    The KwikStik development tool is an ultra low-cost, all-in-one development tool for evaluating, developing and debugging Kinetis MCUs. It features the K40X256VLQ100 (144LQFP) MCU with USB, Touch Sensing and Segment LCD functionality. The KwikStik development tool can be used standalone or integrated with the NXP Tower System. The on-board Segger™ J-Link™ debug interface allows the user to evaluate the features of the on-board Kinetis K40 MCU or to develop, debug and program their own target hardware based on any Kinetis MCU.

    The KwikStik development tool comes pre-flashed with demonstration software to exercise a small portion of the capabilities of the Kinetis K40X256 device and the KwikStik hardware.


    • Stand-Alone: Evaluate the on-board KinetisK40X256 (144LQFP) MCU using the touchsensing interface, 306 segment LCD display, audio, infra-red and SD card interfaces.
    • With the NXP Tower System: Offers multiple system expansion options from NXP and third-party peripheral modules, including sensing, Wi-Fi® and industrialconnectivity.
    • As a J-Link Debugger: Interface direct tothe user’s target hardware for evaluating, developing and debugging with any external Kinetis MCU.


    Key Applications: GPS receivers, Blood glucose meters, Bike computers, Currency counters.
