Exactly. This is my first try. I need a way to turn on/off one external device (in this case a Arduino, but I test with one LED) using the FPGA, so no matter what PIN is, only need a 3.3V. When I saw the PMod I thought that all PINs are 3.3V output. In my mind, probably wrong, I can take any one (JC1/K17 of example) to connect into the VIN of the Arduino. But in reality this is under 3.3V, so I can't power up. When I tested it with a LED the light weaker than the JC6. So probaby the JC1 voltage is less than 3.3V.
Hi, 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
