AVR microcontroller. Only the current version of the IAR compiler is supported for the RM2.4 Library. The RM2.4 Library for the MICRO-RM2.4 Radio Module will be released in the 3rd quarter of 2015. These library files will be available at www.MicroRidge-RM.com. -
Page 19: Application Board Design
A common rule of thumb is to make the via spacing less than λ/20 at the maximum operating frequency. For the MICRO-RM2.4 Radio Module, the wavelength at 2.4 GHz is 125 mm and the maximum via spacing would be 6.25 mm. - Page 20 Low profile enclosures might affect antenna performance. § Avoid placing high profile components next to antenna. § Radio module should not be placed next to other electronics which might interfere with the 2.4 GHz frequency band.
