SJ3 3v3 Jumper

2.2 Processor

The Main Processor is an Arm® Cortex®-M4F running at up to 64MHz. Most of its pins are connected to the
external headers, however some are reserved for internal communication with the wireless module and the on-
2
board internal I C peripherals (IMU and Crypto).
NOTE: As opposed to other Arduino Nano boards, pins A4 and A5 have an internal pull up and default to be used
2
as an I C Bus so usage as analog inputs is not recommended.

2.3 IMU

The Arduino Nano 33 BLE Sense Rev2 provides IMU capabilities with 9-axis, by combination of the BMI270 and
BMM150 ICs. The BMI270 includes both a three axis gryroscope as well as an three axis accelerometer, while the
BMM150 is capable of sensing magnetic field variations in all three dimensions. The information obtained can be
used for measuring raw movement parameters as well as for machine learning.
