INTRODUCTION
DFRobot I2C ADS1115 16-bit ADC module can accurately collect and convert analog signals. Through this ADC module, Raspberry
Pi can easily use a wide range of Gravity series analog sensors to measure various signals, and perceive this world.
Raspberry Pi is a common master control board which is powerful in its functions, but the I/O pins of Raspberry Pi can read digital
signals only, what's more, only through an external analog-to-digital conversion (ADC) module can it read signals of analog sensor
or device, it is not convenient to use.
DFRobot I2C ADS1115 16-bit ADC module is specially designed for Raspberry Pi and Gravity series analog sensors, which greatly
reduces the difficulty of using the Gravity series analog sensors, plug and play, no welding, very convenient. The number of Gravity
series sensors is large and its wide variety can meet the needs of various sensors of the Raspberry Pi.
This module uses 16-bit ADC chip ADS1115, supports 3.3 ~ 5V wide voltage power supply. The chip has a precision reference
voltage and programmable gain adjustment (PGA), therefore, accurate acquisition and conversion can be performed for both weak
and highly variable signals. So it is also applicable to all types of applications that the main control board needs to accurately
collect the analog signals.
One ADC module can read analog signals of 4 channels. Because of the on-board I2C address selection switch, it supports the
cascade of two ADC modules and can read analog signals of 8 channels, it can satisfy the needs of various applications.
