|  | 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 | 
|  | :zephyr:board:`frdm_k64f`. |
