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`.
