You can select whether you want it to be\non the Left or Right channel by connecting the Select pin to power or ground.\nIf you need stereo, pick up two microphones! You can set them up to be stereo\nby sharing the Clock, WS and Data lines but having one with Select to ground,\nand one with Select to high voltage. This I2S MEMS microphone is bottom\nported, so make sure you have the hole in the bottom facing out towards the\nsounds you want to read. It's a 1.6-3.6V max device only, so not for use with\n5V logic (its really unlikely you'd have a 5V-logic device with I2S anyways).\nMany beginner microcontroller boards don't have I2S, so make sure its a\nsupported interface before you try to wire it up! This microphone is best used\nwith Cortex M-series chips like the for Arduino Zero, for Feather M0, or\nsingle-board computers like the for Raspberry Pi. Specifications : Input\nvoltage: DC 1.6V-3.6V. Connection interface: I2S interface. Work temperature:\n-25°C ~ 85°C. Work humidity: 5%~95%RH. Size: 17 x 13 x 3 mm. Features: 1).It\ncomes with a MEMS microphone,which is more convenient to use. 2).Its working\nvoltage is small,and it can be used when it meets the input voltage\nrequirements. 3).You can set them up as stereo by sharing the clock,WS and\ndata lines,but one chooses ground and the other chooses ground. 4).This\nmicrophone can be used with Cortex M series chips.
