Full Glossary A - Z A reference guide to terms used in LoRa mesh networking, covering MeshCore, Meshtastic, hardware, radio concepts, and related protocols. Terms are listed alphabetically. A ACK Acknowledgment. A confirmation packet sent by the destinat...

Hardware Overview & Buying Guide Choosing hardware for a LoRa mesh node comes down to three factors: what role the device will play (handheld communicator, portable node, or fixed repeater), what firmware you intend to run (MeshCore or Meshtastic), and your bu...

MeshCore Device Compatibility MeshCore is a lightweight mesh firmware optimised for LoRa networks. The following devices are supported as of early 2026 (the supported list changes - always check flasher.meshcore.io for the latest list before purchasing hardwar...

Meshtastic Device Compatibility Meshtastic is the other major firmware option for LoRa mesh nodes. Hardware compatibility overlaps significantly with MeshCore. Always verify at flasher.meshtastic.org before purchasing. Widely Used Meshtastic Devices DeviceMC...

Budget Devices Budget-tier devices generally cost under ~$30 (as of 2026-06-08) and can be a reasonable entry point, but they come with trade-offs: most bare boards ship without GPS, an enclosure, or a battery. Users who want a turnkey experience may be better...

Mid-Range Devices Mid-range devices ($25 - $50) add useful features: GPS, better displays, higher transmit power, lower power consumption, or more robust form factors. (Prices below are as of 2026-06-08 and shift over time.) Heltec V4 - $25 - $35 (as of 2026-...

Premium & Feature-Rich Devices Premium devices (roughly $43 - $109, as of 2026-06-08) target users who want a self-contained communicator, maximum battery life, infrastructure-grade performance, or specialised capabilities like NFC. Prices are volatile and var...

Prebuilt Solar Repeater Units Prebuilt solar nodes take the complexity out of outdoor deployments. They arrive weather-rated, often pre-flashed, and ready to mount. The trade-off is higher cost compared to a DIY build. Prices below are as of 2026-06-08 and var...

Base Station Nodes Base station nodes are designed for fixed high-site installations where maximum transmit power, receive sensitivity, and continuous power availability matter more than portability or battery life. Station G2 - ~$109 (as of 2026-06-08) The S...

Flashing MeshCore Firmware MeshCore firmware can be installed via the web flasher (easiest), with command-line flashing tools (esptool for ESP32, UF2 drag-and-drop for nRF52), or OTA (over-the-air) for updates on already-running devices. All methods are covere...

Flashing Meshtastic Firmware Meshtastic firmware is flashed via the web flasher at flasher.meshtastic.org or via the Meshtastic Python CLI. The process is similar to MeshCore but has some differences in device selection and channels. Web Flasher Open flasher...

Flashing Troubleshooting Most flashing failures fall into a small set of categories. Work through this table before assuming the device is damaged. Troubleshooting Table SymptomLikely CauseFix Device not detected by browser or OS Charge-only USB cable; w...

Parts List & Overview A DIY solar repeater can be built for roughly $90 - $140 using commodity parts (with the solar-capable Heltec V4; a stripped-down V3 build can come in lower). This build creates a weatherproof, autonomous LoRa mesh repeater powered entire...

Assembly Guide This guide assumes you have all parts from the Parts List & Overview page and have already flashed MeshCore Repeater firmware onto the node. Step 1: Test Before Sealing Before putting anything in the enclosure, bench-test the complete power cha...

Cold Weather & Winter Operation LoRa mesh nodes can operate year-round in cold climates, but cold weather affects battery chemistry, solar production, and hardware longevity. Plan for these factors before deployment. Battery Chemistry in Cold ChemistryCold P...

Choosing an Enclosure The enclosure protects your electronics from weather, UV, and physical damage. Choose based on IP rating requirements, available mounting options, and your willingness to do custom drilling and fitting. As a rule, target IP65 as the pract...

Weatherproofing Tips Even a good IP65-rated enclosure can leak if improperly assembled. (IP65 is the practical minimum for a sheltered outdoor enclosure; choose IP66/IP67 for direct weather exposure — see the canonical IP-selection guidance on Choosing an Outd...

Understanding Gain and dBi Antenna gain is one of the most misunderstood topics in practical LoRa deployment. More gain is not always better - understanding what gain actually does will help you choose the right antenna for each deployment scenario. What dBi ...
