It can provide a broad range of expansion board options. The on-board interfaces include LED, a 3-axis
digital sensor (3D accelerometer), and two capacitive touch pads.
There are many software development tool options available to the user. Choices include Kinetis Design
Studio (KDS), IAR Embedded Workbench, Keil MDK featuring the µVision IDE, and so on.
All of these features combine to give users the Tower needed to rapidly prototype many embedded
designs: a powerful microcontroller built on a very low-power core and SOC platform, easy-access to
I/O with a large ecosystem of compatible hardware, a flexible programming and debug interface, and a
large ecosystem of software development environments.
