic guides

These guides answer the questions people ask most often about Meshtastic, from the first power-on to building a solar repeater. Each one is built on the official Meshtastic documentation, the makers' specifications and the rules of national radio regulators, and each lists its sources with the date they were checked.

If you are new, read them roughly in this order: what Meshtastic is, how to set it up, which frequency is legal in your country, and how far it will reach. After that, the guides on presets, roles and antennas explain the settings that decide whether a local mesh works well or chokes on its own traffic. Buying guides and comparisons help you choose hardware, and the tools at the end do the maths on range and battery life for your own setup.
