CQRobot ADS1115 16-Bit ADC Conversion Module for Arduino/Raspberry Pi

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

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.

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!

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.

Another great board from CQRobot. As with all their boards, this is well made and feels solid. Solder points are clean, and the connectors well labeled. The leads are very flexible with soft sleeves, and comes supplied with a nice velcro strap. The board has four ADC connections, two sets of I2C pins, and an I2C address select jumper. The ADC convertor works just as expected, providing 16 bit digital data from the four analog inputs. Very easy to set up and use.

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 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.

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.

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.

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€

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

Ok good well labeled some tutorial available.
