Product Reference Manual
SKU: ABX00069
Description
The Arduino Nano 33 BLE Sense Rev2 is a miniature sized module containing a NINA B306 module, based on
Nordic nRF52480 and containing a Cortex M4F. The BMI270 and BMM150 jointly provide a 9 axis IMU. The module
can either be mounted as a DIP component (when mounting pin headers), or as a SMT component, directly
soldering it via the castellated pads.

    Arduino® Nano 33 BLE Sense Rev2 2.5.3 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.
  • Page 11 Arduino® Nano 33 BLE Sense Rev2 Power tree NOTE: Since V feeds V 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.
