Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they're way smaller and thinner. This microphone doesn't even have analog out, it's purely digital. The range is about 50Hz - 15KHz, good for all general audio recording/detection.

This breakout board features the easy-to-use MCP4725 12-bit DAC. Control it via I2C and send it the value you want it to output, and the VOUT pin will have it. Great for audio / analog projects, such as when you can't use PWM but need a sine wave or adjustable bias point. Works with both 3.3V or 5V logic.

This breakout makes I2S digital audio easy: all you need to do is power it with 3~5VDC, and provide BCLK (bit clock), WSEL (left/right word select), and DIN (data in). The data lines are 3.3V logic only. You can use 3.5mm jack or header pins for output and it'll work with any I2S capable microcontroller, e.g. ESP32 or Raspberry Pi. It has line level output, i.e. you can connect it to stereo amplifier or active speakers but not to headphones.

This small mono amplifier is surprisingly powerful - able to deliver 3.2 Watts of power into a 4 ohm impedance speaker. Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, it's incredibly efficient - making it perfect for portable and battery-powered projects. Works great with Raspberry Pi, Arduino Zero, and any other microcontroller or microcomputer with I2S audio outputs.
