Nicla Sense ME is the smallest Arduino-developed board equipped with a range of the latest Bosch environmental and motion sensors. The module is based on the nRF52832 ARM Cortex M4 chip clocked at 64 MHz with 512 kB of Flash, 64 kB of RAM and 2 MB of SPI Flash and 2 MB of QSPI embedded memory. The Nicla Sense ME features the Bosch BHI260AP, BMP390, BMM150 and BME688 embedded sensors. 

The MAX9812 is a sound amplifier specially designed to treat the signal coming from microphones.
We can use it together with Arduino to measure sound from a processor like Arduino.
When we saw the modules with microphone we commented that, in general, the signal generated is too low to be registered correctly.
If we want to be able to measure sounds, we will have to amplify the signal. The MAX9812L has single / dual inputs, fixed gain of 20dB, bandwidth of 400 kHz, low noise and low signal distortion 0.015% THD.
There are two models, its supply voltage is 2.7V to 3.6V.
We can use the sensors with MAX9812 for applications that require measuring the intensity or frequency of the sound.

It can be used to control the microprocessor of the Arduino AVR PIC system and others, or as a digital potentiometer rotating the rotary encoder can be counted in positive and negative, depending on the direction of rotation; with the button of the rotary encoder can be reset to its initial state, which starts counting from 0.

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.
