Unit AMeter is a current meter that can monitor current in real-time. It uses a 16-bit ADC digital-to-analog converter ADS1115 internally and communicates via I2C (0X48). To ensure measurement accuracy, it has a built-in DC-DC isolated power supply, and the I2C interface is electrically isolated using a low-power isolator CA-IS3020S to prevent noise and surges on the data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuits. Each unit is… (M5Stack U086)
