This LaunchPad™ speeds development with a Bluetooth® Low Energy (BLE) connection using the CC2640R2F or CC2640R2L devices. The compatible SDK offers a fully qualified Bluetooth 5 protocol stack for single-mode BLE applications supporting high speed mode and example Bluetooth 5 coded physical layers (PHY) for long range mode testing. A Bluetooth 4.2 stack is also available.

The FRDM-KW41Z is a development kit enabled by the Kinetis^® W series KW41Z/31Z/21Z (KW41Z) family built on Arm^® Cortex^®-M0+ processor with integrated 2.4 GHz transceiver supporting Bluetooth^® Smart/Bluetooth^®Low Energy (BLE) v4.2, Generic FSK, IEEE^® 802.15.4 and Thread.

The FRDM-KW41Z kit contains two Freedom boards that can be used as a development board or a shield to connect to a host processor. The FRDM-KW41Z is form-factor compatible with the Arduino^® Rev3 pin layout for more expansion options.

The FRDM-KW41Z highly-sensitive, optimized 2.4 GHz radio features a PCB F-antenna which can be bypassed to test via SMA connection, multiple power supply options, push/capacitive touch buttons, switches, LEDs and integrated sensors.

The FRDM-KW41Z platform is now supported by Arm^® Mbed^™ OS and Zephyr^™ OS, both open source embedded operating systems for developing the Internet of Things.
