High precision
Much better than the built-in ADC on my Arduino Uno. I use this for audio envelope detection and it handles the dynamics well.

Good value but small pins
Works as expected for the price. The pins are a bit close together for breadboarding without an adapter, but performance is solid.

Perfect for sensor logging
Needed extra ADC pins for my weather station. This module works flawlessly with my ESP32. Readings are stable and consistent.

Reliable component
Bought three for a robot project. All three performed identically. Highly recommend for anyone needing precise analog readings.

Documentation scarce
Hardware is fine, but had to dig around forums to find the right library settings for the gain configuration. Works once set up.
Q: What is the maximum input voltage range?
A: The PGA allows up to ±6.144V, but ensure common mode limits are respected based on your supply voltage.
Q: Can it measure differential signals?
A: Yes, it supports 2 differential input pairs or 4 single-ended inputs depending on your configuration.
Q: Can I change the I2C address?
A: Yes, there are address selection pins available on the breakout board to configure different addresses.
Q: Is there an Arduino library available?
A: Yes, the Adafruit ADS1X15 library works perfectly with this module and is easy to implement.
Q: Does this work with 3.3V logic?
A: Yes, it supports 2.0V to 5.5V supply, so 3.3V logic levels are fully compatible.
