15.System Integration

Assignment

Design and document the system integration for your final project

Summary

I worked on the packaging for TrailNAV: printing the enclosure, checking the screen and solar-panel fit, and soldering wires for later integration. This gives me a physical enclosure to build around. The navigation firmware, final PCB arrangement and complete system test remain to be documented.

Subsystems

1, TrailNav cover

I started designing the TrailNAV cover to create an attractive front page that represents the device's purpose as a solar-powered off-grid navigation system for outdoor exploration and waypoint tracking

Added the solar panel to highlight the solar-powered charging capability.

Next, I started slicing and printing all the TrailNAV parts. The 3D were prepared using slicing in creality and then printed to create the enclosure components needed to assemble and protect the device's hardware

I sliced and printed the enclosure parts shown here. My earlier text listed 200°C for both the nozzle and the bed; the bed value was an error. I need to recover the saved slicer settings before giving the actual temperatures for this enclosure print.

After printing, I started fitting the screen and the solar panel into the enclosure to make sure that all the printed parts were correctly sized and aligned. This step was important to verify that the components fit properly and that the enclosure could securely hold them before the final assembly

Next, I soldered wires that will connect to the microcontroller for further testing and integration

Bringing it together as a finished product

The screen and solar panel fit their printed openings, and the assembled enclosure gives me a way to check the external form. I still need an internal arrangement showing dedicated mounts for the PCB, battery and charging circuit, with routed wires and suitable connectors. My final project page records the planned interfaces and outstanding checks.
