More experienced RF designers may wish to do a significant number of RF evaluation tests or implement an external customer defined antenna. To allow customers the freedom to pursue these design objectives, NXP offers the 1320XRFC, or RF daughter card. This daughter card works with the HCS08 and ColdFire MCU evaluation boards. A single ended F connector antenna is included as well as a connector for an external antenna. The board offers an exceptional line of sight range of approximately 300m.
