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.
 
Hardware¶
- MCR20AVHM - Low-power 
- High-performance 2.4 GHz IEEE 802.15.4 compliant transceiver 
 
- Connectivity - PCB inverted F-type antenna and SMA RF port 
- Arduino compatible 
 
- Power Management - Programmable output power -32 dBm to +8 dBm at the SMA connector, no trap 
- Receiver sensitivity: –102 dBm, typical 
 
- Components - Minimum number of matching components and external balun 
- 1 RGB LED indicator 
- 2 pushbutton switches

Programming¶
Set -DSHIELD=frdm_cr20a when you invoke west build. For example:
# From the root of the zephyr repository
west build -b frdm_k64f samples/net/wpanusb -- -DSHIELD=frdm_cr20a
