SJ3 3v3 Jumper

1.6 Processor

The Main Processor is a 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-board internal I
NOTE: As opposed to other Arduino Nano boards, pins A4 and A5 have an internal pull up and default to be used as an I
recommended.

1.7 Crypto

The crypto chip in Arduino IoT boards is what makes the difference with other less secure boards as it provides a secure way to store secrets (such as certificates) and
accelerates secure protocols while never exposing secrets in plain text.
Source code for the Arduino Library that supports the Crypto is available [8]

1.8 3.4 IMU

Arduino Nano 33 BLE has an embedded 9 axis IMU which can be used to measure board orientation (by checking the gravity acceleration vector orientation or by using the
3D compass) or to measure shocks, vibration, acceleration and rotation speed.
Source code for the Arduino Library that supports the IMU is available [9]

1.9 Barometer and Temperature Sensor

The embedded Barometer and temperature sensor allow measuring ambient pressure. The temperature sensor integrated with the barometer can be used to compensate
the pressure measurement.
Source code for the Arduino Library that supports the Barometer is available [10]
