Change voltage level of Nicla Vision

Arduino Boards
1

Hello, I am using the Arduino Nicla Vision and try to read a speed sensor. I think that the voltage level of my Nicla Vision might be wrong. According to the data sheet the voltage level can be set in software:

Digital Pins voltage level can be forced externally through VDDIO_EXT or internally set to 3.3V or 1.8V with: nicla::enable3V3LDO() and nicla::enable1V8LDO() respectively.

How can this be done with OpenMV?

Thanks!

Hi, you shouldn’t need to do this. The system should be fine for talking to 3.3V sensors. If you need 1.8V you should use level shifters.
