Cytron Uno + LoRa module

Hi. I have an LoRa module that I want to connect to the Uno. Do I need to use 5V <-> 3.3V level shifter? Or can I directly connect to it with jumpers?

Hi,

In my experience, I ran a quick test before without level shifter and the module is still working. However this was my case and I don't know about yours. If you want to try without level shifter, try at your own risk!

It is advisable to use logic level shifter, just to be safe.

Thanks bengchet. I'll get the logic level shifter.
