Long-distance cycling events — gran fondos, gravel races, bikepacking routes, and ultra-endurance events — span dozens to hundreds of miles, making traditional radio-based support communications challenging. LoRa mesh provides an elegant solution for both safe...

T-Deck as a Standalone Communicator The LILYGO T-Deck is one of the most distinctive devices in the mesh radio ecosystem. Unlike the vast majority of mesh nodes, which function as radio bridges and depend on a paired smartphone for any human interface, the T-D...

nRF52840 vs ESP32: Architecture Comparison for Mesh Operators When selecting hardware for a mesh deployment, the choice of microcontroller architecture is often the single most consequential decision you will make. Two families dominate the mesh radio space: N...

SX1262 vs SX1276: Why It Matters Nearly every mesh radio node sold today uses one of two LoRa radio ICs from Semtech: the older SX1276 or the newer SX1262. Both chips implement LoRa spread-spectrum modulation and are outwardly similar, but their performance ch...

T114 and T3-S3: New Hardware for 2025-2026 LILYGO's 2024-2025 product refresh introduced two boards that are quickly becoming community favourites: the T114 and the T3-S3. Both pair an SX1262 LoRa radio with a modern microcontroller, but they target distinctly...

Solar panel sizing depends heavily on your geographic location. The same 5W panel produces dramatically different energy in Portland, Oregon vs. Phoenix, Arizona. This guide walks through climate-specific sizing calculations. Peak Sun Hours by Region Peak Sun...

The charge controller is the brain of your solar power system — it manages battery charging, prevents overcharge and deep discharge, and in MPPT controllers, optimizes power extraction from the solar panel. Choosing the right charge controller significantly af...

Accurate power consumption measurements help you design realistic solar power systems and understand why your battery life differs from specifications. This page covers practical measurement techniques for mesh node operators. Measurement Tools USB power m...

Florida and the Southeast Florida presents one of the most distinctive operating environments for mesh radio networks in North America. A combination of flat terrain, aggressive humidity and salt air, an active amateur radio community, and the ever-present rea...

Texas and Gulf Coast Networks Texas presents mesh radio operators with some of the most varied deployment challenges in North America -- a state so large that its four major metro areas each warrant their own network strategy, while vast rural expanses in the ...

Finding local mesh users is one of the most common early questions — and one of the most important, since a single node is useful but a community is transformative. Start With Online Resources meshmap.net — The global Meshtastic community map. Zoom to your...

Starting from zero is actually common — most community networks were started by one person who got tired of being alone on the mesh and decided to fix that. Here's how to bootstrap effectively. The Minimal Viable Network You need at least 2 nodes to have a ne...

The short answer: yes, with some limitations. Both platforms are open source with licenses that permit commercial use, and the ISM band spectrum they operate on allows commercial activity. Here's what you need to know. Software License Considerations Meshtast...

The stock antenna that comes with most LoRa boards is a rubber duck (flexible whip) antenna, typically 3-5 dBi gain. For many use cases, this is adequate — but upgrading to an external antenna is one of the most cost-effective improvements you can make. When ...

Antenna gain specifications use two different reference points — dBi and dBd — and confusing them leads to incorrect link budget calculations. Here's what each means and how to convert between them. The Reference Antennas dBi (decibels relative to isotropi...
