I start learning about FPGA some days ago but I have a problem with the "PMod". I want to simple turn an Arduino on/off, direct from the VIN (this support 3.3V) using a Basys 3, using the PMod connector. For simplicity I replace the Arduino for one led, for test propose.
When I connect the Arduino into the 3.3V + GND on FPGA the Arduino (and the led) work very well, as expected. However, when change the wire from “3.3V” to another port (K17 for instance) this fail.
The light of the led is weak and the Arduino not turn on. I not have a multimeter to see what is the voltage or more information about what is happening.
I think the pin (JC1, JC2…) is not working on 3.3V, however this is set to use LVCMOS33.
How I can fix that have another way to achieve that?
