9The Freedom development board platform supports the MCR20A 2.4GHZ wireless
10transceiver. The FRDM-CR20A evaluation board is a small, low-power,
11cost-effective reference design for the MCR20A transceiver in a shield form
12factor, compatible with existing Freedom development platforms, such as
13:ref:`frdm_k64f`.
