16 P330 Data Sheet / User Guide
DRAFT
The P330 requires less than a Watt of power from a DC supply that provides any voltage between 5.5
and 48 volts. This power can be provided through Time Domain’s standard external power supply, a
battery, or a user-supplied power source. Indicator lights provide operating status information.
The processor monitors and controls the DW1000, initiates range requests, controls the flow of data
to and from the DW1000, operates the network, computes locations and handles the interface with the
host/user.
The DW1000 is a full UWB transceiver. It transmits and receives packets, sends data, initiates Two
Way Time of Flight Range measurements and reports the range measurements as well as several
statistics related to the measurement.
The user can interface to the P330 through Ethernet, USB, SPI, Serial, or CAN. Ten GPIO pins are
available. If the SPI interface is not used, then these pins can be reassigned yielding an additional
five GPIOs for a total of 15.
In addition, the user can request that the P330 report the board temperature.
A variety of means have been provided to physically interface to the P330. These means include two
USB connectors, an Ethernet RJ45 connector, a locking connector, and three mezzanine connectors.
See Section 4 for details. The mezzanine connectors are suitable for mating directly with a customer-
provided board. Mating mezzanine connectors can be ordered with a variety of mated heights,
thereby allowing the user to mount low profile devices on their carrier board underneath the P330.
See Section 5 for details.
