  • A light color is recommended for main body, any color for the base plate is adequate.

  • No supports are needed, but a outer/inner brim may be needed for main body depending on your printer

  • Print time using on using Bambu P1S, 0.16mm, and gyroid @ %20 infill is around 5-6hrs for the entire assembly.

Assembly Instructions

  1. Add M2 heat inserts into both the main body and electronics plate

  2. If needed, solder twisted 120mm leads onto solar panel. Optionally, apply non-conductive sealant over solder points.

  3. Apply sealant around perimeter of inside of housing. Ensure to apply a light even coat to avoid any spill over.

  4. Carefully place solar panel into place. Orientation is not restricted as long as you have long enough lead to properly route.

  5. Apply light pressure to back of solar panel until sealant is dry enough.

  6. Insert and tighten SMA panel adapter (s)

  7. Insert and tighten SMA to IPX cable (s)

  8. Insert heat inserts into main body and component plate

  9. Assemble RAK Wireless board on electronics plate with 3x M2 screws

  10. Add Battery pack to electronics plate (observe proper cable orientation). Secure with velcro strap.

  11. Add Bluetooth antenna to electronics plate, feeding cable through passthrough hole. Route and plug into RAK board. If you are using external BLE antenna, skip this step.

  12. Route SMA to IPX cable for the LoRa through hole of electronics plate, plug into RAK board

  13. Place electronics plate into housing, ensuring no cables are pinched and battery/solar leads are properly routed.

  14. Secure electronics plate with 4x M2 screws

  15. Attach external LoRa antenna (and BLE antenna if applicable) 

  16. Plug battery and solar cables to RAK board.

  17. Insert 1/4-20 heat insert into base plate.

  18. Rotate base plate into main body until hand tight. Do not overtighten.
