4-Channel 16-Bit ADC for Raspberry Pi (ADS1115); 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 a 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).
