The MP34DT05 digital MEMS microphone is omnidirectional and operate via a capacitive sensing element with a
high (64 dB) signal to noise ratio. The sensing element, capable of detecting acoustic waves, is manufactured using
a specialized silicon micromachining process dedicated to producing audio sensors (U6).
3.9 Power Tree
Nicla Vision Power Tree
Input voltage can be provided to the Nicla Vision through the USB connector (J7), the ESLOV connector (J5), battery
connector (J4) or alternatively the headers. The USB connector is prioritized over the ESLOV connector, both of
which are prioritized over the battery connector and header. Reverse polarity protection for the USB connector (J7)
and the ESLOV connector (J5) are provided by ideal diodes U2 and U7 respectively. Input voltage from the battery
does NOT have reverse polarity protection and the user is responsible for respecting the polarity.
A NTC (negative thermal coefficient) sensor provides overtemperature shutoff to the battery. The battery fuel
gauge provides indication of the remaining battery capacity
There are three main power lines provided:
