This module enables galvanically isolated bidirectional I²C communication between two devices while supplying regulated, isolated power to the target. The bidirectionality applies to both SDA and SCL, which allows for clock stretching. The output voltage is set to 5 V out by default and can be changed to 3.3 V through a selection pin. This version does NOT have connectors. Power specs:
