PmodMIC3 ke MEMS Microphone e tsamaisoang ke Knowles Acoustics SPA2410LR5H-B le Texas Instruments ADCS7476. Basebedisi ba ka fetola molumo o kenang ho boto ea tsamaiso ka potentiometer e nyenyane pele ba amohela likotoana tsa 12 tsa data ka SPI. PmodMIC3.
Likarolo li kenyelletsa:
- MEMS Microphone module e nang le sebopeho sa dijithale
- Fetolela li-audio input ka 12-bit A/D converter
- Fetola molumo o kenang ka potentiometer ea onboard
Tlhaloso ea Ts'ebetso
PmodMIC3 e etselitsoe ho tlaleha ka dijithale ho boto e amohelang batho neng kapa neng ha e bona lerata lefe kapa lefe la kantle. Ka ho romela moemeli oa boleng ba dijithale oa 12-bit oa khafetsa le molumo oa lerata, nomoro ena e ka sebetsoa ke boto ea sistimi mme ea etsa hore molumo o amoheloang o hlahisoe ka nepo ka sebui. Potentiometer e ka holim'a board e ka sebelisoa ho fetola phaello ho tsoa ho maekrofono ho ea ho ADC.
