Configuration and Setup Elements
J5
On-Board (Embedded) USB-
Blaster II
Mini Type-B USB connector for program‐
ming and debugging the FPGA.
J7
10-pin header
Optional JTAG direct via 10-pin header for
external download cables.
SW2
DIP configuration and user
switch
SW2 includes switches to control boot
images and JTAG bypass.
S6
MAX10 nCONFIG push
button
Toggling this button causes the FPGA to
reconfigure from on-die Configuration
Flash Memory (CFM).
S7
FPGA register push button
Toggling this button resets all registers in
the FPGA.
J11
Jumper for board power option Default connection is Pins 2 and 3 position,
which uses USB power supply. If needed,
change jumper position to Pins 1 and 2 for
DC adapter power supply solution.
Status Elements
