Currently there are two RCM5400W production models. Table 1 summarizes their main
features.
NOTE: There is a special version of the RCM5400W RabbitCore module for Japan. It is
functionally identical to the standard RCM5400W module and uses the same compo-
nents, but has been assembled to meet the Japan regulatory requirements. Be sure to
order the correct version for the market where you plan to use the RCM5400W. The
two versions can be distinguished by the labels on the RF shield as shown below.
