Product overview
Description
The X-NUCLEO-AMICAM1 expansion board allows synchronized acquisition and streaming of up to 4 microphones at a maximum sampling rate of 192 KHz.
It represents a quick and easy solution to develop microphone-based applications and start implementing audio algorithms.
The expansion board is designed around the MP23ABS1 analog MEMS microphone and is compatible with the ST morpho connector layout and with analog microphone coupon boards (e.g., STEVAL-MIC004V1).
The X-NUCLEO-AMICAM1 embeds three MP23ABS1 microphones: two connected to an external ADC and one directly routed to the STM32 embedded ADC.
The analog amplification stage is achieved thanks to ST TSV91x wide bandwidth operational amplifiers.
