Chapter 1 – Developer Kit Introduction
Overview
The MTUDK2-ST-Cell Universal Developer Kit supports development with cellular SocketModem, Dragonfly
(including Dragonfly Nano), and mDot devices. Use the developer board to streamline your development efforts
and evaluate your products and applications. Easily plug in your communications device and use the developer kit
for testing, programming and evaluation.
Note: Use this Developer Guide for developing with all SocketModem or Dragonfly models. If developing with
an mDot, use the MultiConnect®mDotTM Developer Guide, which includes device and developer board
information specific to mDots. Go to the mDot Developer Kit page at
http://www.multitech.com/models/94558010LF.
Warning: Do not use an mDot and a Dragonfly or Socketmodem on this board at the same time. Doing to may
damage both devices.
