Board Handling Precautions
To prevent damage due to Electrostatic Discharge (ESD), keep your board in its antistatic bag until you are ready to install it into your system.
When removing it from the bag, hold the board at the edges, and do not touch the components or connectors. Handle the board in an antistatic
environment, and use a grounded workbench for testing and handling of your hardware.
Physical Characteristics
STEP model is available upon request; contact RTD Tech Support for more information.

Connectors and Jumpers
Figure 2: Board Connections
3.3.1 EXTERNAL I/O CONNECTORS
CN4, CN5, CN6 and CN7: USB 3.0 Type A Connectors
CN4, CN5, CN6 and CN7 are USB 3.0 Type A connectors. They support connections at SuperSpeed, HighSpeed, FullSpeed, and LowSpeed.
The Type A connector contains a total of three differential pairs, as well as power and ground. Two of the differential pairs are for SuperSpeed
(TX and RX) and one is for the other speeds.
3.3.2 BUS CONNECTORS
CN1 (Top) & CN2 (Bottom): PCIe Connector
The PCIe connector is the connection to the system CPU. The position and pin assignments are compliant with the PCI/104-Express
Specification. (See PC/104 Specifications on page 17)
The USB25407 is a “Universal” board, and can connect to either a Type 1 or Type 2 PCIe/104 connector.
CN16: PCI Connector (USB25407 only)
The PCI connector is pass-through. The only electrical connections to the board are power and ground. The position and pin assignments are
compliant with the PCI/104-Express Specification. (See PC/104 Specifications on page 17)
CN5: USB Port 2
CN6: USB Port 3
CN7: USB Port 4
