M5Stack M5 Core, M5StickC, M5StickV

The M5Stack 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.
