Hello, I am hoping to get clarification using the Sparkfun redboard one. I have a weather kit: direction vane, precip bucket, wind speed interfacing to a weather shield DEV-13956. Do I set the Redboard plus to 3.3v or 5v ? Doesn't seem to address this anywhere. My shield uses 3.3v sensors , I am as…

What did Sparkfun say about this ?

There is a bit of conflicting information. Their forum did not have a lot of traffic with useful info. My project if not obvious is to interface the sensors for wind and rain to the redboard. The shield has other sensors on it, I2C from what I gathered. I think will set the board to 3.3v and load te…
