Our Equipment

This page collects example Freq51 node builds and their approximate coverage maps. Use them as starting points, not as required designs: hardware, software, power systems, and placement must suit the site. Our infrastructure commonly uses low-power nRF52-based nodes, Femtofox nodes, and Nebra-based builds with 1 W radios. Router deployments require an appropriate RF filter; filtering is optional for non-infrastructure nodes. Coordinate any router deployment with the community before building or placing it.

Here is a list of hardware many of us use - Freq51 Hardware

NRF52 Mobile Node Example

The SenseCAP Card Tracker T1000-E is a compact, NRF52-based mobile Meshtastic node designed for lightweight, on-the-go use. Built around the nRF52840 MCU and an LR1110 LoRa transceiver, it combines low-power mesh communication with integrated GPS/GNSS inside a rugged, credit-card-sized enclosure. Its small size, IP65 rating, and simple charging interface make it ideal as a mobile, personal, or asset-tracking node within an NRF52-based mesh network.

Pros

  • NRF52 Platform (nRF52840): Aligns well with NRF52-focused mesh architectures.
  • Integrated GPS: Provides location reporting with no external modules required.
  • LoRa (863–928 MHz): Compatible with Meshtastic regional configs.
  • Ultra-portable: ~credit-card size, lightweight, easy to carry or mount.
  • Rugged: IP65 dust/water resistance for outdoor mobility.
  • Fully supported by Meshtastic firmware.

Cons

  • Battery life depends on GPS + reporting interval (700 mAh internal battery).
  • LR1110 radio has partial compatibility limits with older SX127x nodes (mainly receiving).
  • Lower TX power and internal antenna = less range than full-sized infrastructure nodes.
  • Not suitable as a router node — best for handheld/mobile deployment.

NRF52 Static/Roof Node Example

  • RAKwireless WisBlock Meshtastic Starter Kit US915 Base RAK19007 + Core RAK4631
  • ABS 7.9“ x 3.9“ x 2.8“ enclosures are a great size/price/quality (or similar).
  • Butyl tape OR LEXEL seals antenna passthroughs and is great for making outer seals as lexel sticks to itself (don’t block included gaskets).
  • Adafruit bq25185 USB / DC / Solar Lithium Ion/Polymer charger modules are handy for charging packs while radios are disconnected/in storage and its a great small MPPT (remove charge LED for small solar if needed).
  • “Soshine” solar panels with regulated 5 V output are convenient and include a mounting pole.
  • UV-protect plastics & seal passthroughs: LEXEL has worked well.
  • Use the battery connector as a service “switch” inside; add an external waterproof switch only when tool-access enclosures demand it.
  • Add a small weep hole on the bottom for pressure equalization and drainage. This is also useful if you have weather sensors. Add a small fabric baffle and place the sensor behind it. We like Bosch BME680’s for weather data.
  • Lube gaskets (e.g., silicone grease) to reduce drying/cracking and improve seals.
  • After many trials, Alfa 5 dBi omni antennas have been a solid value: short (less wind load), N-male fits through-panel connectors, reliable wide beam.

We are going to fill out standard builds as we improve the documentation. Feel free to drop by the discord and suggest yours

Femtofox Node Example

Femtofox nodes are commonly used for low-power fixed deployments. A complete example should include the radio model, enclosure, antenna, power system, firmware version, and a photo or site-survey result. If you operate a documented Femtofox build, share it through the Contribute page.

Nebra Node Example

PiZero Node Example

A Raspberry Pi Zero 2 W can be a compact option for a fixed node when paired with supported radio hardware, a reliable power source, and a weather-appropriate enclosure. See the Nebra Miner Guide for a more complete Linux-based reference build.

Bird House Node Example

Birdhouse-style enclosures can be a practical way to conceal and weatherproof a node. Use a non-metal enclosure, keep the antenna clear of obstructions, protect cable entries from water, and make sure the enclosure can be serviced safely.

Tips for placement

  • Test the location before installing permanently.
  • Height and line of sight usually matter more than transmit power.
  • Keep antenna feed lines short and use weatherproof connectors.
  • Use a CLIENT role by default; coordinate before deploying a ROUTER.
  • For outdoor installations, plan for grounding, lightning protection, drainage, and maintenance access.

See Coverage and Maps and the Router Deployment Guide before planning a permanent installation.
