FX2 Breadboard Reference Manual 1300 Henley Court Pullman, WA 99163 Overview The Digilent FX2 Breadboard FX2BB offers a ready-made solution for prototyping breadboarded or wire wrapped circuits as accessories to Digilent system boards. The FX2BB provides connectors suitable for direct connection of various Digilent system boards as well as Digilent peripheral modules Pmods . Features include: • Two 630 tie point breadboards separated by 100 tie point bus strip solderless breadboard version • 32x65 hole wire-wrap area wire-wrap version • Four 6-pin male header • Four 6-pin female header • FX2 connector • Prototype/wire-wrap connections on every signal • Two power buses and one ground plane. The FX2 Breadboard. 1 Functional Description Power Connections The FX2BB provides two power busses and a ground bus. The two power busses are labeled VU and VCC. These two busses are made available at each connector position on the board. There is also a ground plane that connects the ground pins from all connectors together. The usual Digilent convention is to power the VCC bus at 3.3V and the VU bus at 5.0V. However depending on the system board connected and the power supply used, other voltages may be present. Observe caution before using any voltage other than 3.3V on the VCC bus. Most Digilent system boards will be damaged if the voltage on the VCC bus is greater than 3.3V.

Alternatively, the power busses can be powered from the FX2 connector or any of the Pmod connectors. When configuring power jumpers and powering the board, it is important that each power supply bus be powered from a single power source. Damage can occur if the same bus is powered by more than one source. Hirose 100-pin FX2 Connector FX2 connector J11 is provided on one side of the board for connection to Digilent system boards like the Nexys that contain an FX2 style connector. The Digilent FX2 connector signal convention provides for forty general-purpose I/O signals, three clock signals, JTAG signals, and power busses. The forty general-purpose I/O signals from the FX2 connector are brought out to connector J12. These signals are labeled IO1-IO40. See Table 1 for a description of the relationship between FX2 connector pins and signal names on J12. The remaining signals from the FX2 connector are brought out to connector J13.
