How VION Labs approaches a device brief, enclosure and electronics design, prototype assembly and the checks that inform the next hardware revision.

Hardware starts with the place where it will operate. A wall-mounted network module, a cabinet computer and a door sensor have different mounting, cable and maintenance requirements. At VION Labs, those conditions shape the first design discussion.

## Record the installation conditions

Bring a photograph and a connection diagram to the first review. Where is power available? Can the module be disconnected for maintenance? Is there room for the cable plug and its bend? The answers become measurable requirements for dimensions, power, mounting and interfaces.

## Fit the board to the enclosure

Port locations determine enclosure cutouts. A heat sink sets a minimum lid height, and a mounting post can block a cable. Compare the board layout with the 3D model before assembly. Also check whether the chosen tools can reach every fastener during servicing.

## Build a sample that can be tested again

Check boot, interfaces and firmware updates on the first assembled unit. Measure temperature under a sustained load in the intended enclosure. Record the board revision, software build and conditions so the same test can be reproduced after a component change.

## Prepare the next revision

Give each change a reason that connects it to an observation. Keep schematics, board files, enclosure model and matching firmware together. Written retest criteria show whether the next sample actually resolves the issue.
