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.\u003c\/p\u003e\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003egator:bit Compatible\u003c\/li\u003e\n\u003cli\u003eADS1015\n\u003cul\u003e\n\u003cli\u003eOperating Voltage (V\u003csub\u003eDD\u003c\/sub\u003e): 2.0V-5.5V\u003c\/li\u003e\n\u003cli\u003eOperating Temperature: -40°C to 125°C\u003c\/li\u003e\n\u003cli\u003eOperation Modes: Single-Shot, Continuous-Conversion (Default), and Duty Cycling\u003c\/li\u003e\n\u003cli\u003eAnalog Inputs:\n\u003cul\u003e\n\u003cli\u003eMeasurement Type: Single-Ended (Default)\u003c\/li\u003e\n\u003cli\u003eInput Voltage Range: GND to V\u003csub\u003eDD\u003c\/sub\u003e\n\u003c\/li\u003e\n\u003cli\u003eFull Scale Range (FSR): ±.256V to ±6.114V (Default: 2.048V)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eResolution:\n\u003cul\u003e\n\u003cli\u003e12-bit (Differential) or 11-bit (Single-Ended)\u003c\/li\u003e\n\u003cli\u003eLSB size: 0.125mV - 3mV (Default: 1 mV)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eSample Rate: 128 Hz to 3.3 kHz (Default: 1600SPS)\u003c\/li\u003e\n\u003cli\u003eCurrent Consumption (Typical): 150μA-200μA\u003c\/li\u003e\n\u003cli\u003eI\u003csup\u003e2\u003c\/sup\u003eC Address: 0x48\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eElectret Microphone\n\u003cul\u003e\n\u003cli\u003eOperating Voltage: 1.5V (Max 10V)\u003c\/li\u003e\n\u003cli\u003eSupply Current: 0.3mA (Max)\u003c\/li\u003e\n\u003cli\u003eDirectivity: Omnidirectional\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 20-16,000Hz\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003eLMV324 Op-amp\n\u003cul\u003e\n\u003cli\u003eOperating Voltage: 2.7V-5.5V\u003c\/li\u003e\n\u003cli\u003eSupply Current: ~300-720µA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eDocuments\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/a\/8\/5\/e\/6\/gator_microphone_Schematic.pdf\" target=\"_blank\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/e\/6\/8\/6\/f\/gator_microphone.zip\" target=\"_blank\"\u003eEagle Files\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/learn.sparkfun.com\/tutorials\/sparkfun-gatormicrophone-hookup-guide\" target=\"_blank\"\u003eHookup Guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/4\/6\/f\/a\/b\/Electret_Microphone.pdf\" target=\"_blank\"\u003eDatasheet\u003c\/a\u003e (Electret Microphone)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/9\/7\/a\/c\/7\/LVM324.pdf\" target=\"_blank\"\u003eDatasheet\u003c\/a\u003e (LVM324)\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/6\/5\/6\/2\/a\/ADS1015.pdf\" target=\"_blank\"\u003eDatasheet\u003c\/a\u003e (ADS1015)\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/pxt-gator-microphone\" target=\"_blank\"\u003egator:microphone PXT Package\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/github.com\/sparkfun\/gator_microphone\" target=\"_blank\"\u003eGitHub Hardware Repo\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Sparkfun","offers":[{"title":"Default Title","offer_id":29403623718995,"sku":"SEN-15289","price":8.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0174\/1800\/products\/15289-SparkFun_gator-microphone_-_micro-bit_Accessory_Board-01.jpg?v=1563269019","url":"https:\/\/shop.pimoroni.com\/en-eu\/products\/sparkfun-gator-microphone-micro-bit-accessory-board","provider":"Pimoroni Ltd","version":"1.0","type":"link"}
