>How can you tell if a board design is good enough EMI-wise or not? I'm 100% sure this would work with no problem because I've made a worse one and it works perfectly but how can I know how much interference it would pickup from stepper motors/brushless spindles/rotary tools, etc? The prototype, which uses a daughter board for the microcontroller, doesn't seem to suffer with any of that, but I don't have a scope know for sure.
Shielding, filtering, and routing noisy traces away from sensitive traces. By skillful design and confirmation with EMI/EMC test equipment. Henry Ott's books is required reading, it explains all this, including how to test.
Also get a scope.
