Features Internal PGA supports sampling precision 16-bit, I2C port through pin selection addresses channel count. 4 single-ended or 2 differential inputs, programmable comparator 2/3~16. Power supply 3.3V, analogue input voltage VDD, GND programmable data speed 8sps to 860sps. The ADS1115-ADC is a precise analog-to-digital converter (ADC). The ADS1115 is a chip that can provide 16-bit sampling precision using an ultra-small MSOP-10 case. Features: Internal NPT support data through I2C compatible series port to transfer, there is 4-channel I2C address that can be selected, working power supply only requires 3.3V; Its main function is the analog detection signal and convert it into a digital signal. You can connect analogue sensors, such as joystick, NTC, temperature, dust sensor, for Raspberry Pi converter, and read the collected signal. Specifications: Compatibility: For Raspberry Pi 3/2/B+ Size: 6.5 x 3 cm. Weight: 15g (approx.) Package includes: 1 x ADC module. Package List
