ADS1015 12-Bit I2C ADC Module with Programmable Gain Amplifier (PGA)

The ADS1015 is a low-power, high-performance 12-bit Analog-to-Digital Converter (ADC) that allows microcontrollers such as Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and other development boards to read analog signals with greater accuracy and additional input channels.

Unlike many microcontrollers that have limited ADC resolution or no analog inputs at all, the ADS1015 provides four analog input channels (or two differential channels), a programmable gain amplifier (PGA), and a fast I2C interface for simple integration into your projects.

The onboard PGA allows measurement of very small voltage signals without requiring external amplification, making it ideal for sensors, instrumentation, battery monitoring, and precision measurement applications.
