NXP FRDM-CR20A

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 NXP FRDM-K64F.
