Maybe because\none of them is grounded, maybe because you have some fancy performance\nmonitors, maybe you want to reduce the noise. Whatever it is, you can add full\ngalvanic insulation between the two ends of the I2C bus by using the ISO1540\nbi-directional I2C insulator. The chip we use, the TI ISO1540, is fully bi-\ndirectional, supports clock speeds of up to 1 MHz, supports clock stretching,\nworks with 3 to 5 V DC current or logic (of course separated sides) and has\n2500 V-RMS insulation. It is easy to use - you will receive\npower\/ground\/clock\/data separation pads for each side as well as a matching\nSTEMMA QT connector. Unlike our other QT boards, the sides are naturally\nelectrically insulated, which means that each half needs to be powered! Make\nsure the green LED lights up. Now send the data via I2C and you're ready to\ngo. We have 10K pull-outs on each side from the I2C pin to the corresponding\nVCC.
