M5Stack AMeter Unit Ammeter ADS1115

The M5Stack Ameter Unit is a current meter that can measure up to + -4A. The module has a built-in 4A fuse to prevent a too high measuring current from burning out the circuit. To ensure measurement accuracy, an isolated DC-DC power supply is built in. The 16-bit ADS1115 analog-digital converter can be used for communication via the I2C protocol (the standard I2C address is 0X48 unless manually changed). The I2C interface is also electrically isolated by the CA-IS3020S low-power isolation module. Each device is factory calibrated with an initial accuracy of 0.1% FS, ±1 count, and a resolution of 0.3 mA.

ATTENTION: Calibration data and parameters are stored on the EEPROM memory. Make sure you do not overwrite the EEPROM to prevent false measurements
