Gravity: I2C Digital Signal Isolator Module

SKU: DFR0565

The Gravity I2C Digital Signal Isolator Module is designed to improve connectivity between devices by utilizing an I2C protocol. It works on a 5V operating voltage and features PH2.0-4P connectors for easy integration. The module includes non-isolation and isolation sides, ensuring secure signal transmission between the controller and the sensor module. With its compact dimensions of 42 * 32mm, the isolator module is highly adaptable for various applications requiring reliable signal isolation and transmission. The pinout details provide clarity on power input and output connections, as well as the I2C SCL and SDA signals. The module's design allows for seamless integration with the main control board's I2C bus and sensor modules, fostering robust and efficient communication. This digital signal isolator is ideal for setups that require precise signal management and isolation, making it a valuable addition to any electronic project.
