1. Introduction

This guide describes the hardware for the FRDM-
K32L3A6 Freedom Development Board. The FRDM-
K32L3A6 freedom development board is a small, low-
power, and cost-effective evaluation and development
board for application prototyping and demonstration of the
K32 L3 family of devices. These evaluation boards offer
easy-to-use mass-storage-device mode flash programmer,
a virtual serial port, and standard programming and run-
control capabilities.
The K32L3A6 is an ultra-low power solution for
embedded products requiring extended battery life.
