Review: A TO D AT 16 BIT - Ok good well labeled some tutorial available.
Review: This one was defective and the suggested software would not work.. - 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..

## Features

- Raspberry Pi is a common main control board with powerful functions. However, the pins of the Raspberry Pi main control board can only read digital signals. If you need to read the signals of analog sensors or devices, you can only connect an analog-to-digital conversion (ADC) module, which is not convenient to use.
- The ADS1115 16-bit AD conversion module can accurately collect and convert analog signals. Through this AD module, the Raspberry Pi main control board can be very conveniently compatible with the Arduino series of analog sensors, measure various signals, and perceive this world.
- ADS1115 16-bit AD conversion module is specially designed for Raspberry Pi compatible with Arduino series analog sensors, which greatly reduces the difficulty of Raspberry Pi main control board compatible with Arduino series analog sensors, plug and play, no soldering, very convenient.
- This module uses the 16-bit ADC chip ADS1115, which supports a wide voltage supply from 3.3V to 5V. The chip has a precision reference voltage and programmable gain adjustment (PGA), so it can be used for weak signals or signals with large changes. Accurate acquisition and conversion, so this module is also suitable for all kinds of occasions where the main control board needs to accurately collect analog signals.
- One AD module can read 4 channels of analog signals. Due to the onboard I2C address selection switch, it supports the cascade of 2 AD modules and reads 8 channels of analog signals, which is sufficient to meet the needs of various scenarios.

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.
