How to turn on LED with PMOD on FPGA
Assuming you can control each PMOD signal independently, I would build this circuit:







simulate this circuit &ndash; Schematic created using CircuitLab

This will allow you to power the LED with about 15 mA; my understanding is the max output from the PMOD signals are 8 mA. When the PMOD GPIO is 1, the LED is on, and off otherwise.
