About logic level converter I always listen to this guy - "An ounce of prevention is better than a pound of Cure": Benjamin Franklin. | |

| Apr 26, 2019 at 14:18 | comment | added | pisar | I followed my friend's instruction who told me "Never use 5V in PI" even though tutorial about i2c lcd said 5V. I just thought that 3V3 will be safer. What I'm gonna do is connect lcd to 5V. The question is should I connect DHT to 5V as well? In datasheet is 3.5～5.5V DC so 5V seems proper. Am I right? Can I connect lcd directly to 5V RPI output or should I use logic converter? | |
