For Raspberry Pi boards without an analog-to-digital converter, or when you need a more accurate ADC, we provide this 4-channel ADC based on Texas Instrument ADS1115 for you. It is a high-precision, low-power, 16-bit ADC chip. We make this ADC into a compact Raspberry Pi Zero form factor and integrated an analog Grove connector so that you can also use analog Grove modules with it.

It is an excellent analog to digital converter with programmable gain and high resolution. You can use it as general purpose 16 bit ADC HAT for Raspberry Pi 3B/3B+/4 and Arduino series. It provides 4 Analog pins, and its sample rate is 8 SPS to 860 SPS(samples per second).

To help you get started provide a detailed guide on the Wiki page, as well as the ADS1115 Software Library, ADS1115 Datasheet, and example code for this 4-channel 16-bit ADC for Raspberry Pi (ADS1115). With this ADC guide, you can easily run the example code to start reading data.
