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