Building a Solar Node – Rak Unify Box
WARNING: THIS IS A WORK IN PROGRESS AND IS NOT FINAL. DO NOT FOLLOW THIS UNTIL THIS MESSAGE IS REMOVED.
This guide walks through assembling a solar-powered MeshCore repeater using the RAK Unify Box enclosure. Follow each step carefully for a reliable and weatherproof build.
Assembly Steps
WARNING: Always ensure a LoRa antenna and the Bluetooth antenna are attached to the RAK board before powering it on. Powering without antennas can permanently damage the board.
1. Unbox all components and place them aside.
* Tip: Try not to misplace the small screws and fittings — they’re easy to lose.
2. Mount the RAK backplate into the box with the four provided screws.
3. Drill two holes: one for the N-type antenna mount and one for the drain plug.
* Use a step drill bit for clean holes.
* Finding the top of the box:
- Flip the box onto its back.
- Locate the mount hole marked "1" — this is the top.
* Drill slowly, one step at a time. Test-fit the N-type connector after each step until it fits snugly.
* Repeat the same process on the bottom of the box for the drain plug.
4. Attach both the N-type antenna mount and the drain plug.
5. Connect the N-type antenna to the LoRa IPEX connector on the RAK19003 board.
6. Mount the Bluetooth antenna to the side of the box using the included double-sided tape.
7. Connect the Bluetooth IPEX to the RAK19003 board.
8. Connect an antenna to the N-type connector, then flash and configure the RAK unit following Configuring a Repeater.
9. Mount the RAK unit onto the backplate, see picture below for what it should look like at this step.
10. Connect the JST PHR-2 cable to the RAK19003 battery plug, ensuring correct polarity (many JST cables are wired incorrectly).
11. Connect the other end of this cable to the CHG side of the VoltaicEnclosures Li-ion PCM.
12. Slide a piece of heat-shrink tubing over the cable large enough to cover the PCM before connecting the battery.
13. Connect the LiPo JST PHR-2 cable to the BATT side of the PCM, again ensuring polarity is correct.
14. Heat-shrink the VoltaicEnclosures Li-ion PCM so the entire board is covered.
15. (Optional) Secure the PCM to the backplate using double-sided tape. It can also float freely inside the box if preferred.
16. (Optional) Secure the battery to the backplate with double-sided tape or mounting hardware.
17. Fit the rubber seal into the groove around the edge of the front plate of the box.
18. Connect the solar panel wire from the front plate to the RAK19003.
* Be careful not to let the seal fall out of place while connecting the solar panel wire.
19. Join the front and back plates together and fasten them with the six screws.
* Tighten securely to maintain the weatherproof seal.
