DS1115 Precision ADC module
The ADS1115 analog-to-digital converter provides high-precision, 16-bit precision at 860 samples/second over I2C. The chip can be configured as 4 single-ended input channels, or two differential channels. As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range. We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use. It is a great general purpose 16 bit converter.

I2C Addressing
The ADS11x5 chips have a base 7-bit I2C address of 0x48 (1001000) and a clever addressing scheme that allows four different addresses using just one address pin (named ADR for ADdRess). To program the address, connect the address pin as follows:
- 0x48 (1001000) ADR - GND
- 0x49 (1001001) ADR - VDD
- 0x4A (1001010) ADR - SDA
- 0x4B (1001011) ADR - SCL
