ADS1115 16-Bit ADC Module

Description

The 4-channel 16-bit ADS1115 ADC Module is a high-precision analog-to-digital conversion solution based on the TI ADS1115IDGSR chip. This module provides four 16-bit precision analog input channels, supports both 3.3V and 5V operation, and features a hardware-configurable I2C address. The module also integrates an NTC temperature measurement interface, enabling multi-channel signal acquisition and temperature monitoring.


Features

  • Support 3.3V to 5.0V Wide Supply Voltage, 3.3V I2C digital level signal, optimized for Raspberry Pi.
  • Ocean I2C Interface, plug and play, 22AWG environmentally friendly high temperature resistant silicone wire, JST 4-Pin to DuPont female single head, wire length 210mm.
  • On-board I2C address selection switch, supports cascade of two ADC modules.
  • Color coded 3pin headers, plug and play with Arduino analog sensors.
  • Comes with development resources and manual (examples for Raspberry Pi/Arduino)
