The ADS1115 is an external 16-bit ADC + a built-in programmable gain amplifier (or PGA), which can be very useful for certain Arduino and ESP8266 projects. This is ideal when more resolution or more analogue pins are required. You get better accuracy, as well as relieving the processor of this burden.
