Can we make safe I2C connection between pixy and nodemcu ?(nodemcu input voltage 3.3v and pixy is 5v?)
Hey, I’m pretty sure Pixy sends 3.3V signals. @edge might know better than I…
I’m not familar with nodemcu, but Pixy uses weak pullups (82K) to 5V for its I2C signals. This is unlikely to cause any issues with 3.3V systems, but you should always check the relevant datasheets for your system.
