ITEM NAME:1pc 3.3V ADS1115 ADC Module for Raspberry Pi 3/2/B Analog to Digital Converter Product Description Description: Feature: - The RPi-ADS1115-ADC module is a precision analog-to-digital converter (ADC). The ADS1115 is a chip that provides 16-bit sampling accuracy in an ultra-small MSOP-10 package. - Data is transmitted via an I2C-compatible serial interface. It has 4 I2C addresses to choose from and only 3.3V for working power. Its main function is to detect analog signals and convert them into digital signals. - You can use the analog signal's joystick or other analog sensors such as NTC, temperature, dust sensor, etc. to access the Raspberry Pi through this RPi-ADS1115-ADC module, and capture the analog signal through the Raspberry Pi reading device. Specifications: Power supply: 3.3V Analog input voltage: VDD, GND Programmable data rate: 8sps to 860sps Internal PGA: Support Sampling accuracy: 16 bits I2c interface: select address by pin Number of channels: 4 single-ended or 2 differential inputs Programmable Comparator (PGA): 2/3 ~ 16 Internal NTC: Support Size: 65*30*18mm/2.56*1.18*0.79 Weight: 16g Notes: Please allow 1-3mm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding.
