New products: Isolated USB-to-I²C Adapters

We’re excited to introduce our new isolated USB-to-I²C adapters! These boards make it easy to control your I²C device from your PC or other USB host, giving your applications access to a world of sensors and actuators or simplifying evaluation and troubleshooting of I²C hardware. Two versions are available, one that requires VCC to be supplied separately to the I²C side and one that can deliver 5V or 3.3V power to your I²C bus from your USB port while still maintaining electrical isolation.

Both adapters offer full galvanic isolation to protect your PC from your experimental circuits and to avoid subtle common-ground problems.

The firmware is open source, so you can customize them, and the galvanic isolation building blocks used in these adapters are available separately in smaller modules if you want to implement your own isolated systems.
