3.0 Hardware Description
3.3 Nano Interface Card
The Nano Interface Card provides a convenient adapter to work with existing MHX development boards and
MHX based designs. Using the Interface Card user’s can quickly condition existing MHX interface signals to
work with the Nano Series. The Interface card converts 5V logic to 3.3V logic and routes the signals to MHX
pin-out designations.
The Interface Card can also be used to retrofit Nano Series Modems into existing designs, as well as provide
a mounting mechanism for new designs. The mechanical interface for the electrical signals is a 40-pin
connector (see image above).
Being ready to deploy, the Nano Series with Interface card can minimize the development cycle time
associated with building-out from the Nano OEM module alone.
