CQRobot ADS1115 16-Bit ADC Conversion Module Compatible with Raspberry Pi and Arduino Boards. Achieve Analog and Digital Signal Acquisition or Conversion, 3.3V to 5V, I2C Address Selection Switch.

Very nice ADS does the job and working as intended so far. Recommend!

Came well packed and build quality looks good.All inputs and outputs are clearly marked on board.Little to no information supplied with product, just a couple of references to webpages on packet label.A basic specification sheet was found after a search on the CQRobot webpage, as well as a link to a wiki page containing examples for use with both an Arduino and a Raspberry Pi.Using the examples it was relatively easy to get the board up and running once relevant libraries were installed.Could only test with Arduino but results showed the board basically does what one would expect. Its 16 bit resolution plus the use of on board stable reference voltage gave more accurate voltage readings when compared to the Arduinos analogue read input which is only 10bit and only uses Vcc as a reference voltage.Some good features include being able to scale down the input voltage range to enable even better accuracy at low voltage measurements and its ability to do differential input measurements enabling both positive and negative voltages to be measured.Found no negatives when using the board.At £11.99 value for money is difficult to assess as it is dependent on the user’s individual project needs in terms of what they require to measure (positive and/or negative voltages) and the voltage accuracy required. It's not going to break the bank though.

I've used the ADS1115 before, it's a great chip. Not sure where I would need 16bit precision, I usually oversample and decimate which is almost as good.This module is OK, construction is good (not perfect but still a good standard) and seems to function OK. I think the ENIG finish is a bit OTT and only for looks, otherwise a great little board.Would expect to pay less than £10 for one.

This ADS1115 module is a convenient device for adding a 16bit analog port to the Raspberry Pi. The module works via I2C (it can be switched between addresses 0x48 and 0x49 via the on-board switch) and so only needs 4 wires connected to the Pi GPIO pins. The A0 to A3 ports are conveniently arranged next to 0V and Vcc (3.3V) pins on the board, making it easy to quickly check if the device is working. There are also 4 pins on the side of the board that extend the I2C bus, if you wanted to daisy-chain another CQRobot module or other I2C device.I followed the URL in the description, and copied the Python example code there, and it only took about 5 minutes to get the board reading a voltage on pin A1 (I connected it to a solar cell that I had to hand, getting a 2V reading). I also installed the Adafruit ADS1115 library, and this works also, so you can use this if you find it more convenient.

The form of this ADC is very neat. The item is as showing in the listing.This is an Analogue-to-Digital converter. The main use for this would be connecting an analogue input to a raspberry pi as those are digital computers. Arduino boards don't necessarily need this as they have analogue inputs on the board. This can also be used to add extra pins, but also being analogue.Since this uses the I2C interface, just remember that if this is your first time using this, that you have to enable i2c. There is a somewhat vague tutorial on the wiki. In the test code that they have provided, they have put the files in separate folders, which I thought was odd, and was only figured out when I saw the photo of the terminal the attached.This just makes the Raspberry Pi just that much more versatile now. Definitely recommend.It also comes in a small box so you can store it without it getting tangled up.

My partner urged me to order this and he says - This is an excellent analogue to digital converter module for the Arduino/ Raspberry PI that is obviously well made and of high quality when examined and tested. There is far more to this than a typical ADS1115 and is designed to facilitate easy use by Arduino and Raspberry PI. This enables the conversion of high resolution analogue inputs and coverts them to digital signals. A single board allows 4 such inputs and with 2 additional boards a total of 8. It is worth paying the bit extra when compared to the basic ADS1115 if you need this functionality for your projects.

This is ESSENTIAL if you are going to connect a wide range of Arduino compatible sensors to a Raspberry Pi. The sensors need to have their signal output transformed in order for the Raspberry Pi to be able to use them and so you will need one of these modules if you are going to use them.

ADC PCB module for Raspberry Pi / Microcontrollers with I2C communication. Very easy to connect and requires little wiring experience. 16 bits is plenty adequate for my needs, as I have bee using it for current sensing and potentiometer readings. Would recommend!
