DESCRIPTION
The SparkFun gator:microphone is a micro:bit Accessory Board that integrates an electret microphone into SparkFun’s gator:bit series of gator clippable accessories, enabling it to be easily interfaced with the micro:bit or other microcontrollers! It provides a binary indication of the presence of sound and an analogue representation of its amplitude.
The gator:microphone consists of four pads for power and data. There is also a switch on the board to select different audio amplification levels. Additionally, it includes an LMV324 operational amplifier (op-amp) for processing the audio signals from the microphone. The specified operating voltage for the VEML6070 is between 2.7V-5.5V. For use with the gator:bit (v2) and micro:bit, you should provide 3.3V through the 3V3 and GND pads to keep the logic levels consistent.
