TECNOIOT 2pcs SPH0645 I2S MEMS Microphone Breakout Sensor Board Module SPH0645LM4H DC 1.6-3.6V

【SPH0645】The microphone is a single mono element. You can select whether you want it to be on the Left or Right channel by connecting the Select pin to power or ground. If you need stereo, pick up two microphones!You can set them up to be stereo by sharing the Clock, WS and Data lines but having one with Select to ground, and one with Select to high voltage. 【Design compact】This I2S MEMS microphone is bottom ported, so make sure you have the hole in the bottom facing out towards the sounds you want to read. It's a 1.6-3.6V max device only, so not for use with 5V logic (its really unlikely you'd have a 5V-logic device with I2S anyways). 【Easy operation】Many beginner microcontroller boards don't have I2S, so make sure its a supported interface before you try to wire it up! This microphone is best used with Cortex M-series chips like the for Arduino Zero, for Feather M0, or single-board computers like the for Raspberry Pi. 【Specifications】✔Input Voltage:DC 1.6V-3.6V✔Connection Interface:I2S interface✔Work Temperature:-25℃~85℃✔Work Humidity:5%~95%RH✔Size:17*13*3mm✔1).It comes with a MEMS microphone,which is more convenient to use.✔2).Its working voltage is small,and it can be used when it meets the input voltage requirements.✔3).You can set them up as stereo by sharing the clock,WS and data lines,but one chooses ground and the other chooses ground. ✔4).This microphone can be used with Cortex M series chips. 【Note】✔1).The bottom of this I2S MEMS microphone is the port,so make sure the hole on the bottom is facing the sound you want to read. ✔2).It's only a 1.6-3.6V capable device,so it won't work with 5V logic.
