Perfect for sensor projects
This ADS1015 module works flawlessly with my Arduino Uno. The I2C communication is stable, and the 12-bit resolution is more than enough for reading temperature and light sensors. Setup was easy using the Adafruit library.

Essential for learning ADC
Bought this for my university electronics course. It's much easier to use than building an ADC circuit from scratch. The programmable gain amplifier is a nice feature to have when dealing with weak signals.

Reliable and compact
I've integrated four of these into my robot controller board. They take up very little space and provide consistent readings. The wide voltage range makes it compatible with both 3.3V and 5V logic systems.

Good value, clear documentation
Great little board for the price. It handles differential inputs well which was exactly what I needed for a strain gauge project. Only minor issue is the header pins were slightly loose, but a quick solder fixed it.

Works as advertised
Solid performance for general data logging. The sampling rate is sufficient for slow-changing signals like battery voltage monitoring. Would recommend checking the address jumpers if you plan to use multiple units on one bus.

Excellent precision for the cost
Compared to the internal ADC on my microcontroller, this external module offers significantly better noise immunity and accuracy. Highly recommended for any serious instrumentation project.
Q: Can this module be used with a 3.3V Raspberry Pi?
A: Yes, the ADS1015 operates from 2.0V to 5.5V, so it is fully compatible with 3.3V Raspberry Pi GPIO pins without needing a level shifter.
Q: Is there a library available for Python?
A: Yes, the popular Adafruit CircuitPython library supports the ADS1015 and works seamlessly with Raspberry Pi and other CircuitPython-compatible boards.
Q: How do I change the I2C address to use multiple modules?
A: The board has an address selection pin (ADDR). By connecting this pin to VDD, GND, SDA, or SCL, you can select one of four different I2C addresses, allowing up to four modules on the same bus.
Q: Does this come with header pins soldered?
A: No, the module typically ships with unsoldered header pins to allow for flexible mounting options. You will need to solder them yourself or use female-to-female jumper wires directly on the pads.
Q: What is the maximum input voltage I can measure?
A: The maximum input voltage depends on the PGA gain setting. With the lowest gain (2/3), you can measure up to roughly +/- 6.144V, but ensure the input never exceeds the supply voltage plus 0.3V to avoid damage.
