Sometimes we’re designing circuit boards and electronics right down at the level of individual transistors. And sometimes it’s the off-the-shelf single board computer that gets the job done. With Modulus, so much of their amazing functionality is buried deep in their proprietary software running on their Linux PC, our job was to make sure that all the parts fit in the box, didn’t overheat, and didn’t pull too much current. And we specified the power supplies to keep it running while designing the wiring harnesses that hooked it all together.
