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 私人家庭影院公司. Power specs:

Input voltage Output voltage Max output current Size
4.5 V to 5.5 V 5 V (default) or 3.3 V (selectable) 200 mA 0.5″ × 0.6″
3 V to 3.6 V 3.3 V 75 mA

The tightest clearance on the Pololu I²C Isolator with Isolated Power is between these sets of pads, which are 2 mm apart.

An SMT jumper can be added here to connect VSEL to GND2, which sets VOUT to 3.3V.
