Hi all, has anyone successfully used the Si570 with a Teensy 4, it should be straightforward but looking around I do not see any projects where it has been used with Teensy 4, only Arduino's. I would assume as the Teensy and Si570 are both 3.3v there would be no need of pull up resistors on the i2c lines. I note on the 5v devices they tend to use 4.7k resistors.
