For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. Adafruit like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 12 bit converter.

The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet. Interfacing is done via I2C. The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs.

To get you started, Adafruit have example code for both the Raspberry Pi (in Adafruit's Adafruit Pi Python library) and Arduino (in Adafruit's ADS1X15 Arduino library repository) Simply connect GND to ground, VDD to your logic power supply, and SCL/SDA to your microcontroller's I2C port and run the example code to start reading data.

  • We've built a mass SD card writer using a Raspberry Pi 3 Model B, some USB hubs and SD card readers. This beast has enough ports to write 49 SD cards at once! At Core Electronics, sometimes logistics hang-ups mean that suppliers cannot meet our demand for pre-flashed SD cards. During these periods we have to pick up the slack by manually imaging blank SD cards we source ourselves. Of course, this is a super-tedious process, and ...

    Excellent and versatile board. I installed it in a Pyranometer on the top of the roof. Added a couple of pull-ups and it is running error free across 8metres of Cat5E cable at 100kHz to a Beaglebone Black.

    The Adafruit python and C libraries made development and integration very simple. (Posted on 9/03/2016)

    We used this product to extend the ADC channel required to facilitate new sensors. Very nice and easy to interface. Within 3 days I designed our new PCB. Highly recommended! (Posted on 18/03/2014)
