Arduino ABX00031 - Color and als Detection; Digital Microphone; Power Tree

Arduino® Nano 33 BLE Sense
8 / 14 Arduino® Nano 33 BLE Sense Modified: 29/05/2023
2.7.3 Color and ALS Detection
The Color and ALS detection feature provides red, green, blue and clear light intensity data. Each of the R, G, B, C channels have a UV
and IR blocking filter and a dedicated data converter producing16-bit data simultaneously. This architecture allows applications to
accurately measure ambient light and sense color which enables devices to calculate color temperature and control display backlight.
2.8 Digital Microphone
The MP34DT05 is an ultra-compact, low-power, omnidirectional, digital MEMS microphone built with a capacitive sensing element and
an IC interface.
The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process
dedicated to produce audio sensors
2.9 Power Tree
The board can be powered via USB connector, V
IN
or V
USB
pins on headers.
Power tree
NOTE: Since V
USB
feeds V
IN
via a Schottky diode and a DC-DC regulator specified minimum input voltage is 4.5V the minimum supply
voltage from USB has to be increased to a voltage in the range between 4.8V to 4.96V depending on the current being drawn.
