The RPi-ADS1115-ADC module is a precision analog-to-digital converter (ADC). The ADS1115 is a chip that can provide 16-bit sampling accuracy, using an ultra-smallData is transmitted through an I2C-compatible serial interface, with 4 I2C addresses to choose from, and only 3.3V is required for the working power supply. Its main function is to detect analog signals and convert them into digital signals.ou can connect the analog signal joystick or other analog sensors such as NTC, temperature, dust sensor and other devices to for the Raspberry Pi through this RPi-ADS1115-ADC module, through the Raspberry PiRead the analog signal collected by the deviceAnalog input voltage: VDD, GNDProgrammable data rate: 8sps to 860spsInternal : SupportI2C interface: address selection via pinsNumber of channels: 4 single-ended or 2 differential inputsProgrammable Comparator (): 2/3 ~16Internal NTC: supportcolour: redMaterial: PVCSize: 65x30x18.0mmPackage Contents:1 x ADS1115-ADC ModuleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
