ADS1115
ADS1015

The ADS1115 and ADS1015 4-channel breakout boards are perfect for adding high-resolution analog to digital conversion to any microprocessor-based project.  These boards can run with power and logic signals between 2v to 5v, so they are compatible with all common 3.3v and 5v processors.  As many of 4 of these boards can be controlled from the same 2-wire I2C bus, giving you up to 16 single-ended or 8 differential channels.  A programmable gain amplifier provides up to x16 gain for small signals.

These two boards are very similar, differing only in resolution and speed. The ADS1115 provides 16-bit precision at 860 samples/second, while the ADS1015 provides 12-bit precision at 3300 samples/second.

To get you going fast, we spun up a custom-made PCB in the STEMMA QT form factor, making it easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and either the ADS1115 or ADS1015. You can chain the boards with a wide range of other sensors and accessories using a compatible cable.
