Very nice sight accurate reading, and performance

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.

I tested out this board and it functions perfectly to a high degree of precision. The board itself is very well made and easy to hook-up. Comes with a convenient wiring loom and 4 independent input channels.The chip in the picture on the description page shows the markings of a genuine TI - ADS1115 chip but the board I received didn't have any markings on the chip - the top of the chip has no markings. However, as I said - the readings are accurate with no issues.HIGHLY RECOMMENDED! AAA+++

This one did not work correctly and neither did their software for it. Tried different versions from different suppliers (Adafruit being one of them and DFRobot the other) and all had the same result. I had expected this since they all are written function with an ADS1115. Customer support was contacted and I was told again to install their software...it does not work...Item was returned. Unfortunately after this experience, I will purchase another brand..

El producto llegó antes del tiempo programado, y cumplió con lo esperado.

Primo modulo mai acquistato da utilizzare assieme ad arduino. Molto semplice il collegamento sui pin per la comunicazione in protocollo I2C, semplici anche gli script python che sono statti scritti permettendo di applicare anche un fattore di scala sulla lettura. Utilizzati 2 in serie grazie al selettore per variare l'indirizzo.

Die Produktverpackung besteht aus einer Kunststoffbox, die man nach dem Aufbau auch als Aufbewahrungsbox nutzen kann. Die Platine wird in einer antistatischen Folie aufbewahrt, damit sich durch Reibung nichts elektrisch aufladen und beschädigen kann.Eine Anleitung liegt nicht dabei, dafür ist alles auf der Wiki Seite vom Hersteller zu finden, auch ein Test Code für den Arduino und den Raspberry Pi.Dieses Modul wandelt analoge Signale in digitale Signale um, als Wandler wird ein 16-Bit-ADC-Chip ADS1115 verwendet. Die Betriebsspannung kann zwischen 3,3V und 5V liegen.Der Chip verfügt über eine präzise Referenzspannung und eine programmierbare Verstärkungsanpassung, sodass er auch für schwache und schwankende Signale geeignet ist.Es können bis zu 4 analoge Signale gleichzeitig ausgelesen werden.Auf der Platine befinden sich noch ein kleiner Schalter, womit man zwischen zwei I²C Adressen wechseln kann.Die Modulmaße ohne Kabel sind ca.: 32mm (L) x 32mm (B) x 11,5mm (H) inklusive Stiftleisten.Die Erweiterungsplatine funktioniert wie erwartet reibungslos, man sollte sich aber mit Arduino oder mit dem Raspberry Pi auskennen, um es ans Laufen zu bekommen. Für komplette Anfänger könnte es vielleicht etwas schwierig werden.Preis Leistung von ca. 14€ ist für den deutschen Markt noch in Ordnung, woanders sind so ähnliche Module um die Hälfte günstiger, die Platine ist dann aber auch weniger bestückt und es liegt kein Kabel dabei.Von den Funktionen her ist soweit alles in Ordnung, ein paar Tests auf dem Arduino liefen auch problemlos. Es ist auch eine klasse Erweiterung für den Raspberry Pi, denn er hat keine analogen Pins.

Pas encore testé réellement mais fait partie d'un futur projet de programmation et autres avec Arduino.Module de qualité.iNterface pratique pour pouvoir utiliser les capteurs analogiques avec Arduino (entrées uniquement digitales).Prix : 15€
