LEDs
Power-OK Indicators: D13 ~ D18
The LED D13 to D18 are used for indicating on-board Power-OK status.
LED Signal
D13 +5V Power-OK Status
D14 +3.3V Power-OK Status
D15 +1.2V Power-OK Status
D16 +2.5V Power-OK Status
D17 +1.8V Power-OK Status
D18 All On-board +3.3V, +2.5V, and +1.8V Power-OK Status
USB General Purpose or Status Indicators: D21 ~ D24
The LED D21, D22, D23, and D24 are connected to the on-board USB device controller’s
pin PC0, PC1, PC2, and PA0, respectively. Therefore, they can be used as general
purpose indicators or status indicators, and are controllable via EZ-USB FX2 program.
Note that a logic 0 (low) turns the LED on and a logic 1 (high) turns the LED off.

FPGA General Purpose Indicators: D1, D2, and D30 ~ D32
The LED D1, D2, and D30 to D32 are connected to the dedicated on-board FPGA’s I/O
pins. They can be used as general purpose indicators and are software controllable via
internal FPGA register. Note that a logic 0 (low) turns the LED on and a logic 1 (high)
turns the LED off.

D31 EP3C16_GPO1
D32 EP3C16_GPO2
FPGA Status Indicators: D25 ~ D27
The LED D25, D26, and D27 are used for indicating the on-board FPGA’s status. Note
that a status signal logic 0 (low) turns the LED on and a logic 1 (high) turns the LED off.
