Develop electronics and mechanics

Electrical and physical design work can progress together.

See the current design

Engineers review project changes and status in the browser.

Keep decisions with the work

Example

An enclosure that fits the board

Flux keeps board mounting holes and connector positions aligned with the enclosure openings. Engineers review both parts as one device.

Built for teams
