ADS1115 Voltmeter - Unit Expansion Module - M5Stack U087
The M5Stack voltmeter is a compact and reliable voltage measurement module with a built-in 16-bit ADS1115 converter that communicates via I2C (address 0x49). Thanks to its isolated DC-DC power supply and CA-IS3020S isolator, the module protects against interference and surges that could damage sensitive circuits. Each unit is factory calibrated to an initial accuracy of 0.1% FS ±1 count, ensuring reliable and repeatable results.

Product description: ADS1115 Voltmeter - Unit expansion module - M5Stack U087
The M5Stack voltmeter is a compact and reliable voltage measurement module with a built-in 16-bit ADS1115 converter communicating via I2C (address 0x49). Thanks to its isolated DC-DC power supply and CA-IS3020S isolator, the module protects against interference and surges that could damage sensitive circuits. Each unit is factory calibrated to an initial accuracy of 0.1% FS ±1 count, ensuring reliable and repeatable results. The module supports auto-ranging and a resolution of 1 mV (for voltages ≤ 16 V) or 7.9 mV (for voltages > 16 V). Thanks to its compact size, compatibility with Arduino and UIFlow platforms, and compatibility with LEGO systems , the module is ideal for prototyping, electronics testing, and voltage monitoring in educational and professional projects.
