48 Jackrabbit (BL1800)

A.1.1 Exclusion Zone

It is recommended that you allow for “exclusion zones” around the Jackrabbit when the

Jackrabbit is incorporated into an assembly that includes other components. These “exclu-

sion zones” that you keep free of other components and boards will allow for sufficient air

flow, and will help to minimize any electrical or EMI interference between adjacent

boards. Figure A-2 shows the “exclusion zones.”
