Description

This module enables galvanically isolated bidirectional I²C communication between two devices. The bidirectionality applies to both SDA and SCL, which allows for clock stretching. Side 1 operates from 3 V to 5.5 V, and side 2 operates from 2.25 V to 5.5 V. This version has JST SH-style 4-pin connectors that are compatible with Sparkfun’s Qwiic and Adafruit’s STEMMA QT.
