Hi there I have a Arduino Nano project with 2 I2C devices. First, a 16x2 display and a compass. The I2C wires from the compass are soldered to the display, from where the wires go to the Nano, via a pull ups on both lines. Unfortunately I only had 10K resistors for the pull ups. I know, the values…

I2C problems with 2 devices

Could it be the high pull up value?

It would cost you less than a dollar to find out.
