16-bit 4 channel ADC module

Sometimes the Arduino Uno or ESP Wemos analog pins are just not enough. This unit allows you to add 4 more analog inputs to your microcontroller using the easy to use I2C interface of your microcontroller.

Even better, it gives you higher precision, as an example, than the Arduino analog pins. This ADC module also comes with a programmable gain amplifier to boost your input. Uses the ADS115 IC

ADC module Features:
For microcontrollers without an analog-to-digital converter, or when you want a higher-precision ADC. This ADS1115 provides 16-bit precision at 3300 samples second over I2C.
The chip can be configured as 4 single-ended input channels or two differential channels.
As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range.
This ADC can run from 2V to 5V power/logic, measure a large range of signals and easy to use.
It is a great general purpose 16 bit converter.
The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet.
Interfacing is done via I2C.
The address can be changed to one of four options, so you can have up to 4 ADS1115's connected on a single 2-wire I2C bus for 16 single ended inputs.
