Supports all RS-232 signals.
PROTO1 (J11, J12, J13) Expansion prototype
connector
Expansion headers connecting to 41 I/O pins on the
FPGA. Supplies 3.3V and 5.0V for use by a daughter
card.
PROTO2 (J15, J16, J17) Expansion prototype
connector
Expansion headers connecting to 41 I/O pins on the
FPGA. Supplies 3.3V and 5.0V for use by a daughter
card.
CON3 CompactFlash connector CompactFlash connector for memory expansion.
JH1, JH2 PMC connector Expansion connector for a PCI mezzanine card.
J25 Mictor connector Mictor connector providing access to 27 I/O pins on
the FPGA. Allows debugging Nios II systems using a
First Silicon Solutions (FS2) debug probe.
TP1 – TP8 Test Points Test points providing access to eight FPGA I/O pins.
J24 JTAG connector JTAG connection to the FPGA allowing hardware
configuration using the
Quartus
® II software and software debug using the
Nios II IDE.

controller.
J27 EPCS configuration header Connects to the EPCS serial configuration device for
in-system programming.
Configuration & Reset
U3 MAX Configuration controller Altera MAX EPM7256AE device used to configure
the FPGA from flash memory.
U69 Serial configuration device Altera EPCS64 low-cost serial configuration device to
configure the FPGA.
SW8 CPU Reset button Push-button switch to reboot the Nios II processor
configured in the FPGA.
