Dev kit adds Bluetooth and 802.15.4 connectivity

NXP has introduced a development kit which adds Zigbee or 802.15.4 connectivity to designs.

Called FRDM-KW24D512, it is based around the MKW24D512 microcontroller which has a 2.4GHz IEEE 802.15.4 radio transceiver and an ARM Cortex-M4 processor.

“The kit contains two boards, enabling point-to-point out of the box connectivity. It has a diverse reference design with all the necessary I/O connections for use as a self-contained board or for connection to an external application,” said element14, which is supplying it.

Board have integrated inverted F-type antenna and SMA RF ports, and alongside the hardware, there is software support for Thread, ZigBee Pro, 802.15.4 MAC and SMAC. There is also the Kinetis Software Development Kit – the MUC is a Kinetis W chip.
