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, and provides an isolated 3.3V or 5V voltage, eliminating the need for an external I2C power supply. 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.
