M5Stack Voltmeter Unit ADS1115

The M5Stack Voltmeter Unit is a voltage measuring device capable of measuring up to ±36V. To ensure measurement accuracy, it features an isolated CA-IS3020S DC-DC power supply. The 16-bit ADS1115 analog-to-digital converter can be used for communication via the I2C protocol (the default I2C address is 0x48 unless manually changed). The I2C interface is also 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.

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