Pmod MIC3: MEMS Microphone with Adjustable Gain

The Pmod MIC3 is a MEMS Microphone powered by the Knowles Acoustics SPA2410LR5H-B microphone and the Texas Instruments ADCS7476 analog-to-digital converter. Users may adjust the incoming volume to the system board with the small potentiometer before they receive the 12 bits of data through SPI.

Note:

The Pmod MIC3 is also featured in a fantastic product bundle, the Arty S7 Pmod Pack! This bundle was designed to expand project possibilities by utilizing a variety of peripheral modules perfectly suited for the Arty S7 FPGA.
