M5Stack Voltmeter Unit Voltage Meter ADS1115
The M5Stack Voltmeter Unit is a voltage meter that can measure up to ±36V. To ensure measurement accuracy, an isolated CA-IS3020S 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 calibrated at the factory with an initial accuracy of 0.1%FS, ±1 count
WARNING: Calibration data and parameters are stored on the EEPROM memory. Make sure you do not overwrite the EEPROM to prevent incorrect readings.
