How to supply 5v to Basys3's PMOD?

[Emir Aker]

Hi everyone,

I am using HC-SR04 sensor with my Basys3 Board for a project. Sensor requires 5v source but Basys3 can only supply 3.3V as far as I know. Can Basys3 supply 5V from the PMOD's by using an external 5v source from its J6 pin? Or is there any other way to get 5v from the PMOD?

Thank you

I apologize for the long delay.

There is not a way to make the Basys 3 provide 5V from the Pmod header as that is already a set voltage by the FPGA bank. You might be able to use an external shift register to adjust the output IO signal voltages from 3.3V to 5V and then externally power the HC-SR04 with a separate 5V power supply (making sure that the grounds of the Basys 3 and the external power supply are connected), but there is not a way to do this natively from the Basys 3 itself.

Thanks,
