Cabling; Table 9: User I/O Connector Pinout And Pin Orientation - VersaLogic Blackbird VL-EPU4562 Hardware Reference Manual

The following table provides the pinout of the user I/O connector.

Table 9: User I/O Connector Pinout and Pin Orientation

Notes:
1. This is the +5V VBUS power for USB Port 1 and 2.
2. This is the +5V VBUS power for USB Port 3 and 4.
3. This 3.3 V power goes off in sleep modes. The SPKR# uses this power as
should the PLED# (there is no requirement for PLED# to use this power, but the
VL-CBR-4005B paddleboard does).
4. This 3.3 V power can be turned on or off similar to the 3.3V power to the Mini
Card via the FPGA (can go off in sleep modes or always stay on; by default it
goes off in sleep modes). It is used for the 10 kΩ pullup resistor power on the 8x
GPIOs and usually for the 2x Ethernet LEDs, however, the Ethernet LEDs can
be powered by a 3.3 V power source.

Cabling

An adapter cable, part number VL-CBR-4005A, is available for connecting the CBR-4005B
paddleboard to the VL-EPU-4562/4462. This is a 12-inch, Pico-Clasp 40-pin to 40-pin cable.
If your application requires a custom cable, the following information will be useful:
