@maethaxi Good info!
The Adafruit must be an older design, as the I2C pins are not in the Grove signal order and would require cutting the end from a Grove cable and crossing wires and soldering!
The Sparkfun unit is 'micro-grove' JST 1.0mm but wired correctly for grove. You would need a JST 2.0 (Grove) to JST 1.0 (qwiic) adapter cable. Mine is homemade but opens up another world of sensors to my faithful M5Stack equipment!
