5Pcs ADS1015 Mini 12bit Analog-to-Digital Converter ADC Development Board CJMCU for Arduino - products that work with official Arduino boardsDescription: For microcontrollers without an analog to digital converter or when you want a higher precision ADC, the ADS1015 provides 12 bit precision at 3300 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
