SparkFun Qwiic 12 Bit ADC ‐ 4 Channel (ADS1015)

   A lot of the time you just need to add more analog inputs to solve a problem. It happens. The SparkFun Qwiic 12 Bit ADC can provide four channels of I2C controlled ADC input to your Qwiic enabled project. These channels can be used as single-ended inputs, or in pairs for differential inputs. What makes this even more powerful is that it has a programmable gain amplifier that lets you "zoom in" on a very small change in analog voltage (but will still effect your input range and resolution). Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.
