Dev-Kit Manufacturing Guide

PCB Fabrication and Assembly

Build the vehicle PCBs using the standalone PCB assembly guides. These guides are the canonical source for ordering notes, interactive BOMs, stencil/reflow guidance, inspection images, and PCB-specific manual assembly steps.

• Main PCB Assembly Guide
• Battery Control PCB Assembly Guide
• Flight Controller PCB Assembly Guide

This Dev-Kit Manufacturing Guide covers how the completed PCBs are installed into the vehicle during general assembly.

Harness Fabrication

Build harnesses using the standalone Harness Manufacturing Guide. It is the canonical source for nailboard diagrams, BOMs, wire prep, termination, and pinout maps.

This Dev-Kit Manufacturing Guide keeps only vehicle-side routing and installation notes, placed in the assembly steps where each harness is installed.
