Qwiic 12-Bit ADC Hookup Guide
An analog to digital converter (ADC) is very useful tool for converting an analog voltage to a digital signal that can be read by a microcontroller. The ability to converting from analog to digital interfaces allows users to use electronics to interface to interact with the physical world.
The SparkFun Qwiic (12-bit) ADC provides four channels of I2C controlled ADC input to your Qwiic enabled project. These four channels can be used as single-ended inputs, or in pairs for differential inputs. The ADS1015 uses its own internal voltage reference for measurements, but the ground and 3.3V power are also available on the pin outs for users.
The SparkFun Qwiic ADC does need a few additional items for you to get started; a Qwiic enabled microcontroller, a Qwiic cable, and jewelry/precision screwdrivers (with 1.5mm and 2.5mm flathead bits). You may already have a few of these items, so feel free to modify your cart based on your needs.
If you're unfamiliar with analog to digital converters, jumper pads, or I2C be sure to checkout some of these foundational tutorials.
