Arduino Nano 33 IoT User Manual

Arduino® Nano 33 IoT
9 / 18 Arduino® Nano 33 IoT / Rev. 01 - 06/12/2021
3.4 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 [10]
3.5 IMU
Arduino Nano 33 IoT has an embedded 6 axis IMU which can be used to measure board orientation (by checking
the gravity acceleration vector orientation) or to measure shocks, vibration, acceleration and rotation speed.
Source code for the Arduino Library that supports the IMU is available [11]
