I am starting on designing a sort of HAT (like used on the RPi) for the Nvidia Jetson Nano. As I am on my third year of electrical engineering I know little to nothing about EMI and shielding. Should I (and in what degree) be concerned about EMI/RFI shielding?

A little info about the project:

  • The casing will be containing the Jetson Nano (+HAT), a Raspberry Pi, a HomePlug adapter to interface and power a device outside of the case with a coax cable, and a power converter to power the external device.
  • The HAT will provide a connection between the HomePlug device and the Nano, as well as use some AD-converters to read analog input by the user, by means of an analog stick. (0-5V)
  • The casing will be about the size of a small office-PC
  • The Jetson Nano will drive a monitor attached to the casing
  • \$\begingroup\$ What kind of motor? Also, you have a Jetson, why add an RPi? \$\endgroup\$ Sep 9 '20 at 12:00
  • \$\begingroup\$ This depends of what sort of signals you are expecting from the analog input and how accurate you need the output of the ADCs to be. What will the source of the analog input be? \$\endgroup\$

  • \$\begingroup\$ @MarcusMüller you might have misread, it will drive a monitor. And I’m using a pi for reasons, I believe that there is already software written for it or something like that. It’s out of my control. I’m only concerned about the HAT and the casing. \$\endgroup\$

  • \$\begingroup\$ @David I have edited my post. It will be an analog stick; no modulated signals, just a potentiometer. \$\endgroup\$

    \$\begingroup\$ A "please teach me all about EMI/EMC" is beyond the scope for this site both as a question and an answer. You may think that this comment is equally useless of course but it's the truth. Study is the keyword here OR ask a specific answerable question. \$\endgroup\$
