There are no boundaries with this module! You decide what inputs, outputs and controls it has. You also design the circuit for what you want the module to do. There are ideas and some circuits designs on the forum, see the DIY section
The photograph above shows the parts included in the kit so your project can fit in the AE format.
The schematic of the DIY module: Attach:DIY-module-schematic.pdf
If you are interested in building your own circuits/modules you should also look at the braedbaord module.
Enjoy your time down the rabbit hole.....
