Hello Para,
1. The SDK_2.2_FRDM-KW41Z also includes other primary demos and all the drivers.
2. About how to use it , I recommend you use the MCUXpresso IDE, you can downlaod it at here :MCUXpresso IDE|Eclipse-based Integrated Development Environment (IDE)|NXP
then refer to the "MCUXpresso_IDE_User_Guide.pdf" install SDK , and import exmple :
- 4.4 Installing an SDK
- 6. Importing Example Projects (from installed SDKs)
(It is very simple .)
3. About KW41, there is reference manule in NXP website, of course there is data sheet,
Arm® Cortex®-M0+|Kinetis® KW41Z 2.4 GHz Bluetooth Low Energy and Wireless Radio MCUs|NXP
the Reference manual more detail , you find the describtion about peripherals:
https://www.nxp.com/docs/en/reference-manual/MKW41Z512RM.pdf
4. By the way , the Peripheral configuration for KW41 is planned :

Hope it helps
Have a great day,
TIC
