M5Stack Ammeter Unit (ADS1115) FEATHERWING You will need IEEE 802The 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 isolator module CA IS3020S, this prevents noise and surges
