4 Electrical Interfaces
This section provides a detailed description of the various P330 electrical interfaces. A standard P330
has the following connections:
 One antenna port
 Communications for Low Speed Serial, USB 2.0, Ethernet, CAN, SPI
 Connections for up to 15 GPIO pins
 Connections for power (5 to 48V), Ground, and Chassis Ground
There are also eight indicator LEDs, six on the board and two on the RJ45 jack.
The physical interface to Communications, GPIO, and Power are through a mix of connectors (see
Figure 4-1) including the following:
 Three mezzanine connectors
 One locking connector
 One Ethernet RJ45 connector
 Two USB connectors (one power-only, one for data-only)
 Two 0.1” DIP header, (one for the user and one for Factory checkout)
This arrangement provides the user with a maximum of flexibility for evaluating the technology and
demonstrating product proofs of concept. This flexibility of course comes with a monetary cost and
at some point in time the user will need to consider a stripped down implementation which provides
the required performance at a fraction of the cost. For further details on reducing the cost, contact
