Ameter Unit is a current meter that can monitor the current in real time. The 16-bit ADS1115 ADC (analog-to-digital) converter can be used to communicate through I2C protocol (By default the I2C address is 0X48 unless manually modified).
In order to ensure the measurement accuracy, there is a built-in DC-DC isolated power supply.
The I2C interface is also electrically isolated through the low-power isolator module CA-IS3020S, This prevents noise and surges on the data bus or other circuits from entering the local ground terminal to interfere or damage sensitive circuits.
The unit has a maximum measurement current of ±4A, and an internal integrated 4A fuse to prevent excessive measurement current from burning out the circuit.
