GPIO / 1-Wire converter with DS2413 chip

USB port isolator based on the ADUM3160 chip. The device has a rated insulation voltage of 1500V. The isolator is powered from the USB port.

A module that provides galvanically isolated, bidirectional I²C communication and isolated power supply, protecting devices from misconnections and voltage differences. Thanks to the TI ISO1640B device, it supports data transfer up to 1.7 MHz, and the power supply isolation via MPS MIE1W0505BGLVH eliminates ground loops and interference. Pololu 5393

Adafruit 2264

A USB-to-I²C adapter that allows a computer to act as an I²C bus controller, supporting speeds over 1 MHz, clock stretching, and bidirectional communication. The device offers full galvanic isolation between USB and I²C, protecting the computer from damage and interference. With JST SH and goldpin connectors, USB-C support, a virtual serial port, and a Python library, the adapter is a versatile tool for working with I²C devices in both hobbyist and professional projects.
