ADS1115 16-Bit I²C Analog-to-Digital Converter (ADC) Module – 4-Channel High-Precision Input

The ADS1115 16-Bit I²C ADC Module is a high-precision analog-to-digital converter based on the Texas Instruments ADS1115 IC. It allows microcontrollers and single-board computers without accurate analog inputs to read analog voltage signals with excellent resolution and stability.

With 16-bit resolution, a programmable gain amplifier (PGA), and a simple I²C interface, the ADS1115 is ideal for sensor measurement, battery monitoring, and precision electronics projects.

Commonly used with Arduino, ESP32, ESP8266, and Raspberry Pi platforms.
