The CJMCU-ADS1115 16-Bit ADC Development Board Module is a high-precision analog-to-digital converter designed to measure analog signals and convert them into digital data for microcontroller-based applications. Built around the ADS1115 integrated circuit from Texas Instruments, this module provides 16-bit resolution, making it suitable for applications requiring accurate sensor measurements and data acquisition. 

The module supports four single-ended analog inputs or two differential inputs and communicates with compatible microcontrollers through the I²C interface. Its integrated programmable gain amplifier (PGA) allows users to configure the input range for measuring different signal levels. With low power consumption and a compact design, it is ideal for Arduino, ESP32, Raspberry Pi, and other compatible development platforms.
