I am having trouble getting Grove MCP9600 to work with a Arduino Nano 33 IOT. It works with my Seeeduino V4.2. I first tried seeed support email and after some back and forth, they told me to post it in the forum. Any suggestions?
What’s the problem? Maybe if you describe it in detail, I can help you better.
Serial monitor reads out mostly 0. Sometimes 1 or 1.06. Again it works reads properly when connected to the seeduino.

OK I finally figured it out on my own. To work with the Arduino Nano 33 IOT, I had to change the address jumper on the Seeed MCP9600 board. The default was 0x60. I broke the trace for the low side address pad and solder bridge the center position pad to the high side address pad. Update code to use 0x67 address. add following to Setup section of code.
sensor.set_iic_addr(0x67);
