Product information "M5Stack voltmeter unit (ADS1115)"

Voltmeter Unit is a voltmeter that can monitor the voltage in real time. The 16-bit ADC (analogue-to-digital converter) ADS1115 is used internally for communication via I2C (0X49).

To ensure measurement accuracy, an isolated DC-DC power supply is installed and the I2C interface is also galvanically isolated by the CA-IS3020S low-power isolator.

This prevents noise and surges on the data bus or other circuits from entering the local earth terminal and interfering with or damaging sensitive circuits. Each device is individually calibrated when it leaves the factory, with an initial accuracy of 0.1%FS, ±1 count, and a maximum measurement voltage of ±36V.

The EEPROM (0x53) is supplied with calibration parameters. Please do not write to the EEPROM, otherwise the calibration data will be overwritten and the measurement results will be inaccurate.
