Maximum output voltage on a LoPy4

[Anders H]

Hi,

I wanted to know the maximum output voltage you could get from the LoPy4 with an expansion board 3.1(some sensors might need 6-7V of output is why i am asking). Could i, if its too small, bypass the voltage regulator?

@Anders-H Interfacing things with different voltages is very common in microcontroller projects and there are many tutorials in the internet.
Just google "voltage divider" for higher voltages at input pins and "output driver" for higher voltages at output pins.

@robert-hh
Is there a tutorial for this? Or anywhere i can read about it? Im new so im not quite sure how to do this. Is it possible with, for instance, a battery?

@Anders-H The maximum output voltage is 3.3V. Bypassing the regulator will damage the device. If you need higher output voltages, you have to set up your own circuitry for doing so. For digital signals, a level shifter might work, For analog signals you will need active amplifiers.
