Build process
- Bench-test the radio
Flash and configure the RAK hardware before installing it in the enclosure. Confirm Bluetooth/USB access and radio operation.
- Lay out the enclosure
Dry-fit the board, battery holder, RF bulkhead and cable glands. Keep RF cable bends gentle and leave access to USB/reset controls where possible.
- Drill and mount
Install the N-type bulkhead, glands and CCTV mounting hardware. Deburr openings before installing seals.
- Connect RF and power
Attach the IPEX/U.FL pigtail carefully, connect the battery system and route the solar lead through a waterproof gland.
- Seal the enclosure
Apply silicone around penetrations as needed and use self-fusing silicone tape on outdoor RF joints.
- Deploy and test
Mount the node with the antenna vertical, confirm solar charging, then run range/message tests before leaving it unattended.
Build notes
- Do not transmit without a properly connected antenna.
- CCTV arms make it easier to aim the solar panel and position the enclosure away from obstructions.
- Inspect outdoor seals periodically, especially after freeze/thaw cycles.
