  @lukasmaximus said in [Solved]Official Grove cables - buckled or unbuckled?: Just a caveat guys, beware that some vendors of the grove cables have the yellow and white wires switched so if you find your units aren't functioning correctly remember to check the cables first. @lukasmaximus Thanks, i will add that to the book.

  @yellowelise Really sorry about that. It's my fault. WEIGHT does not communicate with core through IIC.

  @jpilarski If you want to realize face recognition function with F camera, you just need to change the pin map that is corresponding to F camera.

  @cepics said in Step Motor Module: can I use this motor with this module? It looks like it should work but you would need to adjust the drivers. I don’t have one so I can’t say for certain but it is a 4 wire stepper

  I tested a hub device attached to port A with a few 100cm grove cables and I was able to successfully read the i2c address of the ENV sensor and also others. I tested with the i2c_tester arduino program https://github.com/m5stack/M5Stack/blob/master/examples/Advanced/I2C_Tester/I2C_Tester.ino perhaps its just an isolated incident.
