Board Comparison Table The table below covers the most widely deployed boards for LoRa mesh networking as of 2025–2026, across both Meshtastic and MeshCore platforms. All TX power figures are nominal maximum; actual radiated power depends on antenna gain and a...

Board Selection by Use Case Use this guide to narrow down board options based on your deployment scenario. Every use case has a different set of priorities — power consumption, form factor, display needs, and software support all vary. Start with your primary ...

MeshCore Routing Architecture MeshCore uses a demand-driven path-based routing protocol. Unlike Meshtastic's flooding approach, MeshCore establishes explicit routes before sending data. Route Request (RREQ) Mechanism Route discovery works in four steps: W...

This page covers MeshCore's packet encryption as verified from docs/packet_format.md and src/Utils.cpp in the official MeshCore repository. Encryption at the Packet Level Each MeshCore message packet is protected by AES-128 encryption followed by a 2-byte HMA...

MeshCore Network Topology Best Practices Backbone vs. Client Layer A well-designed MeshCore network is organized into two distinct layers: Backbone layer: dedicated repeaters placed on elevated sites with clear line-of-sight between them. These form the ro...

Protocol Comparison Reference This page provides a technical comparison between MeshCore and Meshtastic — the two most widely deployed open-source LoRa mesh networking platforms. Both run on similar hardware and serve similar goals, but make very different des...
