2X ICS-43434 I2S 3.3V MEMS Microphone Module Breakout Low Cost Low Pass Filter Mini Module

This I2S MEMS microphone is bottom ported, so make sure you have holes on the bottom, towards the sound you want to read. It's only the largest device at 1.6-3.6V, so it won't work with 5V logic (you're unlikely to use an I2S 5V logic device anyway). Many beginner microcontroller boards don't have i2, so make sure it's a supported interface before trying to put it all together! The microphone is best used with cortical M-series chips such as SAMD21 or SAMD51, ESP32, RP2040 or RP2350, or RASPBERRY PI (e.g. Raspberry Pi). Sensitivity: 26 dB FS 1dB High performance mode SNR: 65dBA Low power mode SNR: 64dBA High performance mode current consumption: 490μA Low power mode Current consumption: 230μA Mike Wind Pressure Level Overload Point (AOP): 120 dB SPL High performance mode sampling rate: 23 ~ 51.6kHz Low power mode sampling rate: 6.25 ~ 18.75 kHz (Pin headers have been soldered) Color: As Shown Material: PCB Package Contents: 2 x Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
