Digi RF Modules produce a very small amount of noise. All Digi radio modems have been tested and certified to comply with the FCC part 15 regulations which measure the interference that the radio can cause to other devices.
We have only seen this noise be significant in thermocouples or hypersensitive devices detecting small signals. Our customers have mounted DSPs or microprocessors underneath our OEM Module without any problems.
