5 FRDM-KL25Z Freedom SPI dongle
The NXP Freedom development platform is a set of software and hardware tools
supporting evaluation and development. It is ideal for rapid prototyping of microcontroller-
based applications. The NXP Freedom KL25Z hardware, FRDM-KL25Z, is a simple,
yet sophisticated design featuring a Kinetis L series microcontroller, the industry's first
microcontroller built on the ARM
®
Cortex
™
-M0+ core.

5.1 Connecting the FRDM-KL25Z to the board
The FRDM-KL25Z evaluation board was chosen specifically to work with the FRDM-
HB2000FEVM kit because of its low cost and features. The FRDM-KL25Z board makes
use of the USB, built in LEDs and I/O ports available with NXP’s Kinetis KL2x family of
microcontrollers.
The FRDM-KL25Z connects to a PC through a USB port, which permits the user
to control a DC brushed motor and to drive the evaluation board inputs in order to
operate the motor via the GPIOs and SPI pins. The FRDM-KL25Z also monitors the SPI
registers, thereby facilitating the use of safety and advanced diagnostic functions.
