FRDM-KL25Z Freedom Development Platform
The Freescale Freedom development platform is a set of software and hardware tools for evaluation and development. It is ideal for rapid
prototyping of microcontroller-based applications. The Freescale 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.
4.1 Connecting FRDM-KL25Z to the Board
The FRDM-17C724-EVB kit may be used with many of the Freedom platform evaluation boards featuring Kinetis processors. The
FRDM-KL25Z evaluation board has been chosen specifically to work with the FRDM-17C724-EVB 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 Freescale’s Kinetis KL2x family of
microcontrollers. The main functions provided by the FRDM-KL25Z are to allow control of a stepper motor using a PC computer over USB,
and to drive the necessary inputs on the FRDM-17C724-EVB evaluation kit to operate the motor.
The FRDM-17C724-EVB is connected to the FRDM-KL25Z using four dual row headers. The connections are as follows:
