Stratix II Development Board
Expansion Prototype Connector (J26, J27, J28)
Headers J26, J27, and J28 collectively form a standard-footprint,
mechanically-stable connection that can be used (for example) as an
interface to a special-function daughter card.
The expansion prototype connector interface includes:

41 I/O pins for prototyping. All 41 I/O pins connect to user I/O pins
on the Stratix II device. Each signal passes through analog switches
(U27, U28, U29, U30 and U31) to protect the Stratix II device from 5-V
logic levels. These analog switches are permanently enabled. The
output logic-level on the expansion prototype connector pins is 3.3 V.
A buffered, zero-skew copy of the on-board OSC output (from U2).
A buffered, zero-skew copy of the Stratix II device’s phase-locked
loop (PLL)-output (from U60).
A logic-negative, power-on reset signal.
Five regulated 3.3-V power-supply pins (2A total max load for both
expansion prototype connectors).
One regulated 5-V power-supply pin (1A total max load for both
expansion prototype connectors).
Numerous ground connections.
