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 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. 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 use 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!   GET STARTED WITH THE SPARKFUN GATOR:MICROPHONE HOOKUP GUIDE   FEATURES gator:bit Compatible ADS1015 Operating Voltage (VDD): 2.0V-5.5V Operating Temperature: -40°C to 125°C Operation Modes: Single-Shot, Continuous-Conversion (Default), and Duty Cycling Analog Inputs: Measurement Type: Single-Ended (Default) Input Voltage Range: GND to VDD Full Scale Range (FSR): ±.256V to ±6.114V (Default: 2.048V) Resolution: 12-bit (Differential) or 11-bit (Single-Ended) LSB size: 0.125mV - 3mV (Default: 1 mV) Sample Rate: 128 Hz to 3.3 kHz (Default: 1600SPS) Current Consumption (Typical): 150μA-200μA I2C Address: 0x48 Electret Microphone Operating Voltage: 1.5V (Max 10V) Supply Current: 0.3mA (Max) Directivity: Omnidirectional Frequency Response: 20-16,000Hz LMV324 Op-amp Operating Voltage: 2.7V-5.5V Supply Current: ~300-720µA DOCUMENTS Schematic Eagle Files Hookup Guide Datasheet (Electret Microphone) Datasheet (LVM324) Datasheet (ADS1015) gator:microphone PXT Package micro:bit Information Page GitHub Hardware Repo
