  • Hello all,

    I recently bought this sensor for my Arduino UNO. I am a beginner with these stuff, so some questions: 1) According to the hookup guide I need some 330ohm resistors for the I2C lines. How do they calculated the exact resistor amount to reduce 5V to 3.3V? I will like some theory here. 2) Do I need these resistors if I am only connecting this sensor in the UNO (I don't have other breakout boards)? or I will burn the breakout without them?

    Thanks

No public wish lists :(
