Optically Isolated Bidirectional I2C Shield For Arduino

https://www.electronics-lab.com/project/optically-isolated-bidirectional-i2c-shield-for-arduino/

Optically isolator Arduino Shield has been designed to provide optically isolated I2C communication between Arduino and any other device or sensors that works with I2C protocols. I have used the ISO1540 Low-Power Bidirectional I2C Isolator IC from Texas Instruments to build this project, and the device is compatible with I2C interfaces. These devices have logic […]
