Arduino® Nano 33 IoT
Product Reference Manual
SKU: ABX00027
Description
Nano 33 IoT is a miniature sized module containing a Cortex M0+ SAMD21 processor, a WiFi+BT module based on
ESP32, a crypto chip which can securely store certificates and pre-shared keys and a 6 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.
Target areas:
Maker, enhancements, basic IoT application scenarios

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 as an I C Bus so usage as analog inputs is not recommended. -
Page 9: Crypto
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. -

4.1 Getting started - IDE If you want to program your Arduino 33 IoT while offline you need to install the Arduino Desktop IDE [1] To connect the Arduino 33 IoT to your computer, you’ll need a Micro-B USB cable. This also provides power to the board, as indicated by the LED. -
Page 11: Board Recovery
4.6 Board Recovery All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up the processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by double- tapping the reset button right after power up. -
