PDM Interface Module yogwiritsidwa ntchito poyesa ma audio a maikolofoni a digito a MEMS

Wonjezerani chowunikira mawu cholowetsa / chotulutsira chizindikiro

USD 2,140.00

Kusinthasintha kwa ma pulse PDM imatha kutumiza zizindikiro mwa kusintha kuchuluka kwa ma pulse, ndipo nthawi zambiri imagwiritsidwa ntchito poyesa ma audio a maikolofoni a digito a MEMS.

Module ya PDM ndi gawo losankha la chowunikira mawu, chomwe chimagwiritsidwa ntchito kukulitsa mawonekedwe oyesera ndi ntchito za chowunikira mawu.
