Starter Kit Demo Board: Versatile platform for function expansion and module comparison

The demo board is the basic platform of the Starter Kit and provides several functional units. These units include power supply, USB interface, and several input and output elements, such as push buttons, DIP switches, potentiometer, and LEDs. In addition all pads of the attached radio module can be accessed via pin connectors.

Connection between the radio module and the demo board is established via a module-specific adapter board. The radio module is soldered on the adapter board which is attached to the demo board through pin connectors. The adapter board also has a SMA jack connected to the RF output of the radio module, which can be used to connect an external antenna (or RF measuring and test equipment).

By using the adapter boards all WiMOD radio modules can be attached to the same demo board. In that way an easy comparison between the modules is achieved to determine which one is the best for a target product. The adapter boards including the appropriate radio modules can be ordered separately to expand the Starter Kit.
