Product description
12-bit ADC with 4 channels and screw terminal. Based on the ADS1015 which adds analog inputs to the microcontroller. Communicates via I²C and can be connected using Qwiic or header pins to a breadboard. The four analog inputs can be used as single-ended or as two differential channels. The integrated programmable gain amplifier (PGA) makes it possible to measure small signal variations with improved resolution within the selected measurement range. The ADS1015 uses an internal reference and supports multiple operating modes, including single-shot and continuous conversion, providing flexibility for both low-power and real-time applications. There is a 10K trimpot connected to channel A3. It is convenient for initial setup testing and can be used as a simple variable input for your project. The function can be disconnected via solder jumper if not desired, allowing A3 to operate like the other inputs.
