8. CONNECTOR PINOUTS

This page describes the pinouts of various connectors available with the JETBOX-FLOYD system.

8.1 Input Power Connector

The system provides a barrel connector for main input power. The connector has a 2.5mm center pin and is intended for use with mating connectors with 2.5mm inner diameter and 5.5mm outer diameter. Input voltage = +7V to +24V.

The connections for the power input connector are Tip = +V and Ring = -V.

Connector Part Number: PJ-202BH

Front Panel Exposure: YES

8.2 Serial Port 1 (SER 1)

JETBOX-FLOYD has two Serial Ports of which one of the serial ports, SER 1 has a dedicated connector terminated on J1. The serial port SER 1 is directly accessible on the front panel. The second serial port SER 2 is not directly exposed on the front panel; rather it is accessible on the front panel at EXP 1.

The SER 1 is multiplexed with DIOs with assembly options. The DIOs from the connector J9 on the Floyd carrier card can be routed to SER 1 (J1) connector. The pinouts of SER 1 connector are as shown below:

Connector Part Number: A-DS 09 A/KG-T2S

Front Panel Exposure: YES

8.3 Serial Port 2 (EXP 2)

By default, the serial port 2 SER 2 is terminated at J9. To enhance the functionalities of the Jetbox-Floyd, the SER 2 is made available on the front panel at EXP 2. The pinouts of the SER 2 at EXP 2 are as shown below:

Connector Part Number: 010309-00002201

Front Panel Exposure: YES, on EXP 1

8.4 USB2 Ports 1,2

The Jetbox-Floyd hosts two USB 2.0 ports accessible on a vertically stacked standard USB 2.0 Type A socket that uses standard pinout. The pinouts are as shown below:

Connector Part Number: UB1112C-8FDH-4F

Front Panel Exposure: YES

8.5 USB3 Port

The Jetbox-Floyd hosts one USB 3.0 port accessed via an upright standard USB 3.0 receptacle. The pinouts of the connector are as shown below:

Front Panel Exposure: YES

8.8 Digital I/Os (EXP 2)

The DIOs & the SER 2 on the Floyd carrier board of the Jetbox-Floyd are terminated on the same connector J9. This connector is accessed with a cable and exposed on the front panel. The SER 2 from J9 is terminated at EXP 1 on the front panel & the DIOs from J9 are terminated at EXP 2.

The DIO pinouts terminated at EXP 2 are as shown below:

Connector Part Number/Type: 2x10, 2.54 mm Header

Front Panel Exposure: YES, on EXP 2

8.9 Reset Switch

The Reset switch is used to reset the Jetbox-Floyd system. When the Reset switch is pressed, the system goes into Reset mode until the switch is released. When the switch is released, the system comes out of Reset mode & system boots to the operating system.

8.10 Recovery Switch

The Recovery switch is used to operate the system in Recovery mode. The recovery mode is used by the system to update its Board Support Package (BSP).

The usage of the Recovery switch has been detailed in Section 14. REPORGRAMMING THE EMBEDDED LINUX IMAGE.

8.11 SMA Antenna Connectors 1, 2

Jetbox-Floyd system provides 2 SMA connectors to connect external antennas. These connectors can be used when a WiFi or LTE module is used to extend the connectivity on the M.2 or mPCIe expansion.

The WiFi/LTE modules can be wired to the SMA connector internally with U.F.L to SMA cables.

8.12 EXP 2: Controller Area Network (CAN) (Optional)

The CAN interface is optionally accessible from the front panel. The pinouts of the EXP 2 for CAN interface are as shown below:

Connector Part Number/Type: 010309-00002201

Front Panel Exposure: NO, optionally available on EXP 2

8.13 EXP 1: PoE Power Input (Optional)

The PoE Power Input connector is optionally accessible from the front panel. The pinouts of the EXP 2 for PoE Power Input are as shown below:

Connector Part Number/Type: 010309-00002201

Front Panel Exposure: NO, optionally available on EXP 2

NOTE: The subsequent connectors have been referenced with the reference designators on the Floyd base board. Refer Floyd User Manual for more details.

8.14 J19: PCIe M.2 SSD Socket (M-Key, 2280 Size)

The Floyd carrier board is equipped with an M.2 PCIe SSD M-keyed connector for 2280 sized modules for storage applications.

The PCIe link routing from the Jetson module to the M.2 socket varies according to the Jetbox-Floyd model.

JB-FLD-NAO/XNX-01: The PCIe x4 link from the Jetson module is routed to a switch which provies 3 PCIe x1 links for the M.2 socket, PCIe minicard socket, and 2nd Ethernet port.

JB-FLD-NAO/XNX-02The x4 PCIe link is directly connected to the M.2 socket for maximum bandwidth. The minicard and 2nd Ethernet port are not present. With the Jetson Xavier NX module installed, an additional PCIe x1 lane interface can be mapped from the NX to the second Ethernet.

NOTE: Contact Diamond Systems Corp for custom build options.

The M.2 socket follows standard pinouts & the pinouts of the connector J19 are as shown below:
