• 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 analog 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 *** 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.
• The micro:bit is a pocket-sized computer that lets you get creative with digital technology. Between the micro:bit and our shield-like bit boards you can do almost anything while coding, customizing and controlling your micro:bit from almost anywhere! You can *** your micro:bit for all sorts of unique creations, from robots to musical instruments and more. At half the size of a credit card, this versatile board has vast potential!
