5. FUNCTIONAL OVERVIEW
The following section provides functional details of the key sub-systems implemented on the Floyd carrier board.
Power Supply Specifications
The Floyd carrier board accepts a wide input voltage range of +7V to +24V. Maximum power consumption
with either Nano or NX module installed and all peripherals operating is 35W. The maximum allowable
reflected ripple, measured at the voltage input connector is 50 mV p-p. The input power is provided via a
barrel jack with 5.5mm OD / 2.5mm ID dimensions (tip positive).
Camera Serial Interface (CSI)
The Jetson Nano module connector implements 12x CSI lanes supporting dual- and quad-lane cameras.
The carrier board supports three cameras which are interfaced through 30-pin micro-coax connectors. Each
connector supports I
2
C and control signals to enable users directly interface the camera to the carrier board.
As of this manual revision the following cameras are tested and qualified to run on Floyd with both Nano and
NX modules, and their drivers are integrated into the Diamond Systems BSP for Floyd. Although not listed
or tested, many other cameras designed for Jetson Nano / NX modules should also be compatible with
Floyd. For more information please contact Diamond technical support or visit

Controller Area Network (CAN)
The carrier board is equipped with a CAN interface. The interface is implemented either with a non-isolated
transceiver
PCA82C251T/YM,118
(standard) or an isolated transceiver
ADM3053BRWZ
(optional, contact
Diamond Systems Sales for further information). The CAN feature is available only with the NX module
installed; the Nano module does not include an integrated CAN controller.
Digital
I/O
Floyd integrates a TCA9538 I
2
C GPIO expander IC that implements eight General Purpose Input/output
(GPIO) lines with 3.3V logic level drive and 5V tolerant inputs. Each GPIO line be configured individually for
input or output. 10K pull-up/down resistors are provided on board and are jumper-selected.
The GPIO is available on a 2 x 10 2mm pin header combined with the second serial port.
Display
Floyd supports two HDMI 2.0 a/b video output options:
1x With audio
1x Without audio
Both video outputs terminate on a dual-port vertically stacked HDMI connector.
The Nano module natively supports 1x HDMI and 1x DisplayPort. Floyd uses a bridge chip to convert the
DP port to HDMI.
