The M5Stack AMeter Unit is an ammeter module designed for the M5Stack sets. It can measure direct current in the range from 0 to 4 A with a resolution of approx. 0.15 mA. It is based on a 16-bit ADC converter, which communicates with the evaluation kit via the I2C interface (Grove connector). The module has a built-in isolated power circuit, and the I2C interface is also galvanically isolated through the CA-IS3020S low-power isolator, which prevents noise and surges from penetrating the data bus. The ammeter will be used in projects where accurate current measurement is required. Full documentation is available on the product page.
