Hardware Overview

LoRa mesh networking runs on compact radio devices — sometimes called "nodes" — that broadcast and receive radio signals in the 915 MHz band (US/Canada). All you need is a compatible device, a smartphone, and the appropriate app for your chosen platform.

Types of LoRa devices

Handheld / portable nodes

Small devices (roughly deck-of-cards size) that pair with your phone via Bluetooth. These are the most common starting point. Some have a small screen; others are screen-less and rely entirely on the app.

Keyboard devices

Standalone devices with a built-in screen and keyboard, allowing you to send and read messages without a smartphone. More expensive but fully self-contained.

Fixed / solar nodes

Weatherproof nodes designed to be mounted outdoors — on a rooftop, tower, or hilltop — and powered by solar or mains power. These serve as repeaters, extending network coverage for everyone nearby.

What to look for when buying

• 915 MHz support — required for the US/Canada. Some devices sold internationally are 868 MHz (EU) — verify before purchasing.
• MeshCore or Meshtastic compatible — check that your chosen firmware runs on the hardware. Most popular boards support both.
• Antenna connector — ensure the device has an external antenna connector or a good built-in antenna. A quality antenna makes a significant difference in range.
• Battery — built-in rechargeable batteries vary widely in capacity. Larger capacity means longer runtime without charging.

What it costs

There are no subscriptions, no airtime fees, and no carrier contracts. Hardware is a one-time cost.

Is it legal in the US?

Yes. Both MeshCore and Meshtastic operate on the 915 MHz ISM band, which is designated license-free by the FCC under Part 15 rules. No amateur radio license is required. Standard devices are compliant with US regulations.
