This board consists of Arduino-compatible hardware which includes an OLED display, ADS1115 4-Channel 16Bit ADC, Arduino-compatible Microcontroller ATMEGA328, a connector for Arduino Programming, a connector for 4 Channel Analog input, and a connector for a couple of I/O lines. Operating supply 5V DC.

The ADS1115 device is a precision, low-power, 16-bit, I2C-compatible, analog-to-digital converter (ADCs). It incorporates a low-drift voltage reference and an oscillator. The ADS1115 also incorporates a programmable gain amplifier (PGA) and a digital comparator. These features, along with a wide operating supply range, make the ADS1115 well-suited for power- and space-constrained, sensor measurement applications.

The ADS1115 performs conversions at data rates of up to 860 samples per second (SPS). The PGA offers input ranges from ±256 mV to ±6.144 V, allowing precise large- and small-signal measurements. The ADS1115 features an input multiplexer (MUX) that allows two differential or four single-ended input measurements. Use the digital comparator in ADS1115 for under and overvoltage detection.

The ADS1115 operates in either continuous-conversion mode or single-shot mode. The devices are automatically powered down after one conversion in single-shot mode; therefore, power consumption is significantly reduced during idle periods.
