Digital signal isolator for communication via the Gravity I2C interface. It allows you to isolate the I2C digital signal and provide isolated power to the sensor module. DFRobot DFR0565
Digital signal isolator for communication via the Gravity I2C interface. It allows you to isolate the I2C digital signal and supply isolated power to the sensor module, effectively preventing mutual interference between modules. The module has a built-in 5 V isolation power supply and can directly power the sensor module (without additional power supply) with a maximum current of 150 mA. The set can be used in water quality detection systems to prevent mutual interference between sensors and actuators, e.g. pumps. A user manual is available on the Wiki page.
