How does your team use Trello?

[DubstepLion1]

My concern is that if I start making boards for individual projects like a robot, how would I organize smaller projects or miscellaneous tasks? Our team structure somewhat complicates this because we have two divisions, Engineering and Business, and each of these divisions have several departments (e.g. Programming, CAD, Media, Outreach). Some departments have projects within themselves, but I don't want to deal with having too many boards.

We were planning on integrating it with Slack, too, but I'll make sure to look these other software.
