Pololu I²C Isolator with Isolated Power and Connectors, ISO1640, MIE1W0505BGLVH, 5V/3.3V, 200mA
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 has JST SH-style 4-pin connectors that are compatible with Qwiic and Stemma QT. Power specs:
| Input voltage | Output voltage | Max output current |
|---|---|---|
| 4.5 V to 5.5 V | 5 V (default) or 3.3 V (selectable) | 200 mA |
| 3 V to 3.6 V | 3.3 V | 75 mA |
