M5Stack Ammeter ADS1115

The M5Stack Ameter Unit is a current measuring device capable of measuring up to ±4A. The module features a built-in 4A fuse to prevent excessive measurement current from burning out the circuit. To ensure measurement accuracy, an isolated DC-DC power supply is integrated. The 16-bit ADS1115 Analog-to-Digital Converter can be used for communication via the I2C protocol (the default I2C address is 0x48 unless changed manually). Additionally, the I2C interface is electrically isolated by the Low Power Isolation Module CA-IS3020S. Each device is factory calibrated with an initial accuracy of 0.1% FS, ±1 count, and a resolution of 0.3 mA.

Warning: Calibration data and parameters are stored in the EEPROM memory. Ensure that you do not overwrite the EEPROM to prevent incorrect measurements.
