| 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`. |
