6 FRDM-KL25Z Freedom Development Platform

The NXP 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 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.

6.1 Connecting the FRDM-KL25Z to the board

The FRDM-KL25Z evaluation board was chosen specifically to work with the FRDM-

PF1550EVM 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-PF1550EVM connects to the FRDM-KL25Z using the four dual row Arduino

™

R3 connectors on the bottom of the board.
