Build process

  1. Print or prepare the board holder

    Use the linked RAK19007/RAK4631 holder or mount the electronics on insulated standoffs.

  2. Prepare the enclosure

    Plan the antenna bulkhead, USB-C pass-through, solar lead and optional magnetic mounting points before drilling.

  3. Install the radio and RF path

    Seat the RAK4631 securely and connect the U.FL/IPEX pigtail to the N-female bulkhead with minimal strain.

  4. Add power hardware

    Install the PCM/power components, connect the solar input and verify battery polarity before powering the radio.

  5. Weatherproof

    Seal the cable entries and RF connector. Keep the USB-C bulkhead gasket properly compressed.

  6. Deploy

    Attach the ALFA antenna vertically, place the panel for good sun exposure and test charging over multiple daylight cycles.

Build notes

  • The linked AtlaVox USB-C bulkhead is tagged with the No Bars Club affiliate reference.
  • Magnets are convenient on steel surfaces, but use a mechanical backup for exposed or elevated installs.
  • Avoid placing the battery where it will sit against a hot enclosure wall in direct sun.
