The FRDM-KW40Z is a low-cost development platform enabled by the Kinetis® W series KW40Z/30Z/20Z
(KW40Z) family built on the Arm® Cortex®-M0+ processor featuring an integrated 2.4
GHz transceiver supporting Bluetooth® Smart/Bluetooth® Low Energy v4.1 and/or
IEEE® 802.15.4-2011 standards.
The FRDM-KW40Z kit contains two boards, enabling point-to-point out of the box connectivity. Each board can be
configured as a Freedom development board or as a Freedom shield. The FRDM-KW40Z hardware is form-factor compatible
with the Arduino® Rev3 pin layout, providing a broad range of expansion board options.
The FRDM-KW40Z features a highly-sensitive, optimized 2.4 GHz radio with PCB F-antenna which can be bypassed for
connection to test equipment via SMA connection, multiple power supply options, push and capacitive touch buttons,
switches, LEDs and integrated sensors.
