Review on High-performance 16Bit ADC with Built-in PGA for RPI Raspberry PI - I2C ADS1115 Module ADC with 4 Channels, Ideal for Raspberry Pi 3/2 Model B/B+ by Juan Anderson

I preferred it to Adafruit because it had a terminal strip. At first I was disappointed by the lack of documentation. Then I saw the http link but I copied the entire link including the dot and got a blank links page. After looking at the Adafruit site for a bit, I went back and copied the http link non-stop and saw a very good tutorial. Installed according to instructions, everything ok. It's very stable. To test this I bought a DROK 4-20mA generator, a 15-30V DC signal converter from Revain. The ADC tracks the signal generator closely. Some more expensive ADCs cannot handle such differential voltages.
