Overview
The Freescale Freedom development platform is an
evaluation and development tool ideal for rapid
prototyping of microcontroller-based applications. The
hardware design is form-factor compatible with popular
third-party hardware designed to work with Arduino™
and Arduino-compatible boards.
The Freescale KL03Z freedom board (FRDM-KL03Z) is
a simple, yet sophisticated design featuring a Kinetis L
Series microcontroller KL03Z, a 3.3 V microcontroller
built on the ARM® Cortex™-M0+ core.
The Kinetis L series is the most scalable portfolio of
low-power, high-robustness, mixed signal 32-bit ARM
Cortex-M0+ MCUs running up to 48 MHz in the
industry. It supports power supply voltage range from
1.71 V to 3.6 V, ambient operating temperature ranges
from –40C to 105C and includes up to 64 KB flash.
The FRDM-KL03Z includes the Freescale open standard
embedded serial and debug adapter known as OpenSDA.
