FEZ Medusa is an Arduino-compatible plus gadgeteering-compatible mainboard. Being Arduino-compatible, allows FEZ Medusa to be easily programmed using the Arduino IDE, which runs on Windows, Linux and Mac. A user will only need to plug in the needed modules to the compatible sockets and then include that module’s driver in the IDE and the module is ready to be used. No datasheets to open, no schematics to read. But what about advanced users who are interested in tweaking and modifying the hardware or the software? Since FEZ Medusa is open source, where the hardware and the software are provided free of charge, even for commercial use, advanced users can still dig into the driver’s sources and read the schematics to tweak or completely modify the software and hardware to fit their needs.
The FEZ Medusa Shield-3D is a perfect match for the Arduino DUE, the Arduino Mega and the Arduino Mega ADK. Having the Arduino Mega ADK as an option allows for the building of flexible Android accessories by making the gadgeteering sensor and control modules acessible to the Android's Accesory Development Kit (ADK).
Important note: When using a 5V Arduino, like the Arduino Mega, extra caution should be taken to select modules that can be used safely with 5V micros. This is not a concern when using a 3.3V micro, like the Arduino DUE.
