“ADS1115 16-Bit ADC - 4 Channel with Programmable Gain Amplifier”

For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1115 provides 16-bit precision at 860 samples/second … read more

The Adafruit libraries for this are no longer supported, but still available. On the other hand the Gravity version is cheaper and the library is still supported. However for a python novice, the Adafruit example is a lot easier to follow and understand! Does Core have any views on ease of programming in python/raspberry pi of these two?

Hi Steven,

Sorry we missed your question. Adafruit have deprecated the python library but the circuitpython library should be a good substitute which is still maintained.
Since both boards are using the same ADS1115 module you may find that either library works just fine on either module, I don’t imagine the supporting hardware will be very different in either design, just double-check the pinouts!


thanks, I mistakenly thought that circuitpython and python were mutually exclusive, but it turns out that you can use the circuitpython libraries in python on RPi.

Another discovery I made - the ADS1115 datasheet and docs don’t exactly make it clear, but the continuous sampling mode is really only useable for a single channel at a time. So you can’t read all 4 channels in continuous mode. If you want to read all 4, you have to read each channel individually in single shot mode. That was a disappointing discovery :frowning:
