Question EFB-REV1 - IO pins

[Victor_1990]

Hello Everyone,

Am getting started with a EFB-REV1 and I am trying to understand if the GPIOs are 5V or 3.3V tolerant.
I need to know if I can connect it to a 5V sensor.

Thank you.

Hello victor

Any GPIO pins on any hardware are 3.3V data level

now are you asking if you can supply 5V power to the sensor from EFB-REV1 ?
if yes then on the back of the EFB-REV1 you have power supply pins which are 3.3V(8). You can use those pins to supply power to your sensor but remember it is just 3.3V power supply not 5V.

Regards
