The ADS1115 16-Bit Precision ADC Module is a high-resolution analog-to-digital converter designed for accurate sensor and analog signal measurement. It provides four single-ended or two differential input channels, supports a wide 2.0V–5.5V supply range, and offers programmable data rates from 8 SPS to 860 SPS. With an integrated PGA, internal voltage reference, oscillator, and I²C interface, it is ideal for Arduino, ESP32, Raspberry Pi, robotics, IoT, and precision data-acquisition projects. PCB colour may be blue or purple and will be supplied randomly; images are for representation only.
